摘要:
A liquid crystal panel includes a glass substrate with pixel electrodes that are arranged in a matrix shape, TFTs that are connected to the pixel electrodes, and a glass substrate with an opposing electrode and color filters that are arranged in a matrix shape. A liquid crystal layer is formed in a space between the glass substrates by filling a ferroelectric liquid crystal into the space. When writing display data, and when deleting display data that has been written, a voltage, not including 0V, that becomes a voltage potential, or in other words, a voltage that is greater than a threshold voltage at which the optical characteristic of the filled ferroelectric liquid crystal changes is applied between the opposing electrode and pixel electrodes. An image is displayed over all gradation numbers, including the low-gradation side, and the display characteristic is improved.

In a field sequential display method the light emission intensities of the luminous colors are controlled to realize a plurality of color reproduction regions having different areas and make the color purity variable. In the case of high-resolution image display, a first control method is adopted in which in synchronism with the input of the pixel data of one of the luminous colors, the light of the one of the luminous colors is emitted and the lights of the other luminous colors are not emitted. In the case of coarse image display, a second control method is adopted in which in synchronism with the input of the pixel data of one of the luminous colors, the light of the one of the luminous colors and the lights of the other luminous colors are emitted. By the second method, the color purity is slightly decreased to suppress the visual irritation.

A liquid crystal display device comprising: a peripheral electrode 31 that is formed around the outside of a display region 1a on a liquid crystal panel 1 and that generates an orientation state that is equivalent to that of the display region 1a; and an inverted electrode 32 that is formed around the outside of the peripheral electrode 31 and that generates an orientation state that has polarity opposite to that of the display region 1a; wherein the peripheral electrode 31 and the inverted electrode 32 have bipectinate construction and are arranged on both sides of a non-oriented buffer region 33. Orientation defects that are generated in a seal are trapped inside the buffer region 33 due to the existence of the peripheral electrode 31 and inverted electrode 32 that have different growth directions, so the orientation defects do not intrude into the display region 1a.

The present invention provides a manufacturing method of a liquid crystal display device capable of achieving uniform alignment of monostable ferroelectric liquid crystal having spontaneous polarization, and provides the liquid crystal display device. The liquid crystal (monostable ferroelectric liquid crystal having spontaneous polarization) showing a phase sequence, either isotropic liquid phase-cholesteric phase-chiral smectic C phase, isotropic liquid phase-chiral nematic phase-chiral smectic C phase, or isotropic liquid phase-cholesteric phase-smectic A phase-chiral smectic C phase, from a high temperature side to a low temperature side, is sandwiched between two glass substrates having transparent electrodes and alignment films whose pretilt angle is not more than 2° and rubbing directions are parallel. In an alignment treatment which is performed to obtain a monostable state after heating the liquid crystal, an electric field with electric field strength of not less than 2 V/μm is applied in the vicinity of the transition temperature from a higher temperature phase than chiral smectic C phase to the chiral smectic C phase.

In a liquid crystal display device, one or a plurality of partition walls adhering to the two substrates are provided in a region between the adhesive member for sealing the peripheral portions of the two substrates and a display region located inside the adhesive member so as to reduce stress applied to the liquid crystal substance. Even when stress is applied to the liquid crystal substance in the peripheral portion of the substrate, the stress is reduced by the partition wall and is not transmitted to the display region on the opposite side of the partition wall. Therefore, even when a crack occurs in the peripheral portion of the substrate due to the stress, the propagation of the crack is stopped by the partition wall, and the crack does not enter the display region.

A display panel is provided that has a multilayer structure made of a colored glass layer having a desired shape and optical characteristics and a non-colored glass layer having high transparency, as well as high productivity. The display panel has a non-colored glass layer and a colored glass layer contacting the non-colored glass layer. A multilayer structure is formed that includes a colored paste layer and a non-colored paste layer. In the colored paste layer, crystallization glass powder that is crystallized at the temperature TA and coloring agent are diffused. In the non-colored paste layer, glass powder whose softening point is the temperature TB that is higher than the temperature TA. The multilayer structure is heated to the temperature TC that is higher than the temperature TB and is lower than the softening point of the crystallization glass powder after the crystallization to be burned, so that the non-colored glass layer and the colored glass layer are formed simultaneously.
摘要:
Local losses of material of transparent electrodes, in a plasma display panel including transparent electrodes, bus electrodes and, a dielectric layer covering these electrodes, are prevented by using a plasma display panel according to the present invention. The plasma display panel is formed on at least one substrate of a pair of substrates provided opposite each other via a discharge space. An element, which is a main element of the bus electrode composition, is included in the composition of the dielectric layer. Since the main element of the bus electrode is included in the dielectric layer, local losses of the transparent electrode can be prevented even through the high temperature baking process of the dielectric layer. A preferred choice as the main element of the bus electrode composition is copper, but other elements are also suitable and will perform acceptably.

摘要:
Within one sub-frame or one frame, values of an application voltage of one polarity and an application voltage of the other polarity, and respective retention periods are different. The value of the application voltage of the polarity when dark displaying is carried out is set to be greater than the value of the application voltage of the polarity when bright displaying is carried out, and the retention period thereof is set to be shorter. When the value of the application voltage of the one polarity (the polarity when the bright displaying is carried out correspondingly to a display data) is assumed to be V1, the retention period thereof is assumed to be T1, the value of the application voltage of the other polarity (the polarity when the dark displaying is carried out) is assumed to be V2 and the retention period thereof is assumed to be T2, the value of (V1·T1)/(V2·T2) is set to be in a range between 0.7 and 1.3 and preferably set to be in a range between 0.9 and 1.1.
