摘要： A backlight device for a transmissive liquid crystal display device includes a plurality of light sources, including a cold cathode fluorescent lamp and an LED, a liquid crystal panel, and a light guide plate. The light guide plate causes light entering into it through one surface thereof to emerge out of another surface thereof toward the liquid crystal panel. A controller for the backlight device selects at least one of the cold cathode fluorescent lamp and LED, depending on brightness required for the liquid crystal display device and determines, in accordance with the required brightness, the brightness of the selected light source to operate the light source accordingly.

摘要： 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.

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.

摘要： 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.

摘要： A color display is performed by carrying out a switching between a first driving system in which the OFF timing of a light source and the end timing of a data scanning agree with each other and a second driving system in which the OFF timing of a light source and the end timing of a data scanning do not agree with each other. In case where a response time of a liquid crystal from a transmission state to a light-shielding state is sufficiently short, a color display is performed by using the first driving system to decrease a light-emitting time of a light source. On the other hand, in case where the response time of the liquid crystal from the transmission state to the light-shielding state is increased, a color display is performed by using the second driving system.

摘要： 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.

摘要： 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.
