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： 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： Although portions of electrodes in proximity to a driver IC are covered with an insulating film, part of the electrodes is not covered with the insulating film. Thus, this insulating film absent region functions as an external voltage supply region that receives, from the outside, application of a voltage which is different from an output voltage from a driving unit. When the alignment of the initial state is disarranged, an alignment process is performed by short-circuiting all electrodes of the driving unit and applying a voltage from the outside, through the external voltage supply region, whereby the alignment is restored to the initial state with the driving unit being mounted on a liquid crystal panel.

摘要： A voltage corresponding to desired image data is applied to a ferroelectric liquid crystal having a spontaneous polarization at a predetermined cycle to rewrite the displayed image (period A), and then, all voltages applied to the ferroelectric liquid crystal are removed (timing C) to retain the displayed image before the removal (period B). A gate selection period (voltage application period to the ferroelectric liquid crystal) t2 before stopping the voltage application is set longer than a gate selection period (voltage application period to the ferroelectric liquid crystal) t1 in the normal display. Increasing the voltage application period to the ferroelectric liquid crystal provides a sufficient response of the liquid crystal during the gate selection period, thereby realizing high memory ability.

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 liquid crystal display device, halftones are displayed by applying voltages to liquid crystal elements so that the transmittance of liquid crystals is changed. A plurality of gradation-reference-voltage-generation circuits are provided as sources for generating the voltages to be applied to the liquid crystals to realize display of the halftones. With this configuration, gradation-reference voltages for γ characteristics for display colors are generated, and furthermore, applied voltages for the display colors are generated on the basis of the generated gradation-reference voltages. This allows for gradation display for each of the display colors, resulting in excellent image display.
