摘要： A pixel has a first liquid crystal domain. In the first liquid crystal domain, first and second pretilt directions of liquid crystal molecules, defined by first and second alignment films, respectively, intersect with each other at substantially right angles. Also, in the first liquid crystal domain, when a signal voltage is applied to the liquid crystal layer to display the highest gray scale, liquid crystal molecules, located around the center of a plane of the liquid crystal layer and around the middle of the thickness of the liquid crystal layer, are tilted in a first direction that substantially equally divides the first and second pretilt directions into two. A driver applies a signal voltage to the liquid crystal layer of the pixel every vertical scanning period. At least while display gray scales are changing from the lowest gray scale into the highest one, the driver applies a voltage that is at least 0.96 times as high as the threshold voltage Vth of the liquid crystal layer in a vertical scanning period just before the signal voltage is applied to display the highest gray scale.

摘要： The present invention provides a multi-domain type liquid crystal display device with a vertical alignment liquid crystal layer that can get a display operation done without making the viewer sense any unnaturalness and with the decrease in optical transmittance minimized. In the liquid crystal display device of this invention, the liquid crystal layer of each pixel has liquid crystal regions in which liquid crystal molecules tilt in multiple different directions when a voltage is applied between first and second electrodes. Each pixel has an opaque portion arranged on a boundary between the liquid crystal regions. The opaque portion is provided for at least one of the substrates so that when a voltage is applied between the first and second electrodes, the liquid crystal molecules neighboring the boundary will tilt while turning one of their end portions, which is closer to the substrate with the opaque portion, away from the boundary. The opaque portion includes a first shielding layer and a second shielding layer, which overlaps with the first shielding layer with a predetermined gap left between them.

摘要： A pixel of a liquid crystal display device of the present invention includes a liquid crystal layer 42, a pixel electrode 12 and a counter electrode 22 opposing each other via the liquid crystal layer, a pair of vertical alignment films 32a, 32b, and alignment sustaining layers 34a, 34b formed by a photopolymerized material on surfaces of the alignment films which are closer to the liquid crystal layer. The pixel electrode has cruciform trunk portions 12h, 12v which are positioned so as to coincide with polarization axes of the pair of polarizing plates and a plurality of branch portions 12a, 12b, 12c, and 12d extending from the cruciform trunk portions in directions of approximately 45°. The counter electrode has a cruciform opening 22a which is positioned so as to oppose the cruciform trunk portions. When a predetermined voltage is applied across the liquid crystal layer, four liquid crystal domains are formed. The pretilt azimuth of a liquid crystal molecule included in a region corresponding to each of the four liquid crystal domains is regulated by the alignment sustaining layers.
