摘要： An active matrix liquid crystal display device includes: a liquid crystal layer; two substrates sandwiching the liquid crystal layer; and electrodes respectively provided in the two substrates, the electrodes applying voltage across the liquid crystal layer. A first electrode (15) in the substrate including a pixel selecting element (11) has a striped electrode pattern (15c) aligning liquid crystal molecules along a stripe line direction when voltage is applied across the liquid crystal layer. A contact (25h) of the first electrode (15) with the selecting element (11) is formed in a region opposed to, along a film thickness direction, a first region to which a signal liner (GLi) is allocated. This provides a liquid crystal display device in which a contact is made with the pixel electrode having the striped electrode pattern having the periodical arrangement, while alignment disorder of the liquid crystal molecules is not reflected on display.

摘要： A VA-mode liquid crystal display device which includes a pair of alignment sustaining layers 34a and 34b formed by a photopolymerized material on surfaces of a pair of vertical alignment films 32a and 32b which are closer to a liquid crystal layer, and a cruciform opening 22a provided only in a counter electrode. When a predetermined voltage is applied across the liquid crystal layer, four liquid crystal domains are formed such that the azimuths of the directors of the respective liquid crystal domains are different from one another and form an angle of about 45′ relative to the polarization axes of a pair of polarizing plates. When no voltage is applied across the liquid crystal layer, the pretilt azimuths of liquid crystal molecules included in regions respectively corresponding to the four liquid crystal domains are regulated by the alignment sustaining layers 34a and 34b.

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.
