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.

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.
