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.
