Abstract

PURPOSE: To obtain a high contrast ratio by providing an optical compensating layer which compensates optical anisotropy remaining when an electrooptic cell is placed in a light shield state in addition to the electrooptic liquid crystal cell.
CONSTITUTION: The orienting films 105 and 106 of the upper and lower substrates of the electrooptic liquid crystal cell 001 are rubbed as shown by arrows 141 and 142 for orientation, and the liquid crystal has π orientation in the cell. The retardation value Δnd of the liquid crystal layer of this cell is 50nm when light is cut off and the contrast ratio in the absence of the optical compensating layer is 1:8, but the retardation value when an optical compensating layer 110 whose Δnd is about 50nm is stuck is about 0nm when the light is cut off and the contrast ratio is ≥(1:100) or ≥10 times as large as that before the optical compensating layer is inserted.
