PURPOSE:To obtain a high contrast ratio by providing a compensating layer having a double refraction effect. CONSTITUTION:A liquid crystal layer 13 which is inserted and held in a compensating cell 22 used as a compensating layer is brought to a homogeneous orientation in between upper substrate 11-1 and lower substrate 11-1. Polarization axes of the upper side and the lower side polarizing plates make an angle of 90 deg., and the direction of a direction of a liquid crystal 3 makes an angle of 45 deg. against the polarization axes of the upper and the lower polarizing plates, respectively, and makes an angle of 90 deg. against the direction of a director of the liquid crystal 13 in the cell 22. A value of retardation of the compensating cell 22 is DELTAnd=50nm. In such a way, a contrast ratio of 1:>=50is obtained and a high contrast ratio can be obtained. |
