Abstract:
1. A polarizing plate provided with optical compensation layers comprising a polarizer, a first optical compensation layer, a second optical compensation layer, and a third optical compensation layer in the stated order, wherein: the first optical compensation layer contains a resin having an absolute value of photoelastic coefficient of 2×10 the second optical compensation layer contains a resin having an absolute value of photoelastic coefficient of 2×10 the third optical compensation layer has a relationship of nx=ny>nz, an in-plane retardation Re an absorption axis of the polarizer and a slow axis of the first optical compensation layer form an angle of 10° to 30°; the absorption axis of the polarizer and a slow axis of the second optical compensation layer form an angle of 70° to 95°; and the absorption axis of the polarizer and a slow axis of the third optical compensation layer form an angle of 70° to 95°.
