Abstract:
1. A polarizing plate with optical compensation layers, comprising: a polarizer; a first optical compensation layer; and a second optical compensation layer, the polarizer, the first optical compensation layer, and the second optical compensation layer being stacked together in this order, wherein the first optical compensation layer is formed of a liquid crystal compound and has a relationship of nx>ny=nz and an in-plane retardation Re the second optical compensation layer has a relationship of nx=ny>nz and a thickness-direction retardation Rth an angle formed between an absorption axis of the polarizer and a slow axis of the first optical compensation layer is in a range of 25 to 65 degrees in a clockwise direction (−) or in a counterclockwise direction (+) with respect to the absorption axis of the polarizer.
