发明名称 POLARIZING PLATE, OPTICAL FILM AND IMAGE DISPLAY DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a polarizing plate that has an adhesive layer, a transparent protective film and a liquid crystal optical compensation layer, in this order on at least one surface of a polarizer, and an adhesive layer and a transparent protective film, in this order on the other surface, and that can suppress display unevenness even when used for a liquid crystal panel. SOLUTION: The polarizing plate has an adhesive layer, a transparent protective film (A), and a liquid crystal optical compensation layer, in this order on one surface of a polarizer, and has an adhesive layer and a transparent protective film (B), in this order on the other surface of the polarizer. The liquid crystal optical compensation layer is obtained by obliquely aligning the optical axis of a liquid crystal. At least one of the transparent protective film (A) and the transparent protective film (B) comprises a (meth)acrylic resin having a glutarimide unit and a (meth)acrylate unit, and has an in-plane retardation of less than 40 nm and a retardation in the thickness direction of less than 80 nm.
