Abstract

Disclosed is a polarizing plate which is sufficiently suppressed in occurrence of curling even when different transparent protective layers are arranged on the opposite sides of a polarizer. Also disclosed are a high-quality liquid crystal panel using such a polarizing plate, and an image display. Specifically disclosed is a polarizing plate with a surface protective film, which comprises a polarizing plate having a transparent protective layer (A), a polarizer and a transparent protective layer (B) in this order, and a surface protective film arranged on a surface of the transparent protective layer (A) on the opposite side of the polarizer or on a surface of the transparent protective layer (B) on the opposite side of the polarizer. The transparent protective layer (A) and the transparent protective layer (B) are of different kinds of transparent protective layer from each other.
