Patent ID: 7767286

Claim:
A polarizing plate comprising at least a polarizing film, a pressure-sensitive adhesive layer, and an optical compensation sheet; and having an absolute value of Y, defined by the following equation, equal to or smaller than 6.0×10 −4 : Y=− 7.0×10 5 ×Cn+ 4.3×10 −13 ×E− 1.34×10 −3 where Cn (1/Pa) is photoelastic modulus of said pressure-sensitive adhesive layer and E(Pa) is modulus of elasticity of said optical compensation sheet; wherein said pressure-sensitive adhesive layer comprises an acrylic pressure-sensitive adhesive; and wherein said acrylic pressure-sensitive adhesive comprises a polymer comprising a repeating unit derived from a monomer represented by formula (I) below: where R 1 represents a hydrogen atom or methyl group; R 2 represents a hydrogen atom or substituent; each of R 3 and R 4 independently represents a hydrogen atom or substituent; m represents an integer of 0 or larger, n represents an integer from 0 to 5, and for the case where each of m and n is an integer of 2 or larger, a plurality of each of R 2 , R 3 and R 4 may be same or different.
