Abstract:
1. A polarizing plate with pressure-sensitive adhesive type optical compensation layer used for liquid crystal display, comprising a polarizing plate with optical compensation layer ( 1 ) and an optical compensation film ( 2 ) bonded to each other via a pressure-sensitive adhesive layer A, and a pressure-sensitive adhesive layer B at the opposite side of the optical compensation film ( 2 ) to the pressure-sensitive adhesive layer A, wherein both the pressure-sensitive adhesive layer A and the pressure-sensitive adhesive layer B have a tensile elasticity of 0.1 MPa or less at 23° C., the pressure-sensitive adhesive layer A and the pressure-sensitive adhesive layer B are formed respectively from a crosslinked product of a composition containing an acrylic polymer having a weight-average molecular weight of 500,000 to 2,500,000 (P the acrylic polymer (P wherein the polarizing plate with optical compensation layer (
