Abstract
The present invention relates to a polarizing plate with pressure-sensitive adhesive type optical compensation layer, comprising a polarizing plate with optical compensation layer () and an optical compensation film () 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 () to the pressure-sensitive adhesive layer A, wherein both the pressure-sensitive adhesive layers A and B have a tensile elasticity of 0.1 MPa or less at 23° C. This polarizing plate with pressure-sensitive adhesive type optical compensation layer is capable of minimizing display irregularity even when placed in a high-temperature or high-temperature and high-humidity atmosphere.
