Circular polarizing plate

Abstract

An object of the present invention is to provide a circular polarizing plate which enables a display device to operate stably, even when the display device equipped with the circular polarizing plate is placed in a high-temperature environment, or when the circular polarizing plate in said display device is subjected to shape processing, perforation, or the like. The solution of the present invention is a circular polarizing plate, which is a circular polarizing plate sequentially comprising a first retardation plate, a polarizing plate, and a second retardation plate, wherein said first retardation plate comprises: a thermoplastic resin layer having a glass transition temperature of
