본 발명은 고온 내구성이 우수한 위상차층 부착 편광판을 제공하는 것이다. 본 발명의 실시형태의 위상차층 부착 편광판은 두께가 7㎛ 이상의 편광자를 포함하는 편광판과, 액정 화합물의 배향 고화층인 제1 위상차층과, 음의 복굴절을 나타내는 폴리머를 포함하는 수지 필름으로 구성되는 제2 위상차층을 포함한다. The purpose of the present invention is to provide a retardation layer-equipped polarizing plate having excellent high-temperature durability. A retardation layer-equipped polarizing plate according to an embodiment of the present invention comprises: a polarizing plate including a polarizer with a thickness of 7 μm or more; a first retardation layer being an alignment fixed layer of a liquid crystal compound; and a second retardation layer comprising a resin film including a polymer that exhibits negative birefringence.
