The present invention is to acquire a polarizing plate with improved durability of a polarizer and phase difference layer. The polarizing plate includes a polarizer containing dichroic azo pigments, a first cured product layer, a second cured product layer, and a phase difference layer including a cured product of a polymerizable liquid crystal compound, which come in contact and are stacked in order. The first cured product layer is a cured product layer of a polyvinyl alcohol-based resin composition and the second cured product layer is a cured product layer of a cationic polymerizable composition. [과제] 본 발명은 편광자 및 위상차층의 내구성이 모두 향상된 편광판을 얻는 것을 과제로 한다. [해결 수단] 이색성 아조 색소를 포함하는 편광자와, 제1 경화물층과, 제2 경화물층과, 중합성 액정 화합물의 경화물을 포함하는 위상차층이 이 순으로 접하여 적층되고, 상기 제1 경화물층은 폴리비닐알코올계 수지 조성물의 경화물층이고, 상기 제2 경화물층은 양이온 중합성 조성물의 경화물층인 편광판이 제공된다.
