Provided is a polarizing plate, which is configured with a display area and a non-display area surrounding the display area. The polarizing plate comprises: a polarizer; an adhesive layer on the upper surface of the polarizer; and a light blocking layer in which first polarizer protection films are sequentially stacked, wherein the adhesive layer comprises at least one portion of the non-display area in the adhesive layer. The light blocking layer is formed on at least one surface of the first polarizer protection film, and includes an ultraviolet curing agent. The adhesive layer is formed of an ultraviolet curing agent, and the light blocking layer is formed of a composition for a thermosetting type light blocking layer. 표시 영역과 상기 표시 영역을 둘러싸는 비 표시 영역으로 구성되는 편광판이고, 상기 편광판은 편광자, 상기 편광자의 상부면에 접착층 및 제1편광자 보호필름이 순차적으로 적층되고, 상기 접착층은 상기 접착층 내에 상기 비 표시 영역의 적어도 일부를 이루는 차광층을 포함하고, 상기 차광층은 상기 제1편광자 보호필름의 적어도 일면에 형성되고, 상기 차광층은 자외선 경화제를 포함하고, 상기 접착층은 자외선 경화형 접착제로 형성되고, 상기 차광층은 열경화형 차광층용 조성물로 형성되는 것인 편광판 및 이를 포함하는 광학 표시 장치가 제공된다.
