The present invention relates to a polarizing plate and, more specifically, to: a polarizing plate, which includes a polarizer and a protective film arranged on at least one side of the polarizer and has a diffusion adhesive layer and a transparent adhesive layer interposed between the polarizer and at least one protective film, wherein the diffusion adhesive layer includes a first diffusion particle and a second diffusion particle having different average particle diameters, thereby preventing a moire phenomenon to enhance visibility; and an image display device including the same. La présente invention concerne une plaque de polarisation et, plus particulièrement : une plaque de polarisation, qui comprend un polariseur et un film protecteur disposé sur au moins un côté du polariseur et qui a une couche adhésive de diffusion et une couche adhésive transparente intercalées entre le polariseur et au moins un film de protection, la couche adhésive de diffusion comprenant une première particule de diffusion et une seconde particule de diffusion ayant des diamètres de particule moyens différents, ce qui permet d'empêcher un phénomène de moiré de manière à améliorer la visibilité; et un dispositif d'affichages d'image la comprenant. 본 발명은 편광판에 관한 것으로, 보다 상세하게는 편광자 및 상기 편광자의 적어도 일측에 배치되는 보호필름을 포함하며, 상기 편광자와 적어도 하나의 보호필름 사이에 확산점착제층 및 투명점착제층이 개재되고, 상기 확산점착제층은 평균입경이 서로 다른 제1 확산입자 및 제2 확산입자를 포함함으로써, 모아레 현상을 방지하여 시인성이 향상된 편광판 및 이를 포함하는 화상 표시 장치에 관한 것이다.
