Disclosed are a polarizing plate and an optical display device including the same. The polarizing plate is a polarizing plate including a display region and a non-display region encompassing the display region, wherein the polarizing plate includes a polarizer, an adhesive layer and a first polarizer protection film, which are sequentially stacked on the polarizer, the adhesive layer includes a light shielding layer for forming at least a part of the non-display region within the adhesive layer, the light shielding layer has a plurality of print patterns which are spaced from each other, the print patterns include a first print pattern and a second print pattern formed on the first print pattern, and the second print pattern has a pattern form which differs from that of the first print pattern. La présente invention porte sur une plaque de polarisation et sur un appareil d'affichage optique comprenant cette dernière. La plaque de polarisation est une plaque de polarisation comprenant une région d'affichage et une région de non-affichage englobant la région d'affichage, la plaque de polarisation comprenant un polariseur, une couche adhésive et un premier film de protection de polariseur, qui sont empilés de manière séquentielle sur le polariseur, la couche adhésive comprenant une couche de protection contre la lumière pour former au moins une partie de la région de non-affichage à l'intérieur de la couche adhésive, la couche de protection contre la lumière ayant une pluralité de motifs d'impression qui sont espacés les uns des autres, les motifs d'impression comprenant un premier motif d'impression et un second motif d'impression formé sur le premier motif d'impression, et le second motif d'impression ayant une forme de motif qui est différente de celle du premier motif d'impression. 편광판 및 이를 포함하는 광학표시장치와 관련한 발명이 개시된다. 상기 편광판은 표시 영역과 상기 표시 영역을 둘러싸는 비 표시 영역으로 구성되는 편광판이고, 상기 편광판은 편광자, 및 상기 편광자의 일면에 접착층, 제1편광자 보호필름이 순차적으로 적층되고, 상기 접착층은 상기 접착층 내에 상기 비 표시 영역의 적어도 일부를 이루는 차광층을 포함하고, 상기 차광층은 복수 개의 인쇄 패턴이 서로 이격되어 형성되어 있고, 상기 인쇄 패턴은 제1인쇄 패턴 및 상기 제1인쇄 패턴 상에 형성된 제2인쇄 패턴으로 구성되고, 상기 제2인쇄 패턴은 상기 제1인쇄 패턴 대비 패턴 형상이 다르다.
