[0104] A black pigment was used as liquid pigment dispersion (A) containing 30% by weight of pigment. Specifically, including silver-tin alloy (TMP-DC-1, Sumitomo Osaka Cement Co., Ltd. (company)) (solid content: 30%, weight ratio of silver to tin=7:3) The liquid pigment dispersion (A-1) and the liquid pigment dispersion (A-2) comprising carbon black (CI-M-050, Sakata Co., Ltd. (company)) are as listed in Table 1. Than mixed. Aliphatic polyurethane (B-1) (SUO-1000, Shin-A T&C Co., Ltd. (company)) and acrylic pressure-sensitive adhesive resin (WA-9263, manufactured by Wooin Chem Tech) (B-2) Used as a binder resin (B). Dipentaerythritol hexaacrylate (Hanong Chemistry Co., Ltd.) was used as the reactive unsaturated compound (C). In addition, a photocurable initiator Yanjia solid 369 (Irgacure 369) (D-1) and a heat curable initiator melamine curing agent (M60, manufactured by Wooin Chem Tech Co., Ltd.) (D-2) were used as initiators. As an initiator (D), propylene glycol methyl...

Abstract

Provided are a polarizing plate and a display device comprising the same, the polarizing plate comprising: a polarizing film; a polarizing film protection film arranged on at least one surface of thepolarizing film; an adhesive layer interposed between the polarizing film and the polarizing film protection film; and a printing layer impregnated in the adhesive layer and formed on at least part ofthe edge of the adhesive layer, wherein a curve ensuring portion is formed on at least one surface of the printing layer.

Description

technical field [0001] The present invention relates to a polarizing plate and an optical display including the same. Background technique [0002] For a liquid crystal display or an organic light emitting display, the grayscale of each pixel may be adjusted via optical modulation of transmitted light or self-emission of the pixel in response to an input image signal. The layer used to modify the transmitted light or the luminance level of each pixel is called a modulation layer. The liquid crystal layer of the liquid crystal display and the organic light emitting layer of the organic light emitting display correspond to the modulation layer. [0003] Since the liquid crystal layer is not a light valve that completely blocks light, the liquid crystal display includes two polarizers placed on both sides of the liquid crystal layer in the vertical direction, ie, on the backlight side and on the observer's viewing side. [0004] In the organic light emitting display, the orga...
