[0104] Black pigments were used as liquid pigment dispersions (A) containing 30% by weight of pigments. Specifically, a silver-tin alloy (TMP-DC-1, Sumitomo Osaka Cement Co., Ltd. (Company)) is included (solid content: 30%, weight ratio of silver to tin = 7:3) The liquid pigment dispersion (A-1) and the liquid pigment dispersion (A-2) including carbon black (CI-M-050, Sakata Co., Ltd. (Company)) in the contents 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 Co., Ltd.) (B-2) Used as binder resin (B). Dipentaerythritol hexanoacrylate (Hanong Chemistry Co., Ltd.) was used as the reactive unsaturated compound (C). In addition, a photocurable initiator Irgacure 369 (Irgacure 369) (D-1) and a heat curable initiator melamine curing agent (M60, manufactured by Wooin Chem Tech Co.) (D-2) were used as initiators. The starting agent (D), pr...

Abstract

The present invention provides a polarizing plate and an optical display device including the same. The polarizing plate includes: a polarizing film; a protective film for the polarizing film disposed on at least one surface of the polarizing film; a bonding layer interposed between the polarizing film and the protective film for the polarizing film; and a printing layer interposed in the bonding layer and disposed on at least a part of the edge of the bonding layer, and has a curved surface fixing portion formed on one surface thereof. The present invention provides a polarizing plate that includes a printed layer to prevent elements in a non-display area from being visible from the outside, and can prevent cracks from being generated even when applied to a non-display area having a curved end. The present invention provides a polarizing plate that allows the thickness of a display device to be further reduced.

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...
