Problems solved by technology

[0006] However, cellulose ester-based films are materials that not only have disadvantages in terms of cost but also have disadvantages of high water permeability and poor water resistance
Due to such high water vapor permeability / poor water resistance, a large amount of water vapor permeation may continuously occur during use, and a phenomenon of swelling from the polarizer may occur, which may cause light leakage

Abstract

The present invention relates to an optical laminate which includes a polymer substrate and an anti-glare layer and in which rubber particles having a cross-section diameter of 10-500 nm are present within 50% of the thickness of the anti-glare layer from the interface between the polymer substrate and the anti-glare layer, a polarizing plate including the optical laminate, and a liquid crystal panel and a display device which include the polarizing plate.

Description

technical field [0001] Cross References to Related Applications [0002] This application claims Korean Patent Application No. 10-2018-0140845 filed with the Korean Intellectual Property Office on November 15, 2018 and Korean Patent Application No. 10-2018-0140846 filed with the Korean Intellectual Property Office on November 15, 2018 priority or interest, the disclosure of which is incorporated herein by reference in its entirety. [0003] The present disclosure relates to an optical laminate, a polarizing plate, and a display device. Background technique [0004] Liquid crystal display devices have various advantages such as power saving, light weight, and thinness, and thus are used at the highest rate among various display devices. In such a liquid crystal display device, a polarizer is provided on the image display surface side of the liquid crystal cell. Therefore, in order to prevent the polarizer from being damaged when handling / using the liquid crystal display d...
