Title
(EN) Polarizing plate
(ZH) 偏光板
Abstract
(EN)
The present invention relates to a polarizing plate having excellent durability even in a high humidity environment. More specifically, the present invention relates to a polarizing plate comprising: a polarizer; and a protective layer formed on at least one surface of the polarizer, wherein the protective layer consists of a cured product of a radical-curable composition comprising: a compound represented by [formula 1]; a vinyl ether-based compound; a carboxylic acid compound comprising at least one unsaturated double bond; and a radical initiator.
