偏光板和包含偏光板的光学显示设备
摘要：
本发明提供一种偏光板和包含偏光板的光学显示设备。所述偏光板包含偏光器、形成于所述偏光器的下部表面上的第一光学膜，和形成于所述第一光学膜的下部表面上的粘着膜。由等式1计算，所述粘着膜具有约200％或更小的溶胀度，且包含单体混合物的(甲基)丙烯酸共聚物，所述单体混合物包括具有未经取代C11到C20烷基的约5重量％(wt％)到约30wt％的(甲基)丙烯酸酯，且所述光学膜由选自环状聚烯烃树脂、聚碳酸酯树脂和丙烯酸类树脂的至少一种树脂形成。本发明偏光板具有良好透光度及良好耐久性。
摘要（英）：

The present invention provides a polarizing plate and an optical display device comprising the polarizing plate. Wherein the polarizing plate comprises a polarizer, a first optical film formed on a lower surface of the polarizer, and an adhesive film formed on a lower surface of the first optical film. (Meth) acrylic acid copolymer having a degree of swelling of about 200% or less and comprising a monomer mixture, said monomer mixture comprising an alkyl group having an unsubstituted C to C alkyl group (Wt%) to about 30% by weight of (meth) acrylate, and the optical film is formed of at least a resin selected from the group consisting of a cyclic polyolefin resin, a polycarbonate resin and an acrylic resin. The polarizing plate of the invention has good light transmittance and good durability.
