    • Disclosed is a liquid crystal display and a polarizing plate used in the same. The liquid crystal display includes a liquid crystal cell and a first polarizing plate and a second polarizing plate respectively provided on each side of the liquid crystal cell. The first polarizing plate and the second polarizing plate each includes a polyvinyl alcohol polarizing film and protective films provided on both sides of the polyvinyl alcohol polarizing film, the protective films that are provided on surfaces opposite to the liquid crystal cell the first polarizing plate and the second polarizing plate each has the vapor transmissivity of 100 g/m Day or less, and the protective films that are provided on surfaces abutting the liquid crystal cell of the first polarizing plate and the second polarizing plate each has the vapor transmissivity of more than 1,500 g/m Day. When the protective films that are provided on surfaces opposite to the liquid crystal cell of the first polarizing plate and the second polarizing plate each has a UV absorption ability, the protective films that are provided on surfaces abutting the liquid crystal cell of the first polarizing plate and the second polarizing plate each has the vapor transmissivity of more than 200 g/m Day.
    • 公开了一种液晶显示器和偏光板。 液晶显示器包括分别设置在液晶单元的每一侧的液晶单元和第一偏振板和第二偏振板。 第一偏振板和第二偏振板各自包括聚乙烯醇偏振片和设置在聚乙烯醇偏振片两侧的保护膜,保护膜设置在与液晶单元相反的表面上,第一偏振片和 第二偏光板的蒸气透过率为100g / m以下,并且设置在与第一偏振片和第二偏光板的液晶单元抵接的面上的保护膜的蒸气透过率为1500以上 g / m天。 当设置在与第一偏振片和第二偏振片的液晶单元相对的表面上的保护膜各自具有UV吸收能力时,设置在与第一偏振板的液晶单元相邻的表面上的保护膜 并且第二偏振板各自具有大于200g / m 2日的蒸汽透过率。
