参见图 3 , 为本发明提供本发明提供一种偏光片结构， 其包括自上而下排列 的： 偏光片主体 11、 静电吸附膜 12、 离型膜 13。
该静电吸附膜 12位于偏光片主体 11和离型膜 13之间， 在液晶显示面板成 盒的偏贴制程中， 会先移去偏光片的离型膜 13 , 在利用偏光片上棵露的静电吸 附膜 12将偏光片主体 11贴附于液晶显示面板的上基板和下基板上。
本发明所采用的静电吸附膜 12是一种不涂胶膜， 靠本身静电吸附来粘着物 品上起保护作用。 静电吸附膜 12—般多用于对胶黏剂或者胶水残留比较敏感的 表面， 例如玻璃， 镜片， 高光塑胶面， 亚克力等非常光滑的表面。 静电吸附膜 12外部感觉不到静电， 是自粘膜。
由于本发明中采用静电吸附膜替代了原偏光片中的压力感应胶， 该静电吸 附膜利用其静电原理将偏光片主体吸附在液晶显示面板的基板表面， 而不需要 借助任何胶粘剂， 因此， 在偏光片需要重工的时候， 并无残留胶留在基板的表 面， 因此具有清洁方便的效果； 另外静电吸附膜也不会使偏光片从基板上撕去 的时候受到破坏， 因此偏光片在撕下来之后可以反复使用， 有效地节约了资源。
在具体的实现方式中， 所述偏光片主体 11为寻常光偏振型偏光片。 其偏光 特性为： 寻常偏振态的入射光可穿过该偏光片主体 11 , 非寻常偏振态的入射光 穿过该偏光片主体 11时将被吸收。

相应的， 本发明还提供一种液晶显示面板， 包括： 上基板 2a, 下基板 2b, 液晶层 3 , 上偏光片 la, 下偏光片 lb; 所述液晶层 3位于所述上基板 2a和下基 板 2b之间； 所述上偏光片 la贴附于所述上基板 2a上，所述下偏光片 lb贴附于 所述下基板 2b上；
所述上偏光片 la和所述下偏光片 lb均包括自上而下排列的： 偏光片主体、 静电吸附膜、 离型膜。 上偏光片和上偏光片的结构示意图如图 3所示。
在液晶显示面板成盒的偏贴制程中， 会先移去偏光片的离型膜 13 , 在利用 偏光片上棵露的静电吸附膜 12将偏光片主体 11贴附于液晶显示面板的上基板 和下基板上。
在具体实现中， 所述上偏光片的和下偏光片的偏光片主体 11可以有以下四 种组合类型：
第一， 所述上偏光片的和下偏光片的偏光片主体 11同为非寻常光偏振型偏 光片。
使用非寻常偏振型偏光片的液晶显示面板在交大的视角范围内均可获得较 高的对比度， 从而提升图像的显示品质， 并且非寻常光偏振型偏光片的耐热温 度问 200°C , 其比寻常光偏振型偏光片更耐高温。 另外， 该偏光片主体 11的厚 度一般小于 100微米， 厚度相当轻薄， 因此将其设置在液晶显示面板的相应的 基板的内侧时， 几乎不会对液晶显示面板的操作电压造成不良影响。
第二， 所述上偏光片的和下偏光片的偏光片主体 11同为寻常光偏振型偏光 片。
第三， 所述上偏光片的偏光片主体 11为非寻常光偏振型偏光片， 所述下偏 光片的偏光片主体 11为寻常光偏振型偏光片。
第四， 所述上偏光片的偏光片主体 11为寻常光偏振型偏光片， 所述下偏光 片的偏光片主体 11为非寻常光偏振型偏光片。 第三和第四方式中， 由于相互正交的非寻常光偏振型偏光片和寻常光偏振 型偏光片的光抽相互平行， 对任何角度入射的光波的漏光都能互补， 因此上偏 光片和下偏光片搭配使用一非寻常光偏振型偏光片和一寻常光偏振型偏光片， 可以显著降低大角度的漏光， 从而进一步改善液晶显示面板的图像显示品质。
需要说明的是， 本发明提供的液晶显示面板中， 上偏光片和下偏光片的位 置可以有不同的设置， 具体参见图 4~图7。
参见图 4, 为本发明提供的液晶显示面板实施例一的结构示意图。
本实施例一中，所述上偏光片 la贴附于所述上基板 2a外侧； 所述下偏光片 lb贴附于所述下基板 2b外侧。
参见图 5 , 为本发明提供的液晶显示面板实施例二的结构示意图。
本实施例二中，所述上偏光片 la贴附于所述上基板 2a内侧； 所述下偏光片 lb贴附于所述下基板 2b内侧。
将偏光片设置在基板内侧可以使得偏光片不易被划伤， 耐化学溶剂， 使液 晶显示面板的性能更优。
参见图 6, 为本发明提供的液晶显示面板实施例三的结构示意图。
本实施例三中，所述上偏光片 la贴附于所述上基板 2a外侧； 所述下偏光片 lb贴附于所述下基板 2b内侧。
参见图 7, 为本发明提供的液晶显示面板实施例四的结构示意图。
本实施例四种，所述上偏光片 la贴附于所述上基板 2a内侧； 所述下偏光片 lb贴附于所述下基板 2b外侧。
实施本发明提供的液晶显示面板， 由于其中的偏光片采用静电吸附膜 12替 代了原偏光片中的压力感应胶， 该静电吸附膜 12利用其静电原理将偏光片主体
11 吸附在液晶显示面板的基板表面， 而不需要借助任何胶粘剂， 因此， 在偏光 片需要重工的时候， 并无残留胶留在基板的表面， 因此具有清洁方便的效果； 另外静电吸附膜 12也不会使偏光片从基板上撕去的时候受到破坏， 因此偏光片 在撕下来之后可以反复使用， 有效地节约了资源。 并且， 本发明提供的液晶显 示面板， 其偏光片的偏光片主体采用非寻常光或寻常光偏振型偏光片， 可以达 到不同的图像显示品质。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明， 不 能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通 技术人员来说， 在不脱离本发明构思的前提下， 还可以做出若干筒单推演或替 换， 都应当视为属于本发明的保护范围。
