Description

彩色滤光基板、液晶显示面板及液晶显示装置 技术领域
本发明涉及显示面板技术领域,特别涉及彩色滤光基板、液晶显示面板及液晶显示装置。
背景技术
液晶显示面板一般包括阵列基板、彩色滤光基板以及设置在阵列基板和彩色滤光基板之间的液晶层。彩色滤光基板则包括RGB色阻层,RGB滤光层是LCD显示器关键的光学功能层,其作用是选择性地让红光、绿光或者蓝光穿透,这样通过控制R、G、B子像素各自的透过率就可以让LCD显示器显示彩色画面。
如图1所示,图1为现有技术中彩色滤光基板的剖视示意图,由于RGB色阻层中起显色作用的颜料(Pigment)分子或者染料(Dye)分子分子量较大,色阻层有较为明显的光散射作用。液晶和偏光片组成的光开光对大角度的散射光的暗态透过率较大,因此色阻的光散射作用会增大暗态亮度从而降低显示对比度。另一方面,色阻层上下表面起保护作用的有机层的折射率和色阻层不是完全匹配,因此色阻层还会有一定的光反射损耗。RGB色阻层存在一定的光散射和光反射损耗,这些都会影响LCD显示器的穿透率对比度等性能参数。
因此,确有必要来开发一种新型的彩色滤光基板,以克服现有技术的缺陷。
“背景技术”段落只是用来帮助了解本发明内容,因此在“背景技术”段落所揭露的内容可能包含一些没有构成本领域技术人员所知道的现有技术,在“背景技术”段落所揭露的内容,不代表该内容或者本发明一个或多个实施例所要解决的问题,也不代表在本发明申请前已被本领域技术人员所知晓或认知。
