Abstract

本发明公开了一种彩膜基板及其制造方法,彩膜基板包括基板、彩膜层、遮光层和共通电极层,彩膜层包括红色、绿色和蓝色色阻块;遮光层设置在彩膜层上,遮光层包括遮光块;共通电极层设置在遮光层上;红色、绿色和蓝色色阻块中的任意两者之间的交汇处与遮光块对应。本发明能有效地降低对液晶显示面板对外部环境光的反射强度。

Description

彩膜基板及其制造方法 技术领域
[0001] 本发明涉及显示技术领域, 特别涉及一种彩膜基板及其制造方法。
背景技术
[0002] 液晶显示面板会对部分射向该液晶显示面板的外部环境光进行反射。 液晶显示 面板对外部环境光的反射会降低该液晶显示面板所显示的图像的对比度和在强 光环境下的显示内容的可见度, 因此降低液晶显示面板对外部环境光的反射作 用有助于提升其显示效果。
[0003] 为解决上述技术问题, 传统的技术方案为:
[0004] 采用低反射率的偏光片, 以降低液晶显示面板的表面的反射率。
[0005] 然而, 传统的液晶显示面板的彩膜基板中设置有遮光层。 遮光层也称作 BM (B lack Matrix, 黑色矩阵) 。 遮光层构成了传统的液晶显示面板的子像素单元的非 开口区, 其作用是遮挡子像素单元的边缘区域和 TFT (Thin Film Transistor, 薄 膜晶体管) 区域, 避免暗态漏光。 虽然遮光层的透光率非常小 (小于 0.01%) , 但是它的光反射率 (2%~3%) 却不能被忽略, 而且遮光层在一个子像素单元内 的面积占比通常达到 20%~30%, 因此, 降低遮光层对环境光的反射率对降低传 统的液晶显示面板整体的环境光反射率有明显的效果。
[0006] 在传统的液晶显示面板的彩膜基板中, 遮光层紧贴玻璃基板, 彩膜层在遮光层 上方。 由于遮光层紧贴玻璃基板, 入射的外部环境光会在玻璃基板和遮光层的 界面被反射。
[0007] 因此, 上述降低液晶显示面板对外部环境光的反射作用的技术方案的效果不够 理想。
[0008] 故, 有必要提出一种新的技术方案, 以解决上述技术问题。
