Description

一种液晶显示面板及装置 技术领域
本发明涉及液晶显示器技术领域，特别是涉及一种液晶显示面板及装置。
背景技术
在现有的液晶显示面板中，相邻像素之间存在非驱动区域，液晶排列不受控制，会出现漏光，所以与非驱动区域相应位置设置有黑色矩阵对其进行遮光。
如图 1 所示，给出 R 、 G 、 B 三原色的刺激值与波长的图谱关系示意图，横坐标表示波长长度（单位为纳米），纵坐标表示三原色的刺激值； 101 表示 B 的波长，为 435.8 纳米， 102 表示 G 的波长，为 546.1 纳米， 103 表示 R 的波长，为 700 纳米；由于人眼的可见光的波长范围介于 390-700 纳米范围，利用色阻 R 与色阻 B 进行重叠，可以达到遮光的效果，便省去黑色矩阵的制程成本。但色阻交叠的区域为两种色阻（ R&B ）的厚度，相对于像素中央的显示区域会形成凸起的围墙结构，因此会使彩膜基板的表面不平整，不利于液晶和聚酰亚胺 (PI) 的流动，从而影响光学性能，降低显示效果。

如图 2 所示，现有技术的阵列基板 10 包括数据线 11 ，扫描线 12 ，以及由数据线 11 和扫描线 12 限定的左侧的像素和右侧的像素，左侧的像素具有一像素电极区域 201 （为鱼骨形的像素电极所在的虚线框区域），右侧的像素具有一像素电极区域 202 ；
由于像素电极区域的长边边缘距离该边缘最近的数据线之间有空隙，因此容易产生漏光，将该区域称为漏光区域 203 ，譬如像素电极区域 201 的长边边缘 13 与中间的数据线之间有空隙，如位于中间的数据线的左侧虚线框所示；像素电极区域 202 的长边边缘 14 与中间的数据线之间有空隙，如位于中间的数据线的右侧虚线框所示；
如图 3 所示，在彩膜基板 20 的衬底上，与阵列基板上的漏光区域 203 对应的位置上设置有重叠彩膜 21 ，重叠彩膜 21 包括红色彩膜 22 和蓝色彩膜 23 ，蓝色彩膜 23 重叠在红色彩膜 22 上。重叠彩膜 21 为两种色阻（ R&B ）的厚度，会使彩膜基板的表面不平整，不利于液晶和聚酰亚胺 (PI) 的流动，从而影响光学性能，降低显示效果。
请参照图 4 ，图 4 为本发明的第一种阵列基板的俯视图。
