Description

液晶显示装置 技术领域
本发明涉及液晶显示领域， 尤其涉及一种液晶显示装置。 背景技术
液晶显示装置（LCD, Liquid Crystal Display )具有机身薄、 省电、 无 辐射等众多优点， 得到了广泛的应用。 现有市场上的液晶显示装置大部分 为背光型液晶显示器， 其包括液晶显示面板及背光模组 （ backlight module ) 。 液晶显示面板的工作原理是在两片平行的玻璃基板当中放置液 晶分子， 两片玻璃基板中间有许多垂直和水平的细小电线， 通过通电与否 来控制液晶分子改变方向， 将背光模组的光线折射出来产生画面。
请参阅图 1 , 通常液晶显示装置由上基板（CF, Color Filter ) 100、 下 基板（TFT, Thin Film Transistor)200、 设于上基板 100与下基板 200之间 的液晶 （LC, Liquid Crystal ) 300、 设于上基板 100与下基板 200之间的 间隔物 （PS, Photo Spacer )及密封胶框 ( Sealant ) 500组成， 其成型工艺 一般包括： 前段阵列 （Array )制程（薄膜、 黄光、 蚀刻及剥膜） 、 中段成 盒（Cell )制程（TFT基板与 CF基板贴合）及后段模组组装制程（驱动 IC与印刷电路板压合） 。 其中， 前段 Array制程主要是形成 TFT基板， 以 便于控制液晶分子的运动； 中段 Cell制程主要是在 TFT基板与 CF基板之 间添加液晶； 后段模组组装制程主要是驱动 IC 压合与印刷电路板的整 合， 进而驱动液晶分子转动， 显示图像。
其中 PS 用来抵御施加于面板上的压力， 支撑与维持上下基板间的距 离。 但是如果 PS与基板的接触面积太大， 在上下发生错位后， PS受基板 的摩擦力太大， 不易恢复原理的性质， 并且摩擦变形导致周围的液晶导向 改变， 可能发生漏光现象； 但是如果 PS 与基板的接触面积太小， 则基板 在受到压力之后， 较难回复到原来的厚度。
随着面板的不断增大， 在制造和搬运等过程中， 面板的四周可能会承 受较大的压力， 而面板的内部则会承受较大的弯曲形变和错位摩擦。 现有 液晶面板未能解决这个问题。 发明内容

所述抛物线型递增的递增速度为先慢后快。

其中， 所述间隔物的相对两端与 CF基板及 TFT基板的接触面积从 CF基板与 TFT基板的中心位置向 CF基板与 TFT基板边缘位置递增； 其中， 所述间隔物的相对两端与 CF基板及 TFT基板的接触面积从 CF基板与 TFT基板的中心位置向 CF基板与 TFT基板边缘位置呈直线型 递增；
其中， 所述间隔物的相对两端与 CF基板及 TFT基板的接触面积变化 通过改变间隔物相对两端的端面面积大小来实现， 间隔物的端面面积从 CF基板与 TFT基板的中心位置向 CF基板与 TFT基板边缘位置递增； 其中， 所述间隔物于密封胶框内均匀分布于所述 TFT基板与 CF基板 之间。
