Description

一种液晶材料及液晶显示面板 技术领域
本发明涉及平板显示器制造技术领域，特别涉及一种液晶材料及液晶显示面板。
背景技术
随着显示技术的发展，液晶显示器(Liquid Crystal Display，LCD)等平面显示装置因具有高画质、省电、机身薄及应用范围广等优点，而被广泛的应用于手机、电视、个人数字助理、数字相机、笔记本电脑、台式计算机等各种消费性电子产品，成为显示装置中的主流。
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，BM)。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。
在液晶显示器的CF基板和TFT基板上，分别有一层薄膜材料，其主要作用是使液晶分子按一定方向排列，我们称之为配向膜(常用聚酰亚胺(PI)材料)。这种配相膜主要分为摩擦配相型PI材料和光配相型PI材料。但是，无论哪种配向材料都会有各自的缺点：首先，摩擦配相向容易造成粉尘颗粒、静电残留、刷痕等问题降低工艺良率，而光配相材料虽然可以避免这些问题，但由于材料特性受限，耐热性和耐老化性不佳，同时锚定LC分子的能力也较弱，从而影响面板的品质；其次，PI材料本身就具有高极性和高吸水性，存储和运送容易造成变质而导致配相不均，并且PI材料价格昂贵，在TFT-LCD上成膜的工艺也较为复杂，导致面板成本提高。
因此，出现了一些可以取代PI材料的小分子添加剂材料，主要包括含有烷基链的硅烷类、笼型半硅氧烷类、含烷基链的醇类等。这些小分子添加剂材料主要依靠自身极性基团吸附在基板表 面，使的液晶可以垂直取向，这种含有添加剂的液晶材料叫做自取向液晶材料。
将这种材料应用在TFT-LCD面板中，往往存在一些问题；例如液晶面板地形表面差异，主要是由于TFT表面结构为“米”字狭缝图案，像素电极所在区域分为被ITO像素电极覆盖的区域和没有被ITO像素电极的区域，而没有被ITO覆盖的区域主要为钝化层，钝化层一般分为无机材料氮化硅和有机材料绝缘膜PFA(Polymer Film on Array)。在不使用PI配向层的情况下，依靠添加剂材料吸附于基板表面进行配向时，由于添加剂材料与SiNx/PFA的作用力较弱，导致辅助配向剂与基板表面作用力的差异，形成配向不良，施加电压之后容易导致暗线或亮线缺陷。因此有必要对这种添加剂材料进行改进，以提高其锚定基板的作用，解决由于像素电极差异造成的配向力差异与亮暗线显示缺陷等问题，实现均匀配向。
技术问题
本发明提供一种液晶材料及液晶显示面板，以解决现有像素电极的差异造成的配向力差异与亮暗线显示缺陷等问题。
技术解决方案
