Description

一种液晶显示面板 技术领域
本申请涉及显示技术领域，尤其涉及一种液晶显示面板。
 背景技术
液晶显示器（LCD）具有低成本，高解析度，高对比度，响应速度快等特点，是目前市场上非常重要的显示器之一。液晶显示器主要由阵列基板、彩膜基板以及设置于阵列基板和彩膜基板之间的液晶层构成。为了便于液晶配向，阵列基板和彩膜基板的表面会涂布一层聚酰亚胺（PI）膜层，PI材料采用滴下的方式并且经过扩散以均匀的涂布在阵列基板和彩膜基板上。
然而，在PI液的扩散过程中，PI液扩散至阵列基板或彩膜基板上与色阻层接触的通孔处时，由于PI液的粘度较大，流入通孔的PI液不够，使得通孔内形成的PI膜较薄或者无法形成PI膜，从而使得色阻层内部离子进入液晶层中，造成通孔处液晶的电压发生变化，从而导致通孔处显示亮度不均匀。

本申请的实施方式
为使本申请的目的、技术方案及效果更加清楚、明确，以下参照附图并举实施例对本申请进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
本申请针对现有的液晶显示面板中，PI液扩散至阵列基板或彩膜基板上与色阻层接触的通孔处时，由于PI液的粘度较大，流入通孔的PI液不够，使得色阻层内部离子进入液晶层中，造成通孔处液晶的电压发生变化，从而导致通孔处显示亮度不均匀的技术问题。本申请可以解决上述问题。
一种液晶显示面板，如图1所示，所述液晶显示面板包括相对设置的第一衬底基板11和第二衬底基板21，所述第一衬底基板11与所述第二衬底基板21之间设置有液晶层60和色阻层40，所述色阻层40上设置有导电电极，所述导电电极上设置有配向膜层。
其中，所述导电电极上设置有贯穿所述导电电极且与所述色阻层40接触的通孔50，与所述通孔50对应的位置处设置有位于所述导电电极远离所述色阻层40的一侧的支撑柱30，所述支撑柱30的制备材料包括分子筛。
需要说明的是，分子筛是一种人工合成的具有筛选分子作用的化合物。分子筛在结构上有许多孔径均匀的孔道和整齐排列的孔穴，不同孔径的分子筛可以把大小和形状不同的分子分开，分子筛具有吸附性能、离子交换性能以及催化性能等作用。
需要说明的是，配向膜层的制备材料包括但不限于聚酰亚胺（PI），通过在制备支撑柱30的材料中添加分子筛，并将支撑柱30设置于与通孔50对应的位置处，这样在导电电极上形成配向膜层时，即使流入通孔50的PI液不够导致色阻层40内部离子进入液晶层60中，此时利用分子筛吸附离子的功能，可以有效的将色阻层40内析出的离子吸附在分子筛内部，从而就可以消除离子对于液晶层60中的液晶的影响，防止通孔50处液晶的电压发生变化导致通孔50处显示亮度不均匀，改善斜纹。
具体的，所述色阻层40可以设置于所述第一衬底基板11与所述导电电极之间，所述色阻层40还可以设置于第二衬底基板21与所述导电电极之间。
具体的，所述第一衬底基板11上依次层叠设置有像素电极18和第一配向膜层19；所述第二衬底基板21上依次层叠设置有共通电极22和第二配向膜层23，所述支撑柱30设置于所述第二配向膜层23上。
其中，所述通孔50设置有多个，所述支撑柱30包括多个与所述通孔50一一对应的支柱。
需要说明的是，每一支柱中均含有分子筛，从而可以就近吸收，避免从通孔50中析出的离子在液晶层60中扩散。
进一步的，所述支撑柱30包括主支撑和次支柱32，所述主支柱31与所述第一配向膜层19和所述第二配向膜层23触接，以用于保持第一配向膜层19与第二配向膜层23之间有足够的空间用于容纳液晶层60。
其中，所述次支柱32与所述第二配向膜层23间隔设置。
需要说明的是，像素电极18与共通电极22之间存在电场，离子在电场的作用下一般会向第一衬底基板11或第二衬底基板21扩散，因此支柱只要在与通孔50对应的区域处就可以对离子进行很好的吸收。
参见图1，在一实施方式中，所述色阻层40设置于所述第一衬底基板11与所述像素电极18之间，所述导电电极包括设置于所述色阻层40上的像素电极18，所述配向膜层包括设置于所述像素电极18上的第一配向膜层19，所述通孔50贯穿所述像素电极18。
参见图2，所述色阻层40设置于所述第二衬底基板21上时，所述色阻层40设置于所述第二衬底基板21与所述共通电极22之间，所述导电电极包括设置于所述阵列层上的共通电极22，所述配向膜层包括设置于所述共通电极22上的第二配向膜层23，所述通孔50设置于所述共通电极22上且贯穿所述共通电极22。
具体的，所述分子筛的制备材料可以为水合硅铝酸盐，水合硅铝酸盐由二氧化硅（SiO2）和三氧化二铝（SiO2）反应形成，可以对水合硅铝酸盐中SiO2和Al2O3的分子比进行设计，制备得到不同孔径的分子筛，从而对色阻内析出的离子进行吸附，同时避免液晶分子被吸附到分子筛中。
需要说明的是，形成支撑柱30时，可以将吸附离子的分子筛材料与有机进行混合，在第二配向膜层23上固定后形成支撑柱30，其中，所述支撑柱30中所述分子筛的质量分数为5%～20%，所述支撑柱30中所述分子筛的质量分数也可以为10%。
如图3所示，在一实施方式中，所述第一衬底基板11上还设置有阵列层，所述阵列层包括设置于所述第一衬底基板11上的有源层12、覆盖所述有源层12的第一绝缘层13、设置于所述第一绝缘层13上的栅极14、覆盖所述栅极14的第二绝缘层15以及设置于所述第二绝缘层15上的源漏金属层16。
具体的，色阻层40设置于所述第一衬底基板11与所述像素电极18之间时，所述色阻层40设置于所述阵列层上。
其中，所述通孔50贯穿所述色阻层40，并且，所述通孔50延伸至源漏金属层16的表面，所述像素电极18通过所述过孔与所述源漏金属层16触接。
在一实施方式中，所述色阻层40与所述像素电极18之间还设置有有机膜层17，所述通孔50贯穿所述有机膜层17；所述有机膜层17用于改变色阻层40的表面平整性，防止电场互相干扰，可有效改善由于地形因素造成的液晶显示装置的显示亮度不均，降低寄生电容，减少由电负载过大造成的闪烁等显示异常，提升显示装置的品质。
在一实施方式中，色阻层40包括多个间隔设置的色阻块，所述共通电极22上还设置有黑色矩阵24，所述黑色矩阵24的位置与相邻两个所述色阻块之间的间隙对应，所述第二配向膜层23覆盖所述黑色矩阵24。
本申请的有益效果为：通过在制备支撑柱30的材料中添加分子筛，并将支撑柱30设置于与通孔50对应的位置处，这样在导电电极上形成配向膜层时，即使流入通孔50的PI液不够导致色阻层40内部离子进入液晶层60中，此时利用分子筛吸附离子的功能，可以有效的将色阻层40内析出的离子吸附在分子筛内部，从而就可以消除离子对于液晶层60中的液晶的影响，防止通孔50处液晶的电压发生变化导致通孔50处显示亮度不均匀，改善斜纹。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
