Description

液晶显示面板及其制备方法 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及其制备方法。
 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。通常液晶显示面板由彩膜基板(CF，Color Filter)、阵列基板、夹于彩膜基板与阵列基板之间的液晶(LC，Liquid Crystal)组成。通常情况下，为了使阵列基板与彩膜基板之间形成一定间隙以灌注液晶，彩膜基板在最后一道工序中制作间隔物(Photo Spacer)。间隔物(Photo Spacer)是起到面内支撑作用的间隙子，间隔物(Photo Spacer)需要一定的韧性，可以起到防止液晶显示面板上下板的氧化铟锡金属层短路并维持一定的盒厚(Cell gap)以填充液晶的作用；同时，间隔物(Photo Spacer)还需要具有一定的弹塑性，以保证面板在受到外力时能产生一定的缓冲形变，避免显示面板半成品（Open Cell）产生永久损坏。
目前在显示面板设计中，间隔物临界尺寸（Photo spacer Critical Dimension，PSCD）和间隔物高度（Photo spacer heigh，PSH）的设计及计算很关键，通过调整这两个参数既能保证间隔物(Photo Spacer)起到足够的支撑力，又能保证液晶边界（LC Margin）足够方便生产；然而，在实际的面板生产中，还存在一些与间隔物(Photo Spacer)相关的课题无法通过调节这两个参数完美解决。
首先是面板因移动导致显示不均现象（Moving Mura），其形成原因是面板受变形挤压后上下板会形成错位，使得原本有黑色矩阵遮挡的区域出现漏光，严重影响面板显示质量，通过改变间隔物临界尺寸和间隔物高度无法解决面板因移动导致显示不均现象这一问题；另一问题是显示面板在受振动影响时，由于间隔物(Photo Spacer)对顶位置处的聚酰亚胺破膜导致的碎屑漏光及局部暗态不均，这一问题形成的根因是间隔物(Photo Spacer)将聚酰亚胺薄膜顶破，由于要保证间隔物(Photo Spacer)的支撑力，无法选用具有足够塑性的材料，这一问题也很难通过改变间隔物临界尺寸进行调整。
因此，有必要提供一种液晶显示面板及其制备方法，以解决现有的液晶显示面板中出现的上述问题。
 技术问题
现有的液晶显示面板，由于间隔物为单一单层的有机树脂材料，导致容易出现像素漏光或局部暗态显示不均的现象，进而影响了液晶显示面板的显示质量的技术问题。

 本发明的实施方式
本发明实施例针对现有的液晶显示面板中，由于间隔物为单一单层的有机树脂材料，导致传统的液晶显示面板容易出现像素漏光或局部暗态显示不均的现象，进而影响了液晶显示面板的显示质量的技术问题，本实施例能够解决该缺陷。
如图1所示，为现有的液晶显示面板在上下基板发生偏移的截面示意图。其中，所述液晶显示面板包括相对设置的阵列基板10与彩膜基板20、及配置于所述阵列基板10与彩膜基板20之间的液晶层30；所述阵列基板10包括第一金属层101以及像素电极102，所述第一金属层101包括扫描线与公共电极线。所述彩膜基板20包括黑色矩阵201。
具体地，传统的液晶显示面板制作工艺，均是单独制造阵列基板10和彩膜基板20，然后再将阵列基板10和彩膜基板20进行对位成盒(Cell)。
在所述阵列基板10和所述彩膜基板20进行对位成盒时，由于对位精度的限制，极易出现对位偏差，使得所述阵列基板10沿着D1方向偏移，所述彩膜基板20沿着D2偏移，导致原本有所述黑色矩阵201遮挡的区域沿着D3方向出现漏光，且由于间隔物(Photo Spacer)是压缩状态的，间隔物(Photo Spacer)移位以后受地形等原因影响无法回复到原始位置，导致漏光不会消失，宏观上会造成黑底白框画面下的垂直串扰 (V-Crosstalk)的出现，严重影响面板显示质量。通过改变间隔物临界尺寸和间隔物高度无法解决面板因移动导致显示不均现象这一问题。
如图2所示，本发明提供一种液晶显示面板，包括相对设置的阵列基板 10与彩膜基板20、以及配置于所述阵列基板10与彩膜基板20之间的液晶层30。
具体地，所述阵列基板10包括第一基板11，以及在所述第一基板11上从下到上依次设置的第一金属层12、栅极绝缘层13、有源层14、第二金属层15、钝化层16、及像素电极17。所述彩膜基板20包括第二基板21、设于所述第二基板21上的黑色矩阵 23与彩色色阻层22、设于所述黑色矩阵23与彩色色阻层22上的公共电极24、及设于所述公共电极24上的多个间隔物(Photo Spacer)40。
其中，多个所述间隔物(Photo Spacer)40对应设置于所述黑色矩阵23的正下方；所述间隔物(Photo Spacer)40包括设置于所述公共电极24上的支撑间隔物(Photo Spacer 1)41以及设置于所述支撑间隔物(Photo Spacer 1)41上的缓冲间隔物(Photo Spacer 2)42，所述支撑间隔物(Photo Spacer 1)41由具有强韧性的第一有机树脂材料构成，所述缓冲间隔物(Photo Spacer 2)42由具有强弹塑性且高摩擦系数的第二有机树脂材料构成。
具体地，所述第一有机树脂材料的韧性大于所述第二有机树脂材料的韧性，所述第一有机树脂材料的弹塑性以及摩擦系数均小于所述第二有机树脂材料的弹塑性以及摩擦系数。
优选地，所述间隔物(Photo Spacer)40为主间隔物( Main Photo Spacer), 所述缓冲间隔物(Photo Spacer 2)42靠近所述阵列基板10侧的表面与所述像素电极17相接触，导致所述间隔物(Photo Spacer)40处于压缩状态。
优选地，所述支撑间隔物(Photo Spacer 1)41以及所述缓冲间隔物(Photo Spacer 2)42经同一道光罩工艺曝光而成。其中，所述支撑间隔物(Photo Spacer 1)41的厚度大于所述缓冲间隔物(Photo Spacer 2)42的厚度。这样更有利于使所述间隔物(Photo Spacer)40起到原来的支撑作用。
具体地，所述第一基板11与所述第二基板21均为玻璃基板。
具体地，所述阵列基板10中的所述有源层14包括非晶硅层及设于所述非晶硅层上的n型掺杂非晶硅层。
具体地，所述第一金属层12包括扫描线与公共电极线，所述第二金属层15包括数据线；所述扫描线与所述数据线在水平方向上互相垂直，围成多个像素单元。所述彩膜基板20上对应的每一所述像素单元设有一个所述间隔物(Photo Spacer )40。
进一步地，所述彩色色阻层22包括红色色阻层、绿色色阻层以及蓝色色阻层，所述红色色阻层、所述绿色色阻层以及所述蓝色色阻层中的任意两种之间间隔设置有所述黑色矩阵23。
优选地，所述像素电极17以及所述公共电极24的材料均为氧化铟锡。
本发明实施例的优势在于所述间隔物(Photo Spacer)40采用双层结构设计，底层强韧性的所述支撑间隔物(Photo Spacer 1)41可以起到原来间隔物的支撑作用，上层的塑弹性的所述缓冲间隔物(Photo Spacer 2)42可以起到很好的缓冲吸震作用，防止间隔物顶破聚酰亚胺层，有助于改善液晶显示面板暗态不均现象，且由于所述缓冲间隔物(Photo Spacer 2)42的摩擦系数较高，能有效的防止上下板偏移，所述间隔物(Photo Spacer)40位置也不易移动，可起到有效改善液晶显示面板因移动导致显示不均的目的。
如图3所示，为本发明实施例提供的液晶显示面板的制备方法流程图。其中，所述方法包括：
S10，在第一基板11上从下到上依次制备第一金属层12、栅极绝缘层13、有源层14、第二金属层15、钝化层16以及像素电极17，形成阵列基板10。

S30，在所述公共电极24上形成多个间隔物40，所述间隔物40包括设置于所述公共电极24上的支撑间隔物41以及设置于所述支撑间隔物41上的缓冲间隔物42。
具体地，所述S30还包括：
首先，在所述公共电极24上先沉积一层韧性较强的第一有机树脂材料；之后，在所述第一有机树脂材料上再沉积一层弹塑性较好且摩擦系数较高的第二有机树脂材料。然后，在所述第二有机树脂材料覆盖光阻进行统一曝光，形成一种两段式的间隔物(Photo Spacer)40。其中，多个所述间隔物(Photo Spacer)40对应设置于所述黑色矩阵23的正下方；所述间隔物(Photo Spacer)40包括设置于所述公共电极24上的支撑间隔物(Photo Spacer 1)41以及设置于所述支撑间隔物(Photo Spacer 1)41上的缓冲间隔物(Photo Spacer 2)42，所述支撑间隔物(Photo Spacer 1)41由具有强韧性的所述第一有机树脂材料构成，所述缓冲间隔物(Photo Spacer 2)42由具有强弹塑性且高摩擦系数的所述第二有机树脂材料构成；所述第一有机树脂材料的韧性大于所述第二有机树脂材料的韧性，所述第一有机树脂材料的弹塑性以及摩擦系数均小于所述第二有机树脂材料的弹塑性以及摩擦系数，如图4C所示。
优选地，所述间隔物(Photo Spacer)40为主间隔物( Main Photo Spacer), 所述子间隔物(Photo Spacer 2)42靠近所述阵列基板10侧的表面与所述像素电极17相接触，导致所述间隔物(Photo Spacer)40处于压缩状态。
