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，具体涉及一种液晶显示面板及其制备方法。
 背景技术
随着显示技术的发展，各种新兴技术不断涌现并丰富了各种新的显示应用场景。其中，透明显示可以用于货物展示柜，电子公告牌，抬头显示器等领域，受到了广泛的关注。目前实现透明显示的技术路线主要有两种，一种是传统的液晶显示面板，通过红绿蓝白像素设计，提高其穿透率，但透过率还是较低（小于20%）；另一种是利用OLED等主动式发光技术，这种技术穿透率较高，但在对比度，亮度上的缺陷大大限制了其应用。
基于此，聚合物网络液晶显示（polymer network liquid crystal，PNLC）应运而生，其所使用的液晶材料与普通液晶材料有着明显不一样，聚合物网络液晶显示是一种液晶聚合物复合材料。在聚合物网络液晶中，聚合物以网络织构分布在液晶中，而液晶以一种连续相形态存在。当液晶与聚合物折射率不匹配时，会发生强烈的散射呈现不透明态，而两者的折射率匹配时呈现透明态，因此可以通过对PNLC施加电场控制透过率的高低，从而被广泛的应用在智能窗户等领域等新型显示。但，在现有的PLNC显示其中，仍存在对比度不高的问题。

聚合物网络液晶显示因其特殊的显示模式，已被广泛的应用于智能窗户等新兴的显示模式中，请参阅图1，提供了一种现有常规的聚合物网络液晶显示面板的截面膜层结构示意图，具体地，包括：
第一基板11，在所述第一基板11上依次配置有薄膜晶体管层111、色阻层112、绝缘层113、像素电极层114以及第一配向膜115；
第二基板12，在所述第二基板12上依次配置有黑色矩阵层121、公共电极层122、第二配向膜123以及间隔层124；
聚合物网络液晶层13，配置于所述制作完成的第一基板11与第二基板12之间。
在该聚合物网络液晶中，未通电时，光线呈现散射状态，除部分被黑色矩阵层遮挡的光线外，大多光线均射出，即形成了较严重的暗态漏光现象，即导致了较低的对比度。
基于此，为了改善这种暗态漏光现象，本发明实施例提供了一种显示面板，该显示面板的截面结构请参阅图2，包括：
第一基板21，所述第一基板21上配置有第一色阻层212；
第二基板22，所述第二基板22与所述第一基板21对组设置，所述第二基板22上配置有第二色阻层225；以及
聚合物网络液晶层23，配置于所述第一基板21与所述第二基板22之间，
其中，所述第一色阻层212包括多个第一子色阻，所述第二色阻层225包括与所述第一色阻层中的多个第一子色阻分别在颜色与位置上对应设置的多个第二子色阻，即第一色阻层212中的任意一个第一子色阻，在对应的位置均设置了一个相同颜色的第二子色阻，需要补充的是，此处描述的对应位置是指任意第一子色阻与其对应的第二子色阻，两者在第一基板21上的投影重合或部分重合。
在一些实施例中，所述第一基板为阵列基板，所述第二基板为彩膜基板。
在一些实施例中，所述多个第一子色阻中任意相邻的两个第一子色阻之间颜色相异。通过这种颜色互异的色阻排布方式，在任意一子像素中，背光发出的光线经过第一色阻层212后形成某一特定颜色的光，在暗态时，该像素内的光线向各个角度散射，其中，散射至相邻子像素的光，会被相邻的颜色相异的第二色阻层225过滤，从而在一定程度上降低了暗态漏光，提升对比度。可以理解的是，因所述第二色阻层225与所述第一色阻层212分别对应设置，故所述第二色阻层225具有相同的子色阻排布，在此不再赘述。
在一些实施例中，所述第一色阻层212配置于所述第一基板21靠近所述聚合物网络液晶层23的一侧，所述第二色阻层225配置于所述第二基板22背离所述聚合物网络液晶层23的一侧，因第二基板22具有一定的厚度，将所述第二色阻层225配置于所述第二基板22背离所述聚合物网络液晶层23的一侧，即将所述第二色阻层225配置于所述第二基板22沿出光方向的外侧，如此一来，即可利用第二色阻层225过滤掉暗态时的更大角度的散射光，便也过滤掉了更大比例的散射光，更进一步降低暗态漏光的程度
在一些实施例中，所述第一色阻层中的多个第一子色阻之间依次间隔设置，所述第二色阻层中的多个第二子色阻之间依次相邻设置，以便获得更大面积的第二子色阻，过滤暗态时更多的散射光，通常情况下，所述第二子色阻的面积相较对应的所述第一子色阻的面积大5-15%。
在一些实施例中，所述多个第一子色阻之间的任意一者在所述第一基板上的正投影，位于与所述第一子色阻对应的所述第二子色阻在所述第一基板上的正投影区域内部。
在一些实施例中，所述多个第一子色阻包括多个第一红色子色阻、多个第一绿色子色阻以及多个第一蓝色子色阻。
在一些实施例中，所述多个第一子色阻包括多个第一红色子色阻、多个第一绿色子色阻、多个第一蓝色子色阻以及多个第一白色子色阻，其中，所述第一白色子色阻的个数占所述第一子色阻总个数的25%或50%。例如在一个像素内，按照R/G/B/W或R/W/G/W/B/W排列。
在一些实施例中，所述第二基板22背离所述聚合物网络液晶层23的侧面上，依次层叠配置有第二色阻层225以及保护层226，其中，所述保护层226的设置有效避免了第二色阻层225发生划伤的问题，所述保护层通常可以为透明的有机聚合物薄膜或者氮化硅薄膜。
在一些实施例中，所述第一基板21靠近所述聚合物网络液晶层23的一侧，依次层叠配置有薄膜晶体管层211、第一色阻层212、绝缘层213、像素电极层214以及第一配向膜215，
其中，所述薄膜晶体管层211包括阵列排布的多个薄膜晶体管，通常包括有源层、栅极、源极、漏极以及层间绝缘层，每一所述的薄膜晶体管与上层像素电极层214中对应的像素电极一一电性连接（图中未示出）。
在一些实施例中，所述第二基板22靠近所述聚合物网络液晶层23的侧面上，依次层叠配置有黑色矩阵层221、公共电极层222以及第二配向膜223，
其中，所述黑色矩阵层221包括多个黑色矩阵，设置于所述第一色阻层212中各个子像素间隔区域的对应位置，
所述公共电极层222通常为整面的氧化铟锡膜层，与所述像素电极层214共同作用形成电场驱动液晶的偏转。
在一些实施例中，所述聚合物网络液晶层23中还包括间隔层224，所述间隔层224包括多个支撑柱，设于非像素区域，为所述聚合物网络液晶层23提供稳定的空间。

S01：提供第一基板21，在所述第一基板21上依次形成薄膜晶体管层211、第一色阻层212、绝缘层213、像素电极层214以及第一配向膜215，所述第一色阻层212包括多个第一子色阻，即形成如图3A所示的结构；
S02：提供第二基板22，在所述第二基板22的第一表面依次形成第二色阻层225与保护层226，所述第二色阻层225包括与所述第一色阻层212中的多个第一子色阻分别对应设置的多个第二子色阻，即形成如图3B所示的结构，
其中，形成所述保护层226的步骤通常包括采用涂布工艺形成一层透明的有机聚合物薄膜，或使用化学气相沉积形成一层氮化硅薄膜；
S03：翻转所述第二基板22，在所述第二基板22的第二表面依次形成黑色矩阵层221、公共电极层222、第二配向膜223以及间隔层224，即形成如图3C所示的结构；
