Description

一种液晶显示面板及其制作方法 技术领域
本发明涉及液晶显示器技术领域，特别是涉及一种液晶显示面板及其制作方法。
 背景技术
如图1和2所示，现有的液晶显示面板包括：第一基板10、第二基板20，第一基板10譬如为COA（color filter on array）基板，即在阵列基板上制作彩色滤光膜，第一基板10包括数据线12和扫描线11，第二基板20上设置有黑色矩阵13；
在第一基板的内侧涂布有配向膜材料，在形成配向膜时，图像传感器根据像素单元两侧的数据线12的位置，分别对像素单元的四个分区101-104中，左侧的两个分区和右侧的两个分区进行上下配向；在第二基板的内侧也涂布有配向膜材料，像素单元在第二基板上的投影具有两个分区105、106，在形成配向膜时，图像传感器根据像素单元两侧的黑色矩阵13的位置，对这两个分区进行左右配向；最后两个基板组合后，使得每个像素内部形成四个显示畴，如图3中201-204所示。
但是当第一基板为BOA（BM on Array）基板时，由于BOA基板是将第二基板上的黑色矩阵也制作在阵列基板上，因此由于第二基板缺少图像传感器对位的基准，无法对BOA基板的对置基板使用图像传感器进行对位，使得显示效果较差。
因此，有必要提供一种液晶显示面板及其制作方法，以解决现有技术所存在的问题。

 本发明的最佳实施方式
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。在图中，结构相似的单元是以相同标号表示。
请参照图4，图4为本发明的第二基板上单个像素的光配向示意图。
本发明的液晶显示面板，其包括：第一基板、第二基板、液晶层，所述液晶层位于所述第一基板和所述第二基板之间。
其中所述第一基板包括：色阻层、遮光层，器件阵列层、第一配向膜；所述遮光层包括遮光块，即黑色矩阵；所述器件阵列层包括数据线、扫描线以及由所述数据线和所述扫描线限定的像素单元；所述第一配向膜是以所述数据线为第一光配向参照物，对第一配向膜材料进行光配向处理来形成的。
如图4所示，所述第二基板30包括间隔件组合层、第二配向膜；所述间隔件组合层包括主间隔子23、次间隔子24和辅助间隔子21、22；所述第二配向膜是以至少两个所述辅助间隔子组成的连线为第二光配向参照物，对第二配向膜材料进行光配向处理来形成的；即每个所述第二光配向参照物由至少两个所述辅助间隔子的连线组成；
所述第一基板还可包括第一透明导电层，所述第一透明导电层包括像素电极。所述第二基板还可包括第二透明导电层，所述第二透明导电层包括公共电极。
由于现有技术的液晶显示面板的第二基板上没有设置黑色矩阵，导致无法设置图像传感器进行光配向的具体位置，从而无法设置图像传感器进行光配向的具体位置，不能使机台按照预定参数进行配向；而本发明通过在第二基板上设置第二光配向参照物，方便图像传感器设置光配向的具体位置，提高了光配向对位的准确性，提高了显示效果。
优选地，至少两个所述辅助间隔子21或者22组成的连线的位置与所述扫描线在所述第二基板上的投影位置相对应。即根据所述扫描线在所述第二基板的投影位置设置至少两个所述辅助间隔子。至少两个所述辅助间隔子21组成的连线与所述像素单元的上侧的扫描线对应，至少两个所述辅助间隔子22组成的连线与所述像素单元的下侧的扫描线对应。
由于像素单元由数据线和扫描线限定形成，因此在扫描线对应位置处设置所述辅助间隔子，使得制程更简便，进一步提高第二基板的光配向的准确性，确保第二基板上的配向膜与第一基板上的配向膜相对应，更好地提高显示效果。
优选地，所述辅助间隔子是与所述主间隔子和/或所述次间隔子相同的光罩工序形成的。更优选地，所述辅助间隔子通过与主间隔子、次间隔子的同一光罩工序中形成，从而节省生产成本。
从上述可以看出，每个所述第二光配向参照物包括至少两个所述辅助间隔子；较优选地，所述第二光配向参照物中相邻两个所述辅助间隔子之间的间距为大于10微米小于等于14微米。距离太小浪费间隔子材料，增加成本；距离太大，对位准确度不能满足较高精度的要求。

优选地，所述主间隔子和所述次间隔子各距离所述辅助间隔子至少5微米，以防止在制程过程中损坏主间隔子和次间隔子。
优选地，结合图1，所述第一配向膜包括第一区域101、第二区域102、第三区域103、第四区域104；其中所述第一区域101和所述第二区域102的配向膜沿第一方向排布，譬如向下排布；所述第三区域103和所述第四区域104的配向膜沿第二方向排布，譬如向上排布；

优选地，所述第一区域、所述第二区域、所述第三区域、以及所述第四区域面积相等；所述第五区域和所述第六区域的面积相等；从而便于得到四个面积大小相等的显示畴，使面板显示的色彩更加均匀，提高对比度。
本发明的液晶显示面板的制作方法包括以下步骤：
S101、以所述数据线作为第一光配向参照物，对所述第一基板上的第一配向膜材料进行光配向处理，以在所述第一基板上形成所述第一配向膜；
所述第一配向膜材料譬如为聚酰亚胺，使用偏正光对其照射后，可在所述第一基板上形成所述第一配向膜；

优选地，所述辅助间隔子是与所述主间隔子和/或所述次间隔子相同的光罩工序形成的。
更优选地，即在第二基板上涂布间隔子材料，通过同一掩模板对所述间隔子材料进行显影、曝光，以形成所述辅助间隔子、所述主间隔子、所述次间隔子。

即对所述第一区域和所述第二区域照射第一方向的偏正光，从而得到沿第一方向排布的所述第一区域和所述第二区域的配向膜；对所述第三区域和所述第四区域照射第二方向的偏正光，从而得到沿第二方向排布的所述第三区域和所述第四区域的配向膜；
优选地，如图4所示，所述第二配向膜包括第五区域301、第六区域302；其中所述第五区域301的配向膜沿第三方向排布；譬如向右排布，所述第六区域的配向膜沿第四方向排布，譬如向左排布；所述第五区域301与所述第一区域101和所述第三区域103对应，所使第六区域302与所述第二区域102和所述第四区域104对应。从而将两个基板组合后，使得所述像素单元具有四个显示畴。
即对所述第五区域照射第三方向的偏正光，从而得到沿第三方向排布的所述第五区域的配向膜；对所述第六区域照射第四方向的偏正光，从而得到沿第四方向排布的所述第六区域的配向膜。
优选地，所述第一区域、所述第二区域、所述第三区域、以及所述第四区域面积相等；所述第五区域和所述第六区域的面积相等，从而得到四个面积大小相等的显示畴。

综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
