Description

显示面板及其制造方法 技术领域
本发明涉及显示技术领域，特别涉及一种显示面板及其制造方法。
 背景技术
传统的光配向（Photo-alignment）技术为非接触式配向技术，其通过对配向层进行一定方向的光线照射，使原先各向同性的配向膜发生光化学反应而变成各向异性，从而可以对液晶分子起到配向作用。光配向技术因其几乎可以对配向层表面整个区域进行一定方向的配向，因此避免了拓印（Rubbing）配向方式中所出现的配向不良的现象，以及避免了摩擦布的局部不规则造成的配向不良的现象，减小了漏光，增加了对比度。
然而，在传统的光配向技术中，液晶显示面板的上下两基板中的配向层均是利用光线对同一种配向层材料进行照射来形成的，这会造成所述液晶显示面板的信赖性较差或者所述液晶显示面板的对比度偏低，其中，信赖性的好坏是通过ISP（Image Sticking Parameter，图像匹配的参数）来表征的。
也就是说，通过传统的光配向技术所形成的液晶显示面板不能同时具有较好的信赖性和较高的对比度。
故，有必要提出一种新的技术方案，以解决上述技术问题。

 附图说明
图1为本发明的显示面板的第一实施例的示意图；
图2为利用具有第一波长的第一光线照射第一配向材料以形成第一配向层的示意图；
图3为本发明的显示面板的制造方法的第一实施例的流程图。
 本发明的最佳实施方式
本说明书所使用的词语“实施例”意指实例、示例或例证。此外，本说明书和所附权利要求中所使用的冠词“一”一般地可以被解释为“一个或多个”，除非另外指定或从上下文可以清楚确定单数形式。
参考图1，图1为本发明的显示面板的第一实施例的示意图。
在本实施例中，所述显示面板包括薄膜晶体管阵列基板101、彩色滤光片基板102、液晶层103。所述彩色滤光片基板102和所述薄膜晶体管阵列基板101叠加组合为一体。
所述薄膜晶体管阵列基板101包括第一表面和第二表面，所述第二表面上设置有第一配向层104，所述第一配向层104包括第一配向材料。
所述彩色滤光片基板102包括第三表面和第四表面，所述第二表面和所述第三表面相向设置，所述第三表面上设置有第二配向层105，所述第二配向层105包括第二配向材料。
所述液晶层103设置于所述第二表面和所述第三表面之间。
其中，所述第一配向层104是通过利用具有第一波长的第一光线201照射所述第一配向材料来形成的，如图2所示，所述第二配向层105是通过利用具有第二波长的第二光线照射所述第二配向材料来形成的。
本发明的显示面板的第二实施例与上述第一实施例相似，不同之处在于：
在本实施例中，所述第一配向材料为光致分解反应配向材料、光致异构化反应配向材料、光致交联反应配向材料中的一种。
所述第二配向材料为光致分解反应配向材料、光致异构化反应配向材料、光致交联反应配向材料中的另一种。
在所述配向材料（所述第一配向材料或所述第二配向材料）为所述光致分解反应配向材料的情况下，当利用紫外光照射所述配向材料时，所述配向材料中平行于所述紫外光的偏振方向的配向材料高分子链发生分解反应，而垂直于所述偏振方向的配向材料高分子链方向未变，此时所述配向材料变成各向异性。
由所述光致分解反应配向材料经过所述紫外光照射而形成的配向层（所述第一配向层104或所述第二配向层105）的各向异性值较大，配向能力好，可以使得所述显示面板具有较高的对比度。
在所述配向材料（所述第一配向材料或所述第二配向材料）为所述光致异构化反应配向材料的情况下，当利用紫外光照射所述配向材料时，与所述紫外光的偏振方向平行的配向材料内部的光反应基团会由反式构型变化成顺式构型，然后再继续变成垂直于原始方向的反式构型，这样便导致配向层材料内部高分子链排列方向垂直于所述紫外光的偏振方向，变成各向异性。
由所述光致异构化反应配向材料经过所述紫外光照射而形成的配向层（所述第一配向层104或所述第二配向层105）的信赖性较好。
在所述配向材料（所述第一配向材料或所述第二配向材料）为所述光致交联反应配向材料的情况下，在线性偏振光（紫外光）照射下，所述配向材料发生二聚化加成链聚合反应（2+2），从而使聚合物薄膜表面出现各向异性分布。
同样，由所述光致交联反应配向材料经过所述紫外光照射而形成的配向层（所述第一配向层104或所述第二配向层105）的信赖性较好。
因此，上述技术方案可以使得所述显示面板同时具有较好的信赖性和较高的对比度。
在本实施例中，所述第一光线的波长与所述第二光线的波长相同。
本发明的显示面板的第三实施例与上述第二实施例相似，不同之处在于：
在本实施例中，所述第一光线的波长与所述第二光线的波长不同。
例如，所述第一光线的波长处于252至256的范围内，所述第二光线的波长处于311纳米至315纳米的范围内，或者所述第二光线的波长处于363纳米至367纳米的范围内。
或者，所述第二光线的波长处于252至256的范围内，所述第一光线的波长处于311纳米至315纳米的范围内，或者所述第一光线的波长处于363纳米至367纳米的范围内。
本发明的显示面板的第四实施例与上述第三实施例相似，不同之处在于：
在本实施例中，所述第一光线的波长为254纳米，所述第二光线的波长为313纳米或365纳米；
或者，所述第二光线的波长为254纳米，所述第一光线的波长为313纳米或365纳米。
在所述配向材料（所述第一配向材料或所述第二配向材料）为所述光致分解反应配向材料的情况下，照射所述配向材料的光线的波长为254纳米。
在所述配向材料（所述第一配向材料或所述第二配向材料）为所述光致异构化反应配向材料的情况下，照射所述配向材料的光线的波长为365纳米或313纳米。
作为一种改进，将所述光致异构化反应配向材料与热交联高分子层搭配，这样可以大幅度提高所述显示面板的信赖性。将所述光致异构化反应配向材料与热交联高分子层搭配的方式是在所述液晶层103的液晶分子中混入反应型单体，然后利用紫外光照射。
参考图3，图3为本发明的显示面板的制造方法的第一实施例的流程图。
在本实施例中，所述方法包括以下步骤：
A（步骤301）、利用具有第一波长的第一光线201照射第一配向材料，以在所述薄膜晶体管阵列基板101的所述第二表面上形成所述第一配向层104，如图2所示；
B（步骤302）、利用具有第二波长的第二光线照射第二配向材料，以在所述彩色滤光片基板102的所述第三表面上形成所述第二配向层105；
C（步骤303）、将设置有所述第一配向层104的所述薄膜晶体管阵列基板101和设置有所述第二配向层105的所述彩色滤光片基板102叠加组合为一体；

由所述光致分解反应配向材料经过所述紫外光照射而形成的配向层（所述第一配向层104或所述第二配向层105）的各向异性值较大，配向能力好，可以使得所述显示面板具有较高的对比度。
