本发明的显示面板可以是TFT-LCD（Thin Film Transistor Liquid Crystal Display，薄膜晶体管液晶显示面板）等显示面板。
参考图5，图5为本发明的显示面板的示意图。
本实施例的显示面板包括薄膜晶体管阵列基板201、彩色滤光片基板101、液晶层202。其中，所述彩色滤光片基板101与所述薄膜晶体管阵列基板201叠加组合为一体，以形成一液晶盒。所述液晶层202设置于所述薄膜晶体管阵列基板201和所述彩色滤光片基板101之间。所述液晶层202包括液晶分子2021。

所述像素单元用于向所述液晶分子2021施加一第一电场，所述第一电场是由具有第一电压差的所述第一像素电极和所述第二像素电极形成的。
在所述显示面板中，所述薄膜晶体管阵列基板201和所述彩色滤光片基板101之间绝缘，也就是说，所述薄膜晶体管阵列基板201和所述彩色滤光片基板101之间的连接是非导电性的，即，所述薄膜晶体管阵列基板201和所述彩色滤光片基板101之间不存在电性连接。所述彩色滤光片基板101不向所述液晶分子2021施加电场作用力。
参考图2至图4，图2至图4为在本发明的显示面板内形成所述第一配向膜501和所述第二配向膜502的示意图。
在本实施例中，所述第一配向膜501是由第一聚合物单体2022经过紫外光401照射而聚合形成的，所述第二配向膜502是由第二聚合物单体2023单体经过所述紫外光401照射而聚合形成的。

在本实施例中，所述彩色滤光片基板101还包括电极层1011。所述电极层1011设置于所述第二表面和所述第二配向膜502之间，所述电极层1011用于和所述像素电极2011共同形成所述第一配向膜501和所述第二配向膜502。
其中，所述第一配向膜501是由所述第一聚合物单体2022在第二电场的作用下聚集到所述第一表面处，并经过所述紫外光401照射而聚合形成的，其中，所述第二电场是通过向所述电极层1011和所述像素电极2011施加电压而聚合固化形成的。所述第二配向膜502是由所述第二聚合物单体2023在所述第二电场的作用下聚集到所述第二表面处，并经过所述紫外光401照射而聚合固化形成的。所述第二电场是通过将所述薄膜晶体管阵列基板201的所述像素电极2011和所述彩色滤光片基板101的所述电极层1011由额外的导体连接起来，并通过所述导体向所述像素电极2011和所述电极层1011施加电压，以使所述像素电极2011和所述电极层1011之间具有第二电压差来形成的。
通过上述技术方案，可以以非机械接触的方式在所述薄膜晶体管阵列基板201和/或所述彩色滤光片基板101上形成所述第一配向膜501和/或所述第二配向膜502，以对靠近薄膜晶体管阵列基板201和/或所述彩色滤光片基板101的液晶分子进行配向；因此可以避免因利用机械接触的方式形成配向膜而导致所述显示面板中出现亮度不均的现象（Mura），降低显示异常出现的概率。
此外，通过上述技术方案所形成的所述面板有利于向所述液晶分子2021提供更大的配向作用力（配向锚定力），从而降低所述显示面板显示图像的响应时间。
参考图1，图1为本发明的彩色滤光片基板101的示意图。
在本实施例中，所述电极层1011的第三表面上设置有第一沟槽阵列，所述第一沟槽阵列包括至少两第一沟槽1012，所述第一沟槽1012用于在所述第二配向膜502的形成过程中塑造所述第二配向膜502的形状，以使所述第二配向膜502的第四表面具有第二沟槽阵列，所述第二沟槽阵列与所述第一沟槽阵列对应。所述第二沟槽阵列包括至少两第二沟槽。
其中，所述第三表面为所述电极层1011面向所述液晶层202的一面，所述第四表面为所述第二配向膜502面向所述液晶层202的一面。
在上述技术方案中，由于所述电极层1011的所述第三表面上设置有所述第一沟槽阵列，因此，在所述显示面板的工作过程中，即，在所述薄膜晶体管阵列基板201通电后，所述液晶分子2021将会沿着所述第二沟槽的走向来进行取向，这样有利于使得所述显示面板具有良好的暗态效果。

在所述步骤c1（所述步骤6031）之前，所述步骤C（所述步骤603）还包括：
c3、利用额外的导体将所述薄膜晶体管阵列基板201的所述像素电极2011和所述彩色滤光片基板101的所述电极层1011连接起来，并通过所述导体向所述像素电极2011和所述电极层1011施加电压，以使所述像素电极2011和所述电极层1011之间具有第二电压差。

此外，通过上述技术方案所形成的所述面板有利于向所述液晶分子2021提供更大的配向作用力（配向锚定力），从而降低所述显示面板显示图像的响应时间。
参考图1和图8，图8为本发明的显示面板的制作方法的第三实施例的流程图。本实施例与上述第一或第二实施例相似，不同之处在于：
在所述步骤D（所述步骤701）后，所述方法还包括以下步骤：
E（步骤801）、在所述电极层1011的第三表面上设置第一沟槽阵列，以在所述第二配向膜502形成的过程中塑造所述第二配向膜502的形状，使得所述第二配向膜502的第四表面具有第二沟槽阵列。
所述第一沟槽阵列包括至少两第一沟槽1012，所述第二沟槽阵列包括至少两第二沟槽。
其中，所述第二沟槽阵列与所述第一沟槽阵列对应。

  16. 根据权利要求15所述的显示面板的制作方法，其中，在所述步骤A之前，所述方法还包括以下步骤：
    D、在所述彩色滤光片基板的所述第二表面上设置一电极层。
  17. 根据权利要求16所述的显示面板的制作方法，其中，在所述步骤D后，所述方法还包括以下步骤：
    E、在所述电极层的第三表面上设置第一沟槽阵列，以在所述第二配向膜形成的过程中塑造所述第二配向膜的形状，使得所述第二配向膜的第四表面具有第二沟槽阵列；
    其中，所述第二沟槽阵列与所述第一沟槽阵列对应。
  18. 根据权利要求15所述的显示面板的制作方法，其中，在所述步骤B之前，所述方法还包括以下步骤：
    F、将第一聚合物单体和第二聚合物单体混合到所述液晶分子中。
  19. 根据权利要求18所述的显示面板的制作方法，其中，所述步骤C包括以下步骤：
    c1、向所述薄膜晶体管阵列基板和所述彩色滤光片基板施加电压，以使得所述第一聚合物单体和所述第二聚合物单体分别聚集在所述第一表面处和所述第二表面处；以及
    c2、利用紫外光照射所述第一聚合物单体和所述第二聚合物单体，以使所述第一聚合物单体和所述第二聚合物单体分别聚合固化为所述第一配向膜和所述第二配向膜。
  20. 根据权利要求19所述的显示面板的制作方法，其中，在所述步骤c1之前，所述步骤C还包括：
    c3、利用额外的导体将所述薄膜晶体管阵列基板的所述像素电极和所述彩色滤光片基板的所述电极层连接起来，并通过所述导体向所述像素电极和所述电极层施加电压，以使所述像素电极和所述电极层之间具有第二电压差。
