在图中，结构相似的单元是以相同标号表示。
请参照图1，图1为本发明的液晶显示面板的制作方法的第一优选实施例的流程图。本优选实施例的液晶显示面板的制作方法应用在液晶显示面板的制作中，该液晶显示面板的像素单元可包括多个显示畴。本优选实施例的液晶显示面板的制作方法包括：
步骤S101，制作阵列基板，其中阵列基板的内表面包括像素电极层；
步骤S102，制作彩膜基板，其中彩膜基板的内表面包括公共电极层；
步骤S103，在像素电极层上涂布像素配向膜，其中像素配向膜包括第一无序聚合物；
步骤S104，对像素配向膜进行第一光配向处理，使得第一无序聚合物转换为第一有序聚合物；其中根据液晶显示面板的主显示视角，确定不同的显示畴的像素配向膜进行第一光配向处理的曝光量；
步骤S105，在公共电极层上涂布公共配向膜，其中公共配向膜包括第二无序聚合物；
步骤S106，对公共配向膜进行第二光配向处理，使得第二无序聚合物转换为第二有序聚合物；
步骤S107，将阵列基板和彩膜基板进行对盒处理，以形成液晶盒。
本优选实施例的液晶显示面板的制作方法结束于步骤S107。
下面详细说明本优选实施例的液晶显示面板的制作方法的各步骤的具体流程。
在步骤S101中，在衬底基板上制作扫描线、薄膜场效应晶体管、数据线以及像素电极，以形成阵列基板，该阵列基板的内表面设置有包括像素电极的像素电极层。随后转到步骤S102。
在步骤S102中，在衬底基板上制作黑色矩阵、彩膜色阻以及公共电极，以形成彩膜基板，该彩膜基板的内表面设置有包括公共电极的公共电极层。随后转到步骤S103。
在步骤S103中，在阵列基板的像素电极层上涂布像素配向膜，该像素配向膜中包括第一无序聚合物，该第一无序聚合物中的聚合物处于无序排列状态。随后转到步骤S104。
在步骤S104中，对像素配向膜进行第一光配向处理，使得第一无序聚合物中的聚合物转换为有序排列状态，即第一无序聚合物转换为第一有序聚合物。在第一光配向处理中，使用特定方向的偏振光以特定的角度对第一无序聚合物进行曝光处理，从而形成第一有序聚合物，液晶分子在第一有序聚合物的作用下会存在一定的预倾角，从而实现了像素配向膜的配向作用。这里进行第一光配向处理时的曝光量越大，对应像素配向膜的配向角度也就越小。
因此在本步骤中，根据用户确定的液晶显示面板的主显示视角，确定不同的显示畴的像素配向膜进行第一光配向处理的曝光量，从而使得主显示视角的显示效果更好。优选的，如液晶显示面板的主显示视角对应的显示畴的像素配向膜进行第一光配向处理的曝光量大于其他显示畴的像素配向膜进行第一光配向处理的曝光量。随后转到步骤S105。
在步骤S105中，在彩膜基板的公共电极层上涂布公共配向膜，该公共配向膜中包括第二无序聚合物，该第二无序聚合物中的聚合物处于无序排列状态。随后转到步骤S106。
在步骤S106中，对公共配向膜进行第二光配向处理，使得第二无序聚合物中的聚合物转换为有序排列状态，即第二无序聚合物转换为第二有序聚合物。优选的，第二光配向处理的配向方向与第一光配向处理的配向方向垂直。随后转到步骤S107。
在步骤S107中，将步骤S104进行第一光配向处理之后的阵列基板和步骤S106进行第二光配向处理之后的彩膜基板进行对盒处理，以形成液晶盒。
这样即完成了本优选实施例的液晶显示面板的制作过程。
下面通过一具体实施例说明本优选实施例的液晶显示面板的制作过程。请参照图2，图2为本发明的液晶显示面板的制作方法的第一优选实施例中的像素单元的显示畴的示意图。图2左侧为像素单元的阵列基板侧的像素配向膜的第一光配向方向，其中上侧的像素配向膜的第一光配向方向为左倾，下侧的像素配向膜的第一光配向方向为右倾。图2中间为像素单元的彩膜基板侧的公共配向膜的第二光配向方向，其中左侧的公共配向膜的第二光配向方向为下倾，右侧的公共配向膜的第二光配向方向为上倾。这样对盒处理之后的像素单元具有左上、左下、右上、右下四个显示畴，多显示畴的设置可以增大液晶显示面板的可显示视角。这里为了提高液晶显示面板的下视角的显示效果，增大对阵列基板的下侧像素配向膜的第一光配向处理的曝光量。
请参照图3，图3为现有的液晶显示面板的不同观看视角的gamma曲线示意图。其中301为水平观看情况下的gamma曲线，其完全符合人眼对画面的观看要求。而302为具有60度的上视角、60度的下视角、60度的左视角以及60度的右视角的观看情况下的gamma曲线。虽然像素单元进行了多显示畴的划分，但是gamma曲线302与标准的gamma曲线301还是具有一定的差异。
请参照图4，图4为本发明的液晶显示面板的制作方法的第一优选实施例制作的液晶显示面板的不同观看视角的gamma曲线示意图。其中401为水平观看情况下的gamma曲线，其完全符合人眼对画面的观看要求。而402为具有60度的上视角的观看情况下的gamma曲线，403为具有60度的左视角和右视角的观看情况下的gamma曲线，404为具有60度的下视角的观看情况下的gamma曲线。其中gamma曲线403与现有的gamma曲线302相同，gamma曲线402较gamma曲线402更加远离gamma曲线401，而gamma曲线404较gamma曲线402更加接近gamma曲线401。因此本优选实施例通过对阵列基板的下侧像素配向膜的第一光配向处理的曝光量的增大，牺牲了上视角的显示效果的基础上，但是提高了下视角（主显示视角）的显示效果。这样可以在不提高液晶显示面板的制作成本的基础上，保证液晶显示面板的显示效果。
当然这里也可根据设置的主显示视角的不同，改变第一光配向处理的曝光量增大的位置。如用户需要提高上视角的显示效果，即设置上视角为主显示视角，则可增大对阵列基板的上侧像素配向膜的第一光配向处理的曝光量。
本优选实施例的液晶显示面板的制作方法根据液晶显示面板的主显示视角，确定不同的显示畴的像素配向膜进行第一光配向处理的曝光量；从而可以在降低液晶显示面板的制作成本的基础上，保证液晶显示面板的显示效果。

步骤S507，将阵列基板和彩膜基板进行对盒处理，以形成液晶盒。
本优选实施例的液晶显示面板的制作方法结束于步骤S507。

本优选实施例的液晶显示面板的制作方法根据液晶显示面板的主显示视角，确定不同的显示畴的公共配向膜进行第二光配向处理的曝光量；从而可以在降低液晶显示面板的制作成本的基础上，保证液晶显示面板的显示效果。

步骤S607，将阵列基板和彩膜基板进行对盒处理，以形成液晶盒。
本优选实施例的液晶显示面板的制作方法结束于步骤S607。
