为使本发明的目的、技术方案和优点更加清楚，下面结合附图对本发明的具体实施方式进行详细说明。这些优选实施方式的示例在附图中进行了例示。附图中所示和根据附图描述的本发明的实施方式仅仅是示例性的，并且本发明并不限于这些实施方式。
在此，还需要说明的是，为了避免因不必要的细节而模糊了本发明，在附图中仅仅示出了与根据本发明的方案密切相关的结构和/或处理步骤，而省略了与本发明关系不大的其他细节。
本实施例首先提供了一种液晶面板，如图1所示，所述液晶面板包括依次叠层设置的第一偏光片1、阵列基板2、彩膜基板3和第二偏光片4，所述彩膜基板3和所述阵列基板2之间设置有液晶分子5，所述阵列基板2中阵列设置有多个像素结构2a。
其中，如图2所示，所述像素结构2a包括扫描线21和数据线22，所述扫描线21和所述数据线22相互交叉限定像素单元23，所述像素单元23包括像素驱动器件31和像素电极33，所述像素电极33通过所述像素驱动器件31电连接至所述扫描线1和所述数据线2。具体地，所述像素驱动器件31为薄膜晶体管，所述薄膜晶体管的栅极连接至所述扫描线21，源极连接至所述数据线22，漏极连接至所述像素电极33。
其中，如图3所示，所述像素电极33包括显示区域33a和环绕所述显示区域33a的非显示区域33b。所述像素电极33的显示区域33a部分包括条状的水平主干310和条状的竖直主干320，所述水平主干310与所述竖直主干320在中心位置垂直相交。由所述水平主干310与所述竖直主干320中心垂直相交所均分而成的四个象限子区域301、302、303、304中分别具有多个条状分支330，每一所述条状分支330的一端与所述水平主干310或所述竖直主干320连接，另一端与所述像素电极33的非显示区域33b部分连接，任意相邻的两个所述条状分支330之间具有狭缝340。
在本实施例中，如图3所示，位于第一象限子区域301和第三象限子区域 303中的条状分支330垂直于所述水平主干310，位于第二象限子区域302和第四象限子区域304中的条状分支330平行于所述水平主干310。需要说明的是，在另外的一些实施例中，也可以是这样设置：如图4所示，位于第一象限子区域301和第三象限子区域303中的条状分支330平行于所述水平主干310，位于第二象限子区域302和第四象限子区域304中的条状分支330垂直于所述水平主干310。
进一步地，在本实施例中，四个象限子区域301、302、303、304中的条状分支330具有相同的宽度，相邻的两个条状分支330之间的狭缝340的宽度也是完全相同，由此，所述像素电极33的显示区域33a部分关于其中心点呈90°旋转对称。
其中，为了尽可能地减小像素结构中的金属线对偏振光的衍射造成的漏光，本发明中将第一偏光片1的吸光轴设置为与水平轴具有大于0且小于90°的夹角α，第二偏光片4的吸收轴与所述第一偏光片1的吸收轴垂直。图5是本发明实施例中的偏光片的吸光轴与像素电极水平轴的位置关系的示例性图示，图中L1表示第一偏光片1的吸光轴，L2表示第二偏光片4的吸光轴。其中，夹角α较为优选的是30°～60°，最为优选的是45°。当α＝45°时，第一偏光片1的吸光轴L1与所述像素电极33中的四个象限子区域301、302、303、304中的条状分支330之间相对夹角均为45°，在减小漏光的同时，又可以最大限度地提升入射偏振光的光线透过率。
进一步地，所述像素单元23还包括公共电极线，所述公共电极线和所述像素电极呈异层结构设置，两者之间具有绝缘层。在本实施例中，如图6所示，所述公共电极线32在所述像素电极33上的正投影位于所述非显示区域33b之内，所述公共电极线32与所述像素电极33的非显示区域33b之间形成存储电容。将公共电极线32布置在非显示区域33b中，避免了公共电极线32对入射的偏振光发生衍射而产生漏光，有效地降低了像素结构的漏光程度，提高了液晶显示的对比度。
进一步地，本实施例还提供了一种液晶显示装置，参阅图7，该液晶显示装置包括液晶面板100以及背光模组200，所述液晶面板100与所述背光模组200相对设置，所述背光模组200提供显示光源给所述液晶面板100，以使所述液晶面板100显示影像。其中，所述液晶面板100采用了本发明前述实施例所提供的液晶面板。
综上所述，本发明实施例提供的液晶面板以及液晶显示装置，将像素电极中的条状分支设置为平行或垂直于水平轴(水平主干)方向，并且将偏光片的吸光轴设置为与水平轴具有大于0且小于90°的夹角，由此可以减小像素结构中的金属线对偏振光的衍射造成的漏光，提高对比度。
