 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1，图1为本发明IPS型液晶显示面板的结构示意图；
如图1所示，IPS型液晶显示面板，包括彩膜基板20、阵列基板10、液晶层30；液晶层30位于所述彩膜基板20和所述阵列基板10之间；所述阵列基板10与所述彩膜基板20相对设置；在所述彩膜基板20的外侧还可设置有第一偏光片；在所述阵列基板10的外侧还可设置有第二偏光片。
其中所述阵列基板10上设置有数据线、扫描线以及由所述数据线和所述扫描线限定的多个像素单元，每个所述像素单元包括多个子像素；其中每个所述子像素包括像素电极11和第一公共电极12，所述第一公共电极12和所述像素电极11位于同一层，且相互交错间隔分布。每个所述子像素具有四个显示畴，所述显示畴是通过对所述像素电极11进行图形化处理以及对所述第一公共电极12进行图形化处理形成的。
现有技术IPS型液晶显示面板的子像素只具有两个显示畴，本发明通过对第一公共电极和像素电极进行图形化处理，从而增加了第一公共电极和像素电极之间的电场的方向，进而使得液晶分子有更多的偏转方向，由于液晶分子的偏转方向更多，能够增大观看视角，降低色偏。
请参照图2，图2为图1中沿AA’方向的第一种截面图。
如图2所示，所述像素电极11包括条状水平像素主干部31、条状竖直像素主干部32及条状像素分支部33，所述条状水平像素主干部31和所述条状竖直像素主干部32垂直相交，且由所述条状水平像素主干部31和所述条状竖直像素主干部32垂直相交均分形成四个像素显示区域；每个所述像素显示区域内包括多个所述条状像素分支部33，多个所述条状像素分支部33相对于所述条状水平像素主干部31和所述条状竖直像素主干部32垂直相交的中心点向外发散，即所述条状像素分支部33与所述条状水平像素主干部31或者所述条状竖直像素主干部32电性连接；每个所述像素显示区域内的多个所述条状像素分支部33之间间隔设置；

优选地，结合图2，在所有所述显示畴内，所述条状像素分支部33和所述条状公共分支部42之间的间距相等。四个公共显示区域和对应的像素显示区域组成四个显示畴，通过将所有的条状像素分支部和所述条状公共分支部之间的间距保持一致，从而能够使得第一公共电极和像素电极之间产生更加均匀的电场，从而更好地提高显示效果，进一步降低色偏。

当液晶分子的初始配向与所述水平像素主干部的方向平行，且将条状像素分支部与所述条状水平像素主干部保持上述角度，可以确保在通电后液晶分子具有一定的配向角，有利于液晶分子的偏转，提高显示效果。

优选地，结合图3，所述液晶层30内的液晶分子具有一初始配向，所述初始配向的方向与所述条状水平公共主干部61的方向平行；所述条状公共分支部63的延长线与所述条状水平公共主干部61的延长线之间的锐角角度为5度-15度，进一步优选为7-12度。
当液晶分子的初始配向与所述条状水平公共主干部的方向平行，且将条状公共分支部与所述条状水平公共主干部保持上述角度，可以确保在通电后液晶分子具有一定的配向角，有利于液晶分子的偏转，提高显示效果。
优选地，结合图3，沿水平方向上的相邻两个所述公共显示区域内的所述条状公共分支部63以所述条状竖直公共主干部62为轴成对称结构；譬如左上角和右上角的公共显示区域的条状公共分支部成轴对称结构；

请参照图4，图4为本发明FFS型液晶显示面板的结构示意图。
如图4所示，FFS型液晶显示面板，包括彩膜基板80、阵列基板70、液晶层90；液晶层90位于所述彩膜基板80和所述阵列基板70之间；所述阵列基板70与所述彩膜基板80相对设置，在所述彩膜基板80的外侧还可设置有第一偏光片；在所述阵列基板70的外侧还可设置有第二偏光片。
其中所述阵列基板70上设置有数据线、扫描线以及由所述数据线和所述扫描线限定的多个像素单元，每个所述像素单元包括多个子像素；其中每个所述子像素包括像素电极73和第一公共电极71，所述像素电极73位于所述第一公共电极71上，在所述第一公共电极71和所述像素电极73之间还可设置绝缘层72。
每个所述子像素具有四个显示畴，所述显示畴是通过对所述像素电极73进行图形化处理以及对所述第一公共电极71进行图形化处理形成的。
