相对于如图1所述的设计，每个分支部区域的分支与第二主干朝向第一主干的夹角为135度，每个分支从第二主干与第一主干相交点、第二主干或第一主干出发向外延伸，像素电极结构呈“米”字型，液晶倾倒方向指向像素电极的第二主干和第一主干相交的中心点，这样中心点会形成漩涡状液晶旋转区域，出现暗纹，导致原先透光区域的透光效果变差，穿透率下降，并出现显示差异。本方案中，每个所述分支的一端或其延长线与所述第一主干或其延长线相交，另一端或其延长线与所述第二主干或其延长线相交，分支或其延长线与第二主干或其延长线所形成的开口朝向第一主干，即是说分支是面向第二主干和第一主干相交的中心点，这样可以使得液晶向第一主干和垂直主干方向倾倒，避免液晶向第二主干和第一主干相交的中心点倾倒，可避免中心点出现漩涡状液晶旋转区域，进而避免出现暗纹，透光区域的透光效果较好，穿透率较高，显示差异小。

四个所述分支部20分别包括多个分支21；
每个所述分支21或其延长线的一端与所述第一主干11或其延长线相交，另一端与所述第二主干12或其延长线相交；
所述分支21为由三段组成，呈向中心点13方向弯折弯折状。
相对于如图1所述的设计，每个分支部20区域的分支21与第二主干12朝向第一主干11的夹角为135度，每个分支21从第二主干12与第一主干11相交点、第二主干12或第一主干11出发向外延伸，像素电极1结构呈“米”字型，液晶倾倒方向指向像素电极1的第二主干12和第一主干11相交的中心点13，这样中心点13会形成漩涡状液晶旋转区域，出现暗纹，导致原先透光区域的透光效果变差，穿透率下降，并出现显示差异。本方案中，每个所述分支的一端或其延长线与所述第一主干或其延长线相交，另一端或其延长线与所述第二主干或其延长线相交，分支或其延长线与第二主干或其延长线所形成的开口朝向第一主干，即是说分支21是面向第二主干12和第一主干11相交的中心点13，这样可以使得液晶向第一主干11和垂直主干方向倾倒，避免液晶向第二主干12和第一主干11相交的中心点13倾倒，可避免中心点13出现漩涡状液晶旋转区域，进而避免出现暗纹，透光区域的透光效果较好，穿透率较高，显示差异小。同时，分支21为由三段组成并向中心点13方向弯折，可以每段与第二主干12或第一主干11的夹角不同，可以保证分支21的分布方向多，液晶的倾倒方向相应多，减小视觉色差；分支21整体是向外拱起的，降低液晶向中心点13集中倾倒的趋势，可以使得液晶向外倾倒，避免中心点13出现漩涡状液晶旋转区域，进而避免出现暗纹，透光区域的透光效果更好，穿透率更高。

另外，从中心点13往外相同次序的所述分支21或其延长线连接在第二主干12和第一主干11或两者延长线上的位置也可以相错开。
分支21或其延长线连接在第二主干12和第一主干11或两者延长线上的位置相错开，液晶偏转方向更多，减小视觉色差。

在一实施例中，所述分支21由三段组成，呈弯折状。
分支21由三段组成，并呈弯折状，每段与第二主干12或第一主干11 的夹角不同，可以保证分支21的分布方向多，液晶的倾倒方向相应多，减小视觉色差，同时分支21由三段组成不会使得像素电极1结构不会太复杂，制程简单。
在一实施例中，由三段组成的所述分支21向中心点13方向弯折。
三段组成的分支21向中心点13方向弯折，分支21整体是向外拱起的，降低液晶向中心点13集中倾倒的趋势，可以使得液晶向外倾倒，避免中心点13出现漩涡状液晶旋转区域，进而避免出现暗纹，透光区域的透光效果更好，穿透率更高。
