本申请实施例针对现有垂直配向型液晶显示器件存在大视角色偏的技术问题，本申请实施例用以解决该问题。
如图1所示，现有子像素为四畴设计的液晶显示器件包括栅极层101、源漏极层102、绝缘层103、公共电极层104、像素电极层105、有源层106，所述栅极层101图案化形成有栅极和扫描线，所述源漏极层102图案化形成有源漏极和数据线，所述像素电极层105图案化形成有像素电极，如图2所示，在四畴设计中，液晶方向根据像素电极的设计，液晶110的方向分别为45度、135度、225度和315度，在大视角观看液晶显示器件时，会出现大视角偏白的现象，导致出现大视角的色偏问题，而在子像素采用八畴设计时，需要增加薄膜晶体管进行控制，一般采用三个晶体管进行控制，这样会导致液晶显示器件的开口率较低，所以，现有垂直配向型液晶显示器件存在大视角色偏的技术问题。
如图3、图4所示，本申请实施例提供一种液晶显示面板，该液晶显示面板包括多个子像素201，所述子像素201包括像素电极218和薄膜晶体管，所述子像素201的形状包括正方形，所述像素电极218的形状包括圆形，所述薄膜晶体管设置于所述子像素201形成的正方形的各条边上，并通过信号线与所述像素电极218连接；
其中，所述像素电极218被狭缝分割形成多个子像素电极，所述狭缝包括穿过所述像素电极218的圆心、且相互垂直的第一狭缝311和第二狭缝312、以及第三狭缝317，所述第一狭缝311和所述第二狭缝312将所述像素电极218划分为逆时针设置的第一象限区域411、第二象限区域412、第三象限区域413、第四象限区域414；所述第三狭缝317均匀的设置在所述第一象限区域411、第二象限区域412、第三象限区域413和第四象限区域414中的至少一个区域内。

需要说明的是，图4中未示出薄膜晶体管，薄膜晶体管包括栅极、源极、漏极、有源层、绝缘层，还包括扫描线和数据线。
需要说明的是，第一狭缝311和第二狭缝312垂直将像素电极划分为多个子像素电极，第三狭缝317将像素电极划分为多个子像素电极，由于第一狭缝和第二狭缝将像素电极划分为四个子像素电极，第三狭缝是在第一狭缝和第二狭缝划定的各个象限区域进一步划分子像素电极，因此第一狭缝、第二狭缝和第三狭缝将像素电极划分形成的子像素电极的数量一定大于4，从而使得子像素的畴的数量大于4，从而增加的液晶方向。
在一种实施例中，如图4所示，所述第三狭缝317包括第四狭缝313和第五狭缝315，所述第四狭缝313位于所述第一象限区域411，所述第五狭缝315位于所述第三象限区域413，所述第四狭缝313与所述第五狭缝315的中心线处于同一直线上，且穿过所述重合区域，所述第四狭缝313和所述第五狭缝315与所述重合区域不接触；在第一象限区域和第三象限区域分别形成第四狭缝和第五狭缝，使得在沿第一象限区域至第三象限区域的方向，或者第三象限区域至第一象限区域的方向观看时，由于液晶方向的数量增大，相对于现有液晶方向数量较少，使得在该方向观看时，该方向的亮度可以分散，从而可以改善色偏，提高液晶显示面板的视角。

在一种实施例中，如图4所示，所述第四狭缝313和所述第五狭缝315分别包括三条狭缝，所述第四狭缝313将所述第一象限区域411的像素电极218划分为四个子像素电极，所述第五狭缝315将所述第三象限区域413的像素电极218划分为四个子像素电极，在第四狭缝将第一象限区域的像素电极划分为多个子像素电极，第五狭缝将第三象限区域的像素电极划分为多个子像素电极时，可以使得第四狭缝和第五狭缝将第一象限区域和第三象限区域的像素电极划分为等分的四个子像素电极，还可以将像素电极划分为等分的八个子像素电极，即在将像素电极划分为子像素电极时，保证子像素电极为等分，可以将像素电极划分为各个数量的子像素电极，从而相应的得到各个畴的子像素，相应提高液晶方向的数量，从而相应的增加改善色偏的能力，从而提高液晶显示面板的视角，缓解现有垂直配向型液晶显示器件存在大视角色偏的技术问题。
在一种实施例中，如图4所示，所述第三狭缝317还包括第六狭缝314和第七狭缝316，所述第六狭缝314位于所述第二象限区域412，所述第七狭缝316位于所述第四象限区域414，所述第六狭缝314和所述第七狭缝316的中心线处于同一直线上，且穿过所述重合区域，所述第六狭缝314和所述第七狭缝316与所述重合区域不接触；在设置第三狭缝时，通过在第二象限区域和第四象限区域分别形成第六狭缝和第七狭缝，使得第六狭缝和第七狭缝可以分别将第二象限区域和第四象限区域中的像素电极划分为多个子像素电极，而由于多个狭缝的存在，使得液晶方向的数量增加，从而使得在沿第二象限区域至第四象限区域的方向，或者第四象限区域至第二象限区域的方向观看时，由于液晶方向的数量增大，相对于现有液晶方向数量较少，使得在该方向观看时，该方向的亮度可以分散，从而可以改善色偏，提高液晶显示面板的视角。
在一种实施例中，所述第六狭缝和第七狭缝分别包括一条狭缝，所述第六狭缝将所述第二象限区域的像素电极划分为两个子像素电极，所述第七狭缝将所述第四象限区域的像素电极划分为两个子像素电极，在对第六狭缝和第七狭缝进行设置时，可以使得第六狭缝和第七狭缝仅包括一条狭缝，从而将第二象限区域和第四象限区域的像素电极分别划分为两个子像素电极，从而相应的增加了液晶的方向，改善色偏，缓解现有垂直配向型液晶显示器件的大视角色偏。
在一种实施例中，如图4所示，所述第六狭缝314和第七狭缝316分别包括三条狭缝，所述第六狭缝314将所述第二象限区域412的像素电极218划分为四个子像素电极，所述第七狭缝316将所述第四象限区域414的像素电极218划分为四个子像素电极，在第六狭缝和第七狭缝将分别将第二象限区域和第四象限区域的像素电极划分为多个子像素电极时，可以将各个象限区域的像素电极划分为4等分、8等分，可以将像素电极划分为各个数量的子像素电极，从而相应的得到各个畴的子像素，相应提高液晶方向的数量，从而相应的增加改善色偏的能力，从而提高液晶显示面板的视角，缓解现有垂直配向型液晶显示器件存在大视角色偏的技术问题。
在一种实施例中，所述第三狭缝包括第四狭缝和第五狭缝，所述第四狭缝位于所述第一象限区域，所述第五狭缝位于所述第三象限区域，所述第四狭缝与所述第五狭缝形成的重合区域、与所述第一狭缝和第二狭缝形成的重合区域相同；在设置第四狭缝和第五狭缝时，还可以将第四狭缝和第五狭缝形成重合区域，从而提高开口率，且第四狭缝与第五狭缝与第一狭缝和第二狭缝形成的重合区域相同，从而将各个象限区域的像素电极等分。
在一种实施例中，所述第三狭缝还包括第六狭缝和第七狭缝，所述第六狭缝位于所述第二象限区域，所述第七狭缝位于所述第四象限区域，所述第六狭缝和所述第七狭缝的形成的重合区域、与所述第一狭缝和第二狭缝形成的重合区域相同；在设置第六狭缝和第七狭缝时，第六狭缝和第七狭缝形成重合区域，从而提高开口率，且第六狭缝和第七狭缝形成的重合区域与第一狭缝和第二狭缝形成的重合区域相同，使得第六狭缝和第七狭缝将各个象限区域的像素电极等分。
在一种实施例中，所述第一狭缝、所述第二狭缝、所述第四狭缝、所述第五狭缝、所述第六狭缝、所述第七狭缝中各个狭缝的长度相等、宽度相等，在设置各个狭缝时，使得各个狭缝的长度和宽度相等，从而使得各个方向的狭缝中的液晶量一致，从而避免由于液晶量的不同导致的显示亮度不同，从而改善色偏。
在一种实施例中，所述第一狭缝与所述像素电极形成的圆形的边缘之间的间距范围、等于所述像素电极的直径的十分之一至五分之一；在设计第一狭缝时，为了提高开口率，应该使得第一狭缝的长度尽量大，但考虑到像素电极的边缘连接的部分较窄，会出现断裂的问题，导致像素电极的各个子像素电极之间无信号，因此，像素电极的边缘的连通的部分应该具有一定的宽度，可以使得第一狭缝距离像素电极的边缘一定的间距，例如将第一狭缝的一端与像素电极的边缘之间的最小间距范围设置为像素电极的直径的十分之一至五分之一，使得第一开口尽量较大，同时，使得像素电极的边缘的连接部分存在一定的宽度，从而使得液晶显示面板正常工作时，液晶显示面板的开口率提高。
在一种实施例中，如图4所示，所述薄膜晶体管包括数据线216和扫描线214，所述数据线216和所述扫描线214设置于所述子像素201形成的正方形的边上，所述像素电极218与所述扫描线214之间的间距等于所述扫描线214的线宽，在设置子像素时，将数据线和扫描线设置在子像素的边上，使得在形成圆形的像素电极时，通过在子像素的边上形成扫描线和数据线，充分利用子像素的空间，同时，为了提高开口率，可以使得扫描线与像素电极之间的间距尽量较小，但为了避免各个走线之间出现寄生电容，将扫描线与像素电极之间相隔一定的距离，可以使得像素电极与扫描线之间的间距等于扫描线的线宽，从而尽量提高开口率，且使得液晶显示面板正常工作。
在一种实施例中，如图3、图4所示，所述液晶显示面板还包括公共电极层232和衬底211，所述公共电极层232在所述衬底211上的投影围绕所述像素电极218设置，且相邻子像素201中的公共电极层232通过公共电极走线连接，在公共电极层的设计时，也可以使得公共电极层设计为圆形，然后通过公共电极走线将公共电极层连接，从而使得公共电极层的信号相同。
在一种实施例中，如图3所示，液晶显示面板包括COA（Color On Array，彩膜层设置在阵列侧）基板、第一基板、以及设置于所述COA基板与所述第一基板之间的液晶层22，所述COA基板包括衬底211、栅极层214、栅极绝缘层213、有源层212、层间绝缘层215、源漏极层216、色阻层234、平坦化层217、像素电极层218，所述第一基板包括公共电极层232、黑色矩阵层233、基板235，所述栅极层图案化形成有栅极和扫描线、所述源漏极层图案化形成有源漏极和数据线，所述像素电极层图案化形成有像素电极。
如图2、图5所示，现有液晶显示面板中的液晶方向和本申请实施例中液晶显示面板的方向对比，可以看出本申请实施例中的液晶22的方向包括垂直方向、水平方向、斜向，以45度角观看液晶显示面板为例，在现有液晶显示面板中，由于液晶方向为45度角、135度角、225度角、315度角，使得在45度观看时，大量的液晶设置在45度角和225度角方向，导致亮度较大，出现色偏，而在本申请实施例中的液晶显示面板中，在45度角观看液晶显示面板时，由于液晶分散到垂直方向、水平方向和45度角方向，导致亮度降低，从而改善色偏。
如图4、图6所示，本申请实施例提供一种液晶显示装置，该液晶显示装置包括液晶显示面板和背光模组5，所述液晶显示面板包括多个子像素201，所述子像素201包括像素电极218和薄膜晶体管，所述子像素201的形状包括正方形，所述像素电极218的形状包括圆形，所述薄膜晶体管设置于所述子像素201形成的正方形的各条边上，并通过信号线与所述像素电极218连接；
