【技术领域】
本发明涉及显示技术领域，特别是涉及一种像素电极结构及液晶显示装置。
【背景技术】
液晶显示器（LCD，liquid Crystal Display）是最广泛使用的平板显示器之一，实现其图像显示有多种模式，如TN（twisted nematic liquid crystal，扭曲向列型液晶）模式、IPS（In Plane Switching liquid crystal，平面内切换液晶）模式以及VA（Vertical Alignment liquid crystal，垂直排列液晶）模式。
HVA作为液晶VA模式中的一种分支模式，其采用光配向加电的方式，实现在PI表层固化出具有一定预倾角的液晶层，以省略传统摩擦取向。
为实现液晶显示的广视角，HVA模式中的像素电极采用多区域（Muti-Domain）的结构，图1为现有技术HVA模式中像素电极结构100的结构示意图。如图1所示，主干电极101垂直设置，主干电极102水平设置，并且主干电极101和主干电极102的中心垂直相交，以形成11、12、13以及14四个显示区域，在每个显示区域中设置有多条分支电极，如图1所示的分支电极111、121、131以及141。并且主干电极101、102以及分支电极111、121、131以及141的尾端的边界均齐平。
但是，主干电极101以及主干电极102的尾端的电场与显示区域内分支电极111、121、131以及141之间的电场的场型存在差异，因此，会导致主干电极101以及主干电极102尾端的液晶指向紊乱，产生错向（disclination），从而影响主干电极尾端的显示品质和穿透率。
【发明内容】

【具体实施方式】
下面结合附图和实施例对本发明进行详细说明。
请参考图2，图2是本发明像素电极结构第一实施例的结构示意图，如图2所示，本发明的像素电极结构200包括两条状的主干电极，其中，该条状主干电极包括第一主干电极201以及第二主干电极202。
本实施例中，第一主干电极201竖直设置，第二主干电极202水平设置，并且第一主干电极201的中心与第二主干电极202的中心垂直相交，以形成四个显示区域，如图2中的显示区域21、22、23以及24。其中，在四个显示区域21、22、23以及24中分别间隔设置有多条条状的分支电极，且多条分支电极的尾端的边界齐平，而主干电极的尾端的边界与分支电极的尾端的边界不齐平。具体地：
以显示区域21的设置为例说明。在显示区域21中间隔设置多条条状的分支电极211，每相邻的两分支电极211之间设置有刻缝212，并且多条分支电极211以及多条刻缝212均相互平行。其中，分支电极211的一端与第一主干电极201或者第二主干电极202相连，另一端向显示区域21的外侧延伸，并且分支电极211的尾端的边界齐平。
其中，显示区域22中的分支电极221、显示区域23中的分支电极231以及显示区域24中的分支电极241的设置与分支电极211的设置相同，在此不再赘述。
承前所述，分支电极211、221、231以及241与第一主干电极201以及第二主干电极202形成一个“米”字结构。在该“米”字结构中，设置主干电极的尾端的边界与分支电极的尾端的边界不齐平，以此减小主干电极的尾端与分支电极之间存在电场场型的差异。具体以第二主干电极202中的其中一个尾端举例说明：
第二主干电极202的尾端203的边界相对于分支电极211以及241在垂直方向的尾端的边界向外凸出，其向外凸出的延伸部为条状的附加电极210，且附加电极210沿着平行于第二主干电极202的方向延伸。本实施例中，附加电极210的宽度优选为与第二主干电极202的宽度相同。
其中，第一主干电极201的两尾端与第二主干电极202的另一尾端的设置与上述的第二主干电极202的尾端203的设置方法相同，在此不再赘述。
本实施例中，设置主干电极的尾端向外凸出附加电极210，使得主干电极的尾端的边界与分支电极的尾端的边界不齐平，从而减小了主干电极尾端的电场与分支电极的电场的场型差异，使得主干电极尾端的液晶指向正常，因此提高了主干电极尾端的显示品质，具体请参考图3所示的效果。
请一并参考图3和图4，图3是本发明一种像素电极结构第一实施例的效果图，图4是现有技术的像素电极结构的效果图。如图3所示，像素电极结构200对应的效果图分为四个显示区域显示，每个显示区域之间由主干电极对应的“黑色区域”隔开。其中，第一主干电极201的尾端和第二主干电极202的尾端均向外凸出显示，并且均为两凸出显示区，两凸出显示区之间由主干电极对应的“黑色区域”隔开。而图4所示的现有技术中的第一主干电极101和第二主干电极102的尾端均出现“黑色区域”。因此，图3中的显示效果明显改善了主干电极尾端的显示品质。
请参考图5，图5是本发明一种像素电极结构第二实施例的结构示意图，如图5所示，本发明的像素电极结构300同样为“米”字形结构，其与图2所示的像素电极结构200的不同之处在于：图5所示的主干电极的尾端向外凸出的延伸部为一对条状的附加电极。具体以第二主干电极302的其中一尾端具体说明。
第二主干电极302的尾端303向外突出的延伸部为一对条状的附加电极310，且附加电极310中的一个附加分支电极与其所在的显示区域31中的分支电极311平行，另一个附加分支电极与其所在的显示区域34中的分支电极341平行。其中，附加电极310中的附加分支电极小于显示区域中的任一分支电极。
其中，第一主干电极301的两尾端以及第二主干电极302的另一尾端的设置与上述的第二主干电极302的尾端303的设置相同，在此不再赘述。
同理，本实施例中的条状的附加电极同样改善了主干电极尾端的显示品质，具体请参考图6所示的效果。
请一并请参考图4和图6，图6是本发明一种像素电极结构第二实施例的效果图，如图6所示，第一主干电极301的尾端和第二主干电极302的尾端均向外凸出显示。而图4所示的第一主干电极101和第二主干电极102的尾端均出现“黑色区域”。因此，图6中的显示效果明显改善了主干电极尾端的显示品质。
请参考图7，图7是本发明一种像素电极结构第三实施例的结构示意图，如图7所示，本发明的像素电极结构400同样为“米”字形结构，其与图2所示的像素电极结构200的不同之处在于：图7所示的主干电极的尾端的向外凸出的延伸部为梯形的附加电极。具体以第二主干电极402的其中一尾端具体说明。
第二主干电极402的尾端403的向外凸出的延伸部为梯形的附加电极410，并且两侧边均与第二主干电极402相连，其中一个侧边与显示区域41中的分支电极411平行，另一个侧边与显示区域44中的分支电极441平行。其中梯形附加电极410的顶边的宽度优选为与第二主干电极402的宽度相同。
其中，第一主干电极401的两尾端以及第二主干电极402的另一尾端的设置与上述的第二主干电极402的尾端403的设置相同，在此不再赘述。
同理，本实施例中的梯形的附加电极同样改善了主干电极尾端的显示品质，具体请参考图8所示的效果。
图8是本实施例中像素电极结构第三实施例的效果图，如图8所示，第一主干电极401的尾端和第二主干电极402的尾端均向外凸出显示。与现有技术的图4所示的第一主干电极101和第二主干电极102的尾端均出现“黑色区域”的效果相比，图8中的显示效果明显改善了主干电极尾端的显示品质。
承前所述，以上实施例所述的主干电极的尾端边界与分支电极的尾端边界不齐平的情况均是主干电极的尾端的边界相对于分支电极的尾端的边界向外凸出。在其他实施例中，本发明提供了另一种情况：
主干电极的尾端的边界相对于分支电极的尾端的边界向内凹陷，其同样可以改善主干电极的尾端显示不良的现象。
请参考图9，图9是本发明一种像素电极结构第四实施例的结构示意图。如图9所示，本发明的像素电极结构500依然为“米”字形结构，其与图2所示的像素电极结构200的不同之处在于：本发明的像素电极结构500的主干电极的尾端向内凹陷，并且凹陷部为梯形结构。具体以第二主干电极502的其中一尾端举例说明。
第二主干电极502的尾端503的边界相对于分支电极511以及541在垂直方向的尾端的边界向内凹陷，并且凹陷部为一梯形结构510。其中梯形结构510的其中一侧边与显示区域51中的分支电极511平行，另一侧边与显示区域54中的分支电极541平行。
在其他实施例中，凹陷部还可以是其他结构，例如图10所示的三角形结构，在图10所示的像素电极结构600中，第一主干电极601的尾端以及第二主干电极602的尾端的凹陷部为三角形结构。
在其他实施例中，本发明还可以设置主干电极的尾端的边界与分支电极的尾端的边界齐平，并且主干电极的尾端变细，以此达到改善主干电极尾端的显示品质。
承前所述，上述实施例中的主干电极的尾端结构其均能独立改善主干电极尾端的显示品质，因此，可以理解的是在同一个像素电极结构中，其主干电极的尾端可以任意搭配上述实施例中的主干电极的尾端结构，以改善主干电极尾端的显示品质。
本发明还提供了一种液晶显示装置，其包括图2至图10所示的任一实施例的像素电极结构。
综上所述，本发明通过设置主干电极的尾端的边界与分支电极的尾端的边界不齐平，使得主干电极尾端的电场与显示区域中的分支电极的电场的场型差异变小，从而使得主干电极的尾端的液晶指向正常，因此改善了主干电极尾端的显示品质，进一步改善了液晶显示装置的显示品质。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
