目前，液晶面板按照显示模式可以分为：扭曲向列(TN，Twisted Nematic)型、平面转换(IPS，In Plane Switching)型和高级超维场开关(Advanced Super Dimension Switch，ADSDS，简称ADS)型等。其中，ADS显示模式的液晶面板是通过同一平面内电极边缘所产生的电场以及电极层与板状电极层间产生的电场形成多维电场，使在电极之间和电极正上方的所有液晶分子发生旋转，相对于IPS显示模式的液晶面板，能够提高液晶的工作效率且增加了透光效率。ADS显示模式的液晶面板具有高画面品质、高分辨率、高透过率、低功耗、宽视角、高开口率、低色差、无水波纹(push Mura)等优点。
如图1为现有技术ADS显示模式的显示面板中，同一电极层上的电极排列形式结构示意图。其中，在一像素区内设定两个附属区1和2，附属区1和2中分别设有电极70，其设置为平行电极。在附属区1和2内的电极70相互成90度倾斜角度，且在各自方向上延伸，利用电极70之间的电压产生与电极70垂直的电场E1以激励液晶分子21。
为避免存在液晶层的折射率各向异性及液晶厚度随视角倾斜角度变化而变化的问题，通常使附属区1和2中的液晶分子21初始取向相差90度，当在液晶显示装置施加一电压时，液晶分子21以相同的方向旋转，但转动后的 取向保持相互90的间隔，如图2所示。
然而，上述图1结构的共面液晶显示装置中，在施加转向电压前，液晶层的液晶分子受显示装置上所贴附取向膜的影响，分别处于初始取向，附属区1和2内的液晶分子相差90度；然而，在附属区1和2的区域边界处，如图2所示，由于区域边界处的液晶分子受附属区1和2所对应不同角度取向膜的影响，存在区域边界处的液晶分子取向不确定的问题，在区域边界处从附属区1内的取向过渡到附属区2内的取向时，可能朝向不同方向转动，因此产生图3所示区域边界处的“向错点”(在图3中用“×”表示)，引起显示器亮度不均匀，造成mura现象；尤其当“向错点”处于特定位置或者呈现不均匀时，对显示器的亮度影响更为明显。

具体实施方式
为使本公开文本的目的、技术方案和优点更加清楚，下面将结合附图及具体实施例对本公开文本进行详细描述。
本公开文本一实施方式的显示面板包括第一基板、第二基板、设置于所述第一基板与所述第二基板之间的液晶层，其中所述第一基板或所述第二基 板上形成有像素单元，所述像素单元包括第一子单元区域和第二子单元区域，所述第一子单元区域所对应液晶层的液晶分子具有第一初始取向，所述第二子单元区域所对应液晶层的液晶分子具有第二初始取向，其中所述像素单元还包括：位于所述第一子单元区域和所述第二子单元区域之间的第三子单元区域，所述第三子单元区域所对应液晶层的液晶分子具有第三初始取向，所述第三初始取向为从所述第一初始取向沿第一旋转方向朝所述第二初始取向转动时的其中一取向，所述第一初始取向与所述第二初始取向之间的角度差值大于0度且小于等于90度。
如图4所示，采用本公开文本所述显示面板，位于第一子单元区域1和第二子单元区域2之间的第三子单元区域3所对应液晶层的液晶分子具有第三初始取向，其为从第一初始取向沿第一旋转方向朝第二初始取向转动时的其中一取向。本公开文本中第一初始取向与第二初始取向之间的角度差值大于0度且小于等于90度，通常第一初始取向与所述第二初始取向互为垂直。例如，当设定第二初始取向的方向为水平方向，也即为0度时，第一初始取向则为90度；此时，第三初始取向为从90度沿顺时针方向转动至0度时的任一取向，也可以为从90度沿逆时针方向转动至0度时的任一取向，摩擦方向统一，保证预定范围内不会产生向错点问题。
本公开文本实施例中的“初始取向”为液晶分子在未加电状态时的摩擦方向。此外，第一旋转方向为顺时针方向或逆时针方向，也即只能取顺时针方向和逆时针方向的其中之一方向。
具体地，第三子单元区域3内的液晶分子可以具有不统一的摩擦方向，如图4所示。所述第三子单元区域3包括用于划分第一子单元区域1与第三子单元区域3的第一边界31和用于划分第二子单元区域2与第三子单元区域3的第二边界32。其中，在所述第三子单元区域3内，与所述第一边界31的距离不同的区域对应的液晶分子所具有的所述第三初始取向不同；例如，从所述第一边界31至所述第二边界32，所述第三初始取向从所述第一初始取向沿第一旋转方向朝所述第二初始取向转动逐渐变化。
上述的“第一边界31”和“第二边界32”是分别用于区分第一子单元区域1与第三子单元区域3、第二子单元区域2与第三子单元区域3的界限， 也即在第一边界31和第二边界32两侧的液晶分子，初始取向不同。在第三子单元区域3内，第一边界31位置处的液晶分子的初始取向相较于第一子单元区域1的液晶分子的初始取向发生变化。在第三子单元区域3内，第二边界32位置处的液晶分子的初始取向相较于第二子单元区域2的液晶分子的初始取向发生变化。其中，在第三子单元区域3内，液晶分子具有第三初始取向，从第一边界31位置处至第二边界32位置处，随着与第一边界31之间距离不同的变化第三初始取向发生变化，例如，从所述第一初始取向沿第一旋转方向朝所述第二初始取向转动逐渐变化；也即在第一边界31位置处第三初始取向较接近于第一初始取向，在第二边界32位置处第三初始取向较接近于第二初始取向。例如，结合图4来说，在第三子单元区域3内，从第一边界31至第二边界32，液晶分子的第三初始取向从接近于第一初始取向的状态向接近于第二初始取向的状态逐渐变化，与第二初始取向之间所成的锐角逐渐变小。
在本公开文本中，所提及的液晶分子的“取向”是指液晶分子长轴的方向。以下结合具体实施例对本公开文本所述显示面板的结构进行详细描述。
第一实施例：
图5为本公开文本一实施方式的显示面板的结构示意图。所述显示面板包括第一基板100、第二基板200、依次于第一基板100与第二基板200之间设置排列的彩膜300、第一取向膜400、液晶层500和第二取向膜600。其中，在第二基板200上设置有第一电极层701和第二电极层702，第一电极层701与第二电极层702之间为绝缘层。其中第一电极层701由多个条状的电极构成。
另外，第二基板200上还设置有包括多个相互平行设置的栅极线和多个相互平行设置的数据线，且栅极线与数据线相交叉，共同围绕形成多个像素单元。如图6所示，每一像素单元由相互平行的两条栅极线730和相互平行的两条数据线740构成。每一像素单元包括两个子单元，每一子单元对应一个电极区域如第一电极区域750或第二电极区域760；其中，第一电极区域750内具有条状的第一电极711，第一电极711相互平行并具有第一延伸方向；第二电极区域760内具有条状的第二电极712，第二电极712相互平行并具 有第二延伸方向，而且第二延伸方向与第一延伸方向相垂直。
所述液晶层500的第一取向膜400和第二取向膜600的表面被处理，以用于当液晶层500上的液晶分子未施加电场时，使液晶层500内的液晶分子被定向。所述第一取向膜400和第二取向膜600的结构均如图7所示，所述第一取向膜400和第二取向膜600分别包括第一取向区域10和第二取向区域20。所述第一取向区域10具有第一摩擦方向，所述第二取向区域20具有第二摩擦方向。
结合图8，所述第三子单元区域3包括第一部分311和第二部分312；第一部分311为邻近第一子单元区域1的部分，第二部分312为邻近第二子单元区域2的部分。所述第一取向区域10除包括对应所述第一子单元区域1的部分外，还包括与所述第三子单元区域3的第一部分311对应的部分，所述第二取向区域20除包括对应第二子单元区域2的部分外，还包括与第三子单元区域3的第二部分312对应的部分。
此外，所述第一取向区域10具有第一摩擦方向使第一子单元区域1对应的液晶分子在未施加电场时具有所述第一初始取向，所述第二取向区域20具有第二摩擦方向使所述第二子单元区域2对应的液晶分子在未施加电场时具有所述第二初始取向。本领域技术人员可以理解，液晶层内液晶分子的初始方向是依据取向膜的摩擦方向被定位，通常情况下，初始方向与取向膜的摩擦方向所对应，也即当取向膜的摩擦方向为90度时，被定位的液晶分子的初始取向则为90度；当取向膜的摩擦方向为0度时，被定位的液晶分子的初始取向方向则为0度。因此，液晶层500在第一子单元区域1的第一初始取向等于第一取向区域10所具有的第一摩擦方向，液晶层500在第二子单元区域2的第二初始取向等于第二取向区域20所具有的第二摩擦方向。
因此，所述第一初始取向与所述第一摩擦方向相同，所述第二初始取向与所述第二摩擦方向相同。
本公开文本所述显示面板的第一实施例，为避免第一子单元区域1和第二子单元区域2之间产生“向错点”，所述第一摩擦方向与所述第二摩擦方向之间的夹角大于0度且小于90度，可选地，第一摩擦方向与第二摩擦方向之间的角度差值大于88度。根据取向膜的上述设置方式，被定向的液晶层500 内，与像素单元的两个子单元区域对应的液晶分子，初始取向之间的差值小于90度，能够达到避免两个子单元区域之间在预定区域范围内产生“向错点”的效果。
结合图8所示液晶分子的状态示意图，采用本公开文本第一实施例的所述显示面板，由于第一摩擦方向与第二摩擦方向的夹角大于0度小于90度，因此第一初始取向与第二初始取向之间的夹角也大于0度小于90度，可选地，第一摩擦方向与所述第二摩擦方向之间所夹的锐角大于88度。具体的，第一摩擦方向相对于水平延伸方向呈89.8度，所述第二摩擦方向相对于水平延伸方向呈0.2度；对应的，第一初始取向相对于水平延伸方向之间的角度α为89.8度，第二初始取向相对于水平延伸方向之间的角度β为0.2度，基于以上取向角度数值，在第一子单元区域1与第二子单元区域2之间交界处的液晶分子，当在取向膜的作用下，由第一初始取向转动到第二初始取向时，由于朝第一旋转方向回转，如图9所示的顺时针方向时，所经历的角度变化为：89.8》80》70》...》10》0.2，需要回转89.6度，而朝第二方向回转，如图9所示的逆时针方向时，所经历的角度变化为：89.8》100》110》...》180.2(＝0.2)，需要回转90.4度，第一种回转方式的转动角度小于第二种回转方式的转动角度，转动所需能量较小，且所形成边界更稳定，因此在该种状态下发生第一种回转方式的概率远远大于发生第二种回转方式的概率，使处于第一子单元区域1和第二子单元区域2的区域边界处的液晶分子统一以一种回转方式进行取向，避免预定区域范围内“向错点”的产生。
根据以上，采用本公开文本第一实施例所述显示面板，第一子单元区域1和第二子单元区域2内液晶分子在未加电时的初始取向形成为图8所示形式，α与β之间的角度差值小于90度。由于所述第一初始取向与取向膜第一取向区域10所具备的第一摩擦方向相同，第二初始取向与取向膜第二取向区域20所具备的第二摩擦方向相同，因此所述第一摩擦方向与所述第二摩擦方向之间所夹的锐角大于0度且小于90度，最佳地，所述第一摩擦方向与所述第二摩擦方向之间所夹的锐角大于88度。
基于以上，第三子单元区域3内液晶分子所具有的第三初始取向与第一初始取向、第二初始取向分别不同，且第三初始取向与第一初始取向、第二 初始取向之间的角度差值小于90度大于0度。
此外，由于第三子单元区域3的第一部分311与取向膜的第一取向区域10对应，第二部分312与取向膜的第二取向区域20对应，在取向膜的第一摩擦方向和第二摩擦方向的共同作用下，第三子单元区域3所对应液晶分子具有第三初始取向，从与第一子单元区域1的第一边界31至与第二子单元区域2的第二边界32，第三初始取向从第一初始取向沿第一旋转方向朝第二初始取向转动逐渐变化。
也即，当第一初始取向具备相对于第一标准取向(90度)朝一方向偏转第一角度的延伸方向时，则使第二初始取向具备相对于第二标准取向(0度)朝相反方向偏转第二角度的延伸方向，其中第一角度与第二角度均小于1度，第一标准取向与第二标准取向互为90度。因此，采用本公开文本上述结构使液晶层一个像素结构内的液晶分子形成为图4所示状态，位于第一子单元区域1与第二子单元区域2之间交界处的液晶分子，在取向膜的作用下，会朝一个方向进行回转取向，避免预定区域范围内产生“向错点”。
采用该种设置方式，通过使第一取向膜400和第二取向膜600中第一取向区域10与第二取向区域20上摩擦方向的角度差值小于90度，并大于等于88度，液晶层500的第三子单元区域3在第一取向区域10和第二取向区域20的摩擦方向作用下，统一以一种回转方式进行取向，避免预定区域如第三子单元区域3范围内“向错点”的产生，解决现有技术显示装置由于“向错点”造成显示亮度不均的问题。
另外，需要进一步说明的是，通常情况下取向膜的作用是使对应的液晶分子按照取向膜的摩擦方向进行初始取向，但在实际中，受各种因素影响，液晶分子初始取向可能会与摩擦方向之间存在一定的偏差。基于此，本公开文本上述以及以下所有实施例中提到的初始取向和摩擦方向相同都是近似相同，允许有一定的偏差。
第二实施例：
本公开文本中，为进一步保证两个子单元区域之间的预定区域范围内不会产生“向错点”，本公开文本还提供第二实施例的显示面板。
在第二实施例中，显示面板的结构参阅图5所示，与第一实施例相同， 包括第一基板100、第二基板200、依次于第一基板100与第二基板200之间设置排列的彩膜300、第一取向膜400、液晶层500和第二取向膜600。
结合图10，其中第一取向膜400和第二取向膜600分别包括与第一子单元区域1对应的第一取向区域10和与第二子单元区域2对应的第二取向区域20。所述第一取向区域10具有第一摩擦方向使第一子单元区域1所对应的液晶分子在未施加电场时的指向在所述第一初始取向。所述第二取向区域20具有第二摩擦方向使所述第二子单元区域2所对应的液晶分子在未施加电场时的指向在所述第二初始取向。
具体地，第一取向膜400和第二取向膜600，用于使对应的液晶分子按取向膜的摩擦方向进行初始取向，第一子单元区域1的第一初始取向等于第一取向区域10所具有的第一摩擦方向，第二子单元区域2的第二初始取向等于第二取向区域20所具有的第二摩擦方向。可选地，第一摩擦方向与第二摩擦方向之间的夹角等于90度。
本公开文本第二实施例中，进一步地，第一取向膜400和第二取向膜600还分别包括第三取向区域30。第三取向区域30设置于第一取向区域10与第二取向区域20之间，并与第三子单元区域3对应。该第三区域30具有第三摩擦方向使第三子单元区域3所对应的液晶分子在未施加电场时的指向在第三初始取向。所述第三摩擦方向与所述第一摩擦方向、所述第二摩擦方向都不同，该第三初始取向方向为从所述第一初始取向沿第一旋转方向朝所述第二初始取向转动时的其中一取向。这样，通过取向膜的取向区域在摩擦方向上的改进，使第三子单元区域3的液晶分子具有如图4所示的初始取向，进而可解决向错点问题。
本公开文本第二实施例中，当第一摩擦方向相对于一水平延伸方向呈90度，第二摩擦方向相对于水平延伸方向呈0度时，该第三摩擦方向可以为处于从0度沿顺时针或逆时针转动至90度之间的方向，如相对于水平延伸方向呈45度或-45度，也即所述第三摩擦方向与所述第一摩擦方向或所述第二摩擦方向之间的夹角为45度。
本公开文本第二实施例，通过对第一取向膜400和第二取向膜600对应第一子单元区域1和第二子单元区域2之间交界处的区域如第三子单元区域 3进行特定方向的取向处理，使液晶层500上第一子单元区域1和第二子单元区域2的交界区域如第三子单元区域3处的液晶分子均匀排列，达到进一步保证避免“向错点”产生的问题。
当然，在第二实施例中，第一取向膜400和第二取向膜600在第一取向区域10和第二取向区域20的摩擦方向，也可以结合第一实施例的结构设置，也即使第一摩擦方向与第二摩擦方向之间的差值小于90度且大于88度，如第一摩擦方向相对于一水平延伸方向呈89.8度，第二摩擦方向相对于水平延伸方向呈0.2度，更能够有效保证避免预定区域范围内“向错点”产生的问题。
采用上述第一实施例和第二实施例的显示面板，通过改进取向膜的结构，能够保证液晶层在未加电场的情况下，两个区域之间的交界区域处在预定区域范围内不会产生“向错点”；此外，本公开文本还通过改进取向膜与电极之间的设置关系，进一步保证液晶层在加电和不加电情况下，预定区域范围内均不会由于液晶分子逆回转产生“向错点”。
第三实施例：
因此，本公开文本还提供第三实施例的显示面板，在第三实施例中，显示面板的具体结构与第一实施例和第二实施例相同，结合图5，包括第一基板100、第二基板200，以及依次于第一基板100与第二基板200之间设置排列的彩膜300、第一取向膜400、液晶层500和第二取向膜600。
其中，第二基板200上形成有像素单元，该像素单元包括三个区域，对应在所述液晶层500上形成为液晶分子在未加电场时具有第一初始取向的第一子单元区域1、具有第二初始取向的第二子单元区域2和具有第三初始取向的第三子单元区域3，具体结合图4所示。
其中，第一初始取向与第二初始取向之间的角度差值可以为等于90度，也可以为小于90，大于等于88度。
此外，在第三实施例中，还对第二基板200上电极的排列形式以及取向膜的摩擦方向进行了改进。结合图11与图5，在所述第二基板200中，所述第一电极层701包括第一电极区域750、第二电极区域760和第三电极区域770，其中：
第一电极区域750中设置有多个平行排列、具有第一延伸方向的第一电极711；
第二电极区域760中设置有多个平行排列、具有第二延伸方向的第二电极712；
第三电极区域770中设置有多个平行排列、具有第三延伸方向的第三电极713；所述第三电极区域770位于所述第一电极区域750与所述第二电极区域760之间。
在本公开文本第三实施例中，上述的第一延伸方向与第二延伸方向不同，且第一延伸方向与第二延伸方向之间所夹的锐角大于0度且小于等于90度，可选地为等于90度。此外，第三延伸方向与第一延伸方向相同，且每一第三电极713与一个第一电极711连接。此外，如图11所示，第一电极711、第二电极712与第三电极713的连接方式可以是三者相互电连接，或者分别连接导线，输入相应的信号。
进一步，所述显示面板还包括：
设置于液晶层500两侧的第一取向膜400和第二取向膜600。其中第一取向膜400和第二取向膜600分别包括：
具有第一摩擦方向的第一取向区域10和具有第二摩擦方向的第二取向区域20。
结合图11，在第三实施例中，所述第一取向区域10对应所述第一电极区域750，所述第二取向区域20对应所述第二电极区域760和第三电极区域770的组合区域。
可选地，所述第一摩擦方向与所述第二摩擦方向之间的角度差值为90度，且所述第一摩擦方向与所述第一延伸方向之间所夹的锐角为3度至25度，所述第二摩擦方向与所述第二延伸方向之间所夹的锐角为3度至25度，使得液晶分子在电场作用下能够更好的偏转，以提高显示面板的透过率。
利用图11所示取向膜与电极之间的设置关系，当对各电极区域的电极施加电场并撤销所施加电场后，在电场与取向膜的共同作用下，如图12并结合图5，液晶层500的液晶分子形成为第一子单元区域1、第二子单元区域2和第三子单元区域3，其中第一子单元区域1和第二子单元区域2内液晶分子 分别为第一初始取向和第二初始取向，第三子单元区域3具有第三初始取向，该第三初始取向为从所述第一初始取向沿第一旋转方向朝所述第二初始取向转动时的其中一取向。因此，结合图11、图12，所述第一子单元区域1对应所述第一电极区域750的第一部分，所述第三子单元区域3对应所述第一电极区域750的第二部分和所述第三电极区域770的组合区域，所述第二子单元区域2对应所述第二电极区域760。所述第一电极区域750的第一部分与所述第一电极区域750的第二部分组合形成为所述第一电极区域750，所述第一电极区域750的第二部分与所述第三电极区域770相邻设置。上述第一初始取向与第一摩擦方向是相同的，第二初始取向与第二摩擦方向是相同的。具体的，在图12中，第一摩擦方向和第二摩擦方向是相互垂直的关系，即第一初始取向和第二初始取向也是相互垂直的。
基于图12所形成的初始状态，当在加电情况下，形成为如图13所示结构，第一子单元区域1内的液晶分子具有第一方向，第二子单元区域2内的液晶分子具有第二方向，第三子单元区域3内的液晶分子具有第三方向，且第三方向为从所述第一方向沿所述第一旋转方向朝所述第二方向转动时的其中一方向。结合图11、图12与图13，在加电情况下，第一子单元区域1与第三子单元区域3上所施加电场相同，但由于液晶分子的初始取向不同，形成为如图13所示加电后的状态。
通过第三实施例的结构，取向膜交界区域如对应第三子单元区域3的区域的液晶分子在电场作用下有规则排列，进而可以解决加电后该部分区域出现的向错点问题。
第四实施例
此外，本公开文本还提供第四实施例的显示面板，在第四实施例中，
与第三实施例相同，所述阵列基板中，结合图5与图14，所述第一电极层701包括第一电极区域750、第二电极区域760和第三电极区域770，其中：
第一电极区域750中设置有多个平行排列、具有第一延伸方向的第一电极711；
第二电极区域760中设置有多个平行排列、具有第二延伸方向的第二电极712；
第三电极区域770中设置有多个平行排列、具有第三延伸方向的第三电极713；所述第三电极区域770位于所述第一电极区域750与所述第二电极区域760之间；上述的第一延伸方向与第二延伸方向不同，且第一延伸方向与第二延伸方向之间的角度差值大于0度且小于等于90度，可选地为等于90度。此外，结合图5，所述显示面板还包括：
设置于液晶层500两侧的第一取向膜400和第二取向膜600。其中第一取向膜400和第二取向膜600分别包括：
具有第一摩擦方向的第一取向区域10和具有第二摩擦方向的第二取向区域20；可选地，所述第一摩擦方向与所述第二摩擦方向之间的角度差值为90度。
与第三实施例不同，第四实施例中，所述第三延伸方向与所述第一延伸方向不同。可选地，每一第一电极711与一个第三电极713连接；所述第三延伸方向与水平延伸方向之间的锐角角度小于所述第一延伸方向与水平延伸方向之间的锐角角度，可选地在0度至45度范围之间，使第三子单元区域3的液晶分子在电场作用下能够更加规则的取向，更好地消除向错点问题。此外，如图14所示，第一电极711、第二电极712与第三电极713的连接方式可以是三者相互电连接，或者三者分别连接导线，输入相应的信号。
此外，第一取向区域10对应所述第一电极区域750，所述第二取向区域20对应所述第二电极区域750和所述第三电极区域760的组合区。所述第一取向区域10所具有的第一摩擦方向与所述第一延伸方向之间所夹的锐角为3度至25度，所述第二取向区域20所具有的第二摩擦方向与所述第二延伸方向之间所夹的锐角为3度至25度。
利用图14所示取向膜与电极之间的设置关系，当对各电极区域的电极施加电场并撤销所施加电场后，在电场与取向膜的共同作用下，如图14并结合图5所示，液晶层500的液晶分子形成为第一子单元区域1、第二子单元区域2和第三子单元区域3。其中，第一子单元区域1和第二子单元区域2内液晶分子分别为第一初始取向和第二初始取向，第三子单元区域3具有第三初始取向，该第三初始取向为从所述第一初始取向沿第一旋转方向朝所述第二初始取向转动时的其中一取向。其中，第一初始取向与第一摩擦方向是相 同的，第二初始取向与第二摩擦方向是相同的。具体的，在图14中，第一摩擦方向和第二摩擦方向是相互垂直的关系，即第一初始取向和第二初始取向也是相互垂直的。
结合图14与图15，所述第一子单元区域1对应所述第一电极区域750的第一部分751；所述第三子单元区域3对应所述第一电极区域750的第二部分752和所述第三电极区域770的组合区域；所述第二子单元区域2对应所述第二电极区域760。所述第一电极区域750的第一部分751与所述第一电极区域750的第二部分752组合形成为所述第一电极区域750，所述第一电极区域750的第二部分752与所述第三电极区域770相邻设置。
当在加电情况下，形成为如图16所示结构，第一子单元区域1内的液晶分子具有第一方向，第二子单元区域2内的液晶分子具有第二方向，第三子单元区域3内的液晶分子具有第三方向，且第三方向为从所述第一方向沿所述第一旋转方向朝所述第二方向转动时的其中一方向。
本公开文本第三实施例和第四实施例中，利用第一取向膜400和第二取向膜600与电极之间的配合结构，在初始状态通过对电极施加电压使液晶分子发生偏转，当去除电压后，第一子单元区域1、第二子单元区域2和第三子单元区域3所对应液晶层的液晶分子分别依据取向膜的取向而被定位，因此使得第三子单元区域3所对应液晶层的液晶分子形成规则排列的第三初始取向。同样，在施加电场后，利用设置于第一电极711和第二电极712之间的第三电极713，在电场的作用下，使第三子单元区域3所对应液晶层的液晶分子呈均匀排列，因此，在初始取向与施加电场的情况下，都能够达到避免该部分区域内“向错点”产生的问题。
当然，可选地，在第三实施例和第四实施例中，为避免第一子单元区域1和第二子单元区域2之间的第三子单元区域3在未加电时产生“向错点”，第一摩擦方向与第二摩擦方向之间的差值小于90度。且可选地，第一摩擦方向为第一标准取向朝第一方向偏转第一角度的方向，第二摩擦方向为第二标准方向朝第一方向的相反方向偏转第二角度的方向，其中第一标准取向与第二标准取向之间的差值为90度。最佳地，所述第一角度小于等于1度，所述第一标准取向相对于一水平延伸方向呈90度，所述第二标准取向相对于所述 水平延伸方向呈0度。
因此，采用本公开文本第三实施例和第四实施例的显示面板，通过进一步改进电极的排列形式，更进一步保证避免预定区域范围内“向错点”的产生，以保证显示面板的显示亮度均匀性。
在上述几种实施例的实施基础上，还可以进一步采用对液晶层内的液晶分子加热之后通过施加电场的控制，使得在加电后液晶分子依序排列，改善加电以后的预定区域范围的向错点问题，例如当液晶分子灌进入液晶盒后，加热液晶盒到各向同性液相(I相)，然后，加电场的状况下，慢冷却到液晶的向列相(N相)，通常加热之后的电场控制，使两区域之间交界区域的液晶分子依据特定方向排列，避免预定区域范围内产生“向错点”。
进一步地，本公开文本还提供如图17所示结构的第五实施例的显示面板，用于表示一个像素单元的对应区域内液晶分子的结构形式。通过在第三子单元区域3的对应区域设置黑色矩阵，覆盖所述第三子单元区域3，进一步达到解决第三子单元区域3上的漏光问题。
本公开文本以上的实施例，整个显示装置中，与像素单元第三子单元区域对应液晶分子可以具有统一的初始取向，形成为图18所示的状态。图18表示显示装置液晶分子的第一种初始状态示意图，表示整个显示面板对应区域内液晶分子的第一种状态图；其中区域X形成为一个像素单元的对应区域，第一子单元区域1、第二子单元区域2和第三子单元区域3的组合与一个像素单元对应，整个显示装置的第三子单元区域3具有统一的第三初始取向，使得整个显示装置内不会产生“向错点”，也即上述的第一至第四实施例中，通过取向膜的摩擦方向的改进或者取向膜的摩擦方向与电极的排列方式之间组合的改进，能够达到避免整个显示装置内不会产生向错点。
图19表示整个显示装置的显示面板上液晶分子的第二种初始状态示意图，整个显示装置中，与像素单元第三子单元区域对应液晶分子可以具有不同的初始取向，具有一取向方向的液晶分子与具有另一取向方向的液晶分子交替排列。在图19所示状态中，具有45度取向方向的液晶分子与具有-45度取向方向的液晶分子交替排列，但第三子单元区域内液晶分子的排列方式并不限于此，只要呈规则排列即可。
结合图19所示，第一子单元区域1、第二子单元区域2和第三子单元区域3的组合与一个像素单元对应，其中区域Y形成为一个像素单元的对应区域，与区域Y相邻的像素单元区域内的第三子单元区域3所对应液晶分子的初始取向不同，产生“向错点”。通过该种结构，利用上述的第一至第四实施例中的其中一种，通过取向膜的摩擦方向的改进或者取向膜的摩擦方向与电极的排列方式之间组合的改进，能够达到避免整个区域Y内不会产生向错点，虽然相邻区域Y之间会产生“向错点”，但该向错点的位置是可控的，这样对位置可控的向错点可以进行有针对性的校正，从而减小向错点对显示的影响。
图20为图19所示结构的另一种形式，根据图20所示结构，在一个区域Y内，第三子单元区域3对应的液晶分子取向，与区域Y在列方向上相邻的另一个区域Y’的之间交界处的液晶分子取向不同。
图21为液晶分子在未加电时的另一种状态示意图，在该种状态下，在一个区域Y内，第一子单元1、第二子单元区域2和第三子单元区域3所对应的液晶分子分别发生偏转；其中一个区域Y内，第三子单元区域3的液晶分子对应呈水平，相邻另一个区域Y内，第三子单元区域3的液晶分子对应呈竖直，两者相互垂直。
因此，根据本公开文本所述显示面板，可以使整个显示装置内不会出现“向错点”，也可以使预定范围内不会出现“向错点”，该预定范围可以为一个或多个像素单元，也可以为整个显示装置，从而使得“向错点”的产生成为可控，避免对显示亮度的均匀性产生影响。本公开文本具体实施例另一方面还提供一种显示装置，包括如上的显示面板。本领域技术人员应该能够了解具有上述显示面板的显示装置的具体结构，在此不再赘述。
另外需要说明的是，本公开文本以上的实施例中，均以一个像素单元作为基本单元，对一个像素单元区域内不产生“向错点”时的结构进行了描述。可以理解的是，采用本公开文本的技术思想，不产生“向错点”的基本单元除可以为一个像素单元之外，也可以为大于一个像素单元或者为小于一个像素单元的形式，也即当一个基本单元为小于一个像素单元的区域时，采用本公开文本中的上述各实施例，使小于一个像素单元的对应区域内不会产生“向 错点”，而通过上述“向错点”可控方式的原理说明，此时一个像素单元的对应区域内可以包括多个基本单元，而多个基本单元之间也可以依据设计形成具有预定规律的“向错点”。
具有本公开文本上述结构的显示装置，可以为手机、电视以及显示器等，但并不限于该几种。
以上所述仅是本公开文本的示例性实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本公开文本原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视本公开文本的保护范围。
