本发明涉及液晶显示技术领域，特别是涉及一种液晶显示面板，以及应用该液晶显示面板的显示装置。
 背景技术
UV2A（Ultraviolet Vertical Alignment）技术是一种采用紫外线对垂直配向液晶显示器中的液晶进行配向的技术，其基本原理是在玻璃基板上涂有对紫外线具有反应的高分子材料的配向膜，在紫外线的照射下，配向膜表面的高分子主链会沿着紫外线照射的方向倾斜，从而使得液晶分子可以沿着这个主链方向倾斜。目前这种技术主要应用在具有大视角的垂直配向模式液晶显示器上，提高了大视角液晶显示器的开口率、对比度、响应速度等特性。
但由于UV2A技术采用特殊的正交垂直光配相方式，使得液晶显示器在亮态时，在子像素上形成“卐”的万字暗纹，万字暗纹的出现降低了液晶显示器的透光率。为了解决这个问题，目前采用的方法主要有：将万字暗纹的边缘外推到黑色矩阵处，使用黑色矩阵将万字暗纹的边缘遮挡住，或者将上电极的边缘的特定位置设计成放射性狭缝，将ITO电极边缘电场对液晶分子的作用力外移，从而将由边缘场效应引起的横竖暗纹外移出ITO的开口区，但这些方法仅仅是减弱了万字暗纹的边缘上的横竖暗纹，而对万字暗纹中间的十字暗纹没有影响。
因此，有必要提供一种液晶显示面板及应用该液晶显示面板的显示装置，通过在上电极和/或下电极的相应位置上设置狭缝，当液晶显示面板处于亮态时，通过狭缝的电场作用使得液晶分子发生相应的偏转，进而使得子像素中原本为十字暗纹的位置可以有一定的光出射，从而减弱十字暗纹，增加液晶显示面板的透光率。

 本发明的最佳实施方式
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面对实施例中所需要使用的附图作简单的介绍。下面描述中的附图仅为本发明的部分实施例，对于本领域普通技术人员而言，在不付出创造性劳动的前提下，还可以根据这些附图获取其他的附图。
现有的液晶显示面板包括多个子像素单元，每个子像素单元包括上电极、上配向膜、液晶层、下配向膜和下电极，子像素单元包括四个透光区，且相邻的透光区具有不同的配向方向，相邻透光区具有不同配向方向的原理如下：
上配向膜与下配向膜采用UV2A技术进行垂直配向，上配向膜的配向方向为交替排列的竖直向下方向和竖直向上方向，下配向膜的配向方向为交替排列的水平向左方向和水平向右方向，每个子像素单元包括上配向膜的一对竖直向下和竖直向上的配向方向，以及下配向膜的一对水平向左和水平向右的配向方向，因此当液晶显示面板处于亮态时，子像素单元将分成四个透光区，分别为左上方透光区、右上方透光区、左下方透光区和右下方透光区。例如，在左上方透光区中，由于上配向膜的配向方向呈竖直向下方向，下配向膜的配向方向呈水平向左方向，因此，处于左上方透光区中的液晶分子的配向方向将向左下方倾斜，且倾斜的方向与该透光区中上配向膜的配向方向呈45°角。其他透光区中液晶分子的配向方向同理可知，在此不做具体描述。
但在相邻的透光区的交界处，由于液晶分子即没有按照左上方透光区中液晶分子的左下方向偏转，也没有按照右上方透光区中液晶分子的左上方向偏转，其排列方向是介于两者之间，这就导致交界处的透光率低于这两个透光区的透光率，即在两个透光区的交界处出现了暗纹。
请参见图1，图1为现有的液晶显示面板中万字暗纹的图形示意图，型为“卐”的万字暗纹由两部分组成，一部分是处于中间部分的十字暗纹，另一部分是边缘的横竖暗纹，本说明书中的实施例是针对十字暗纹设计的方案，即针对相邻透光区的交界处所对应的暗纹，可以理解的是，十字暗纹包括与相邻透光区的水平交界所对应的水平暗纹和与相邻透光区的竖直交界所对应的竖直暗纹。
为了进一步了解暗纹的形成，本发明给出了子像素单元所对应的液晶分子的偏转状态图，如图2a所示。根据液晶分子的偏转状态，液晶将明显地分成四个区域，分别处在左上方透光区、右上方透光区、左下方透光区和右下方透光区，且在每个透光区中液晶分子的偏转状态基本相同，相邻透光区中的液晶分子的偏转状态不同，而在相邻两个透光区的交界处的液晶分子的偏转状态与两个透光区内的液晶分子偏转状态均不同，其中图中黑框圈出了左上方透光区和右上方透光区交界处的液晶分子。
为了清晰地看到该处的液晶分子的偏转状态，我们将其放大，如图2b所示，图2b为黑框范围内液晶分子的偏转状态的放大图，从图中可以看出，在交界处的液晶分子没有按照左上方透光区中液晶分子的左下方向偏转，也没有按照右上方透光区中液晶分子的左上方向偏转，其排列方向是介于两者之间，这就导致交界处的透光率低于这两个透光区的透光率，即在两个透光区的交界处出现了暗纹。
为了减弱暗纹，本发明将提供一种液晶显示面板，其包括多个子像素单元，每个子像素单元包括上电极、液晶层和下电极，其中，子像素单元包括四个透光区，且相邻的透光区具有不同的配向方向，相邻透光区的交界包括水平交界或竖直交界，所述液晶显示面板还包括：在相邻透光区的交界所对应的上电极和/或下电极的相应位置上设置狭缝，狭缝的开口方向平行于狭缝所在透光区中液晶分子的配向方向。
请参见图3，图3为本发明的液晶显示面板的第一优选实施例中上电极的结构示意图，图中箭头表示透光区域对应的液晶分子的配向方向。
在液晶显示面板的上电极30上，设置有狭缝31，狭缝31的开口方向平行于狭缝31所在透光区中液晶分子的配向方向。
为了减弱十字暗纹中的水平暗纹，优选地，狭缝31分布在相邻透光区的水平交界所对应的上电极的相应位置的两侧，且处于同一竖直线上的狭缝31相通连接。在这里可以很容易理解的是，相邻透光区的水平交界是指左上方透光区与左下方透光区之间的交界，以及右上方透光区与右下方透光区之间的交界。由于液晶分子在45°偏转时，液晶的透光率最大，因此，优选地，狭缝31与水平交界所对应的上电极的相应位置呈45°角。当液晶显示面板处于亮态时，即在上电极30和下电极上施加电压时，狭缝31处的电场将诱导该处的液晶分子发生相应的偏转，增加交界处的透光率，从而达到减弱现有技术中出现的水平暗纹的目的。
在本优选实施例中，处于相邻透光区交界处的狭缝呈周期性排列，如图3中，左上方透光区与左下方透光区之间的狭缝具有一定的周期性排列，右上方透光区与右下方透光区之间的狭缝具有一定的周期性排列，当然在其他的实施例中，也可以不呈周期性排列，在此不做具体限定，同时，狭缝的数量、开口宽度等参数可以根据暗纹的大小、宽度等来设置，在此不做具体限定。
本优选实施例中的狭缝设置在相邻透光区的水平交界处所对应的上电极的相应位置的两侧，在其他的实施例中，也可以仅在一侧进行设置狭缝，在此不做具体限定。
本优选实施例中的狭缝设置在上电极上，可以理解的是，狭缝也可以设置在下电极的相应位置上，或者同时在上电极和下电极的相应位置上设置狭缝，只要可以达到减弱现有技术中出现的水平暗纹的目的即可。
请参见图4，图4为本发明的液晶显示面板的第二优选实施例中上电极的结构示意图，图中箭头表示透光区域对应的液晶分子的配向方向。
在本优选实施例中，在液晶显示面板的上电极40上，设置有狭缝41，狭缝41的开口方向平行于狭缝41所在透光区液晶分子的配向方向。
为了减弱十字暗纹中的竖直暗纹，优选地，狭缝41分布在相邻透光区的竖直交界所对应的上电极的相应位置的两侧，且处于同一水平线上的狭缝41相通连接。由于液晶分子在45°偏转时，液晶的透光率最大，因此，优选地，狭缝41与竖直交界所对应的上电极的相应位置呈45°角。当液晶显示面板处于亮态时，即在上电极40和下电极上施加电压时，狭缝41处的电场将诱导该处的液晶分子发生相应的偏转，增加交界处的透光率，从而达到减弱现有技术中出现的竖直暗纹的目的。
在本优选实施例中，处于相邻透光区交界处的狭缝呈周期性排列，如图4中，左上方透光区与右上方透光区之间的狭缝具有一定的周期性排列，左下方透光区与右下方透光区之间的狭缝具有一定的周期性排列，当然在其他的实施例中，也可以不呈周期性排列，在此不做具体限定，同时，狭缝的数量、开口宽度等参数可以根据暗纹的大小、宽度等来设置，在此不做具体限定。
本优选实施例中的狭缝设置在相邻透光区的竖直交界处所对应的上电极的相应位置的两侧，在其他的实施例中，也可以仅在一侧进行设置狭缝，在此不做具体限定。
本优选实施例中的狭缝设置在上电极上，可以理解的是，狭缝也可以设置在下电极的相应位置上，或者同时在上电极和下电极的相应位置上设置狭缝，只要可以达到减弱现有技术中出现的竖直暗纹的目的即可。
请参见图5，图5为本发明的液晶显示面板的第三优选实施例中上电极的结构示意图，图中箭头表示透光区域对应的液晶分子的配向方向。
在本优选实施例中，在液晶显示面板的上电极50上，设置有狭缝51，狭缝51的开口方向平行于狭缝51所在透光区液晶分子的配向方向。
为了减弱十字暗纹中水平暗纹和竖直暗纹，优选地，狭缝51分布在水平交界和竖直交界所对应的上电极的相应位置的两侧，且处于同一水平线或同一竖直线上的狭缝51相通连接。由于液晶分子在45°偏转时，液晶的透光率最大，因此，优选地，狭缝51分别与竖直交界和水平交界所对应的上电极的相应位置呈45°角。当液晶显示面板处于亮态时，即在上电极50和下电极上施加电压时，狭缝51处的电场将诱导该处的液晶分子发生相应的偏转，增加交界处的透光率，从而达到减弱现有技术中出现的水平暗纹和竖直暗纹的目的。
在本优选实施例中，处于相邻透光区交界处的狭缝呈周期性排列，当然在其他的实施例中，也可以不呈周期性排列，在此不做具体限定，同时，狭缝的数量、开口宽度等参数可以根据暗纹的大小、宽度等来设置，在此不做具体限定。

请参见图6，图6为本发明的液晶显示面板的第四优选实施例中上电极的结构示意图，图中箭头表示透光区域对应的液晶分子的配向方向。
在本优选实施例中，在液晶显示面板的上电极60上，设置有狭缝61，狭缝61的开口方向平行于狭缝61所在透光区液晶分子的配向方向。
水平交界与竖直交界相交处为交界中心，优选地，狭缝61设置在距交界中心预定范围内的水平交界和竖直交界所对应的上电极的相应位置上，且处于同一水平线或同一竖直线上的狭缝61相通连接。由于液晶分子在45°偏转时，液晶的透光率最大，因此，优选地，狭缝61分别与预定范围内的竖直交界和水平交界所对应的上电极的相应位置呈45°角。当液晶显示面板处于亮态时，即在上电极60和下电极上施加电压时，狭缝61处的电场将诱导该处的液晶分子发生相应的偏转，增加交界中心预定范围内交界处的透光率，从而减弱水平暗纹与竖直暗纹交叉处的暗纹。
在本优选实施例中，在交界中心预定范围内的水平交界和竖直交界所对应的上电极的相应位置上设置狭缝，主要减弱水平暗纹与竖直暗纹交叉处的暗纹，在此预定范围的具体值可以根据交叉处的暗纹的大小来定，在此不做具体限定。

本优选实施例中的狭缝设置在上电极上，可以理解的是，狭缝也可以设置在下电极的相应位置上，或者同时在上电极和下电极的相应位置上设置狭缝，只要可以达到减弱交叉处的暗纹的目的即可。
请参见图7，图7为本发明的液晶显示面板的第五优选实施例中上电极的结构示意图，图中箭头表示透光区域对应的液晶分子的配向方向。
在本优选实施例中，在液晶显示面板的上电极70上，设置有狭缝71，狭缝71的开口方向平行于狭缝71所在透光区液晶分子的配向方向。
水平交界与竖直交界相交处为交界中心，优选地，狭缝71设置在距交界中心预定范围内的水平交界和竖直交界所对应的上电极的相应位置上，且距交界中心所对应的上电极70的相应位置相同距离的相邻狭缝71相通连接，从而形成如图7所示的口子形状。由于液晶分子在45°偏转时，液晶的透光率最大，因此，优选地，狭缝71分别与预定范围内的竖直交界和水平交界所对应的上电极的相应位置呈45°角。当液晶显示面板处于亮态时，即在上电极70和下电极上施加电压时，狭缝71处的电场将诱导该处的液晶分子发生相应的偏转，增加交界中心预定范围内交界处的透光率，从而减弱水平暗纹与竖直暗纹交叉处的暗纹。

本发明还提供一种显示装置，其中，显示装置包括上述任何一种优选的液晶显示面板，本发明的显示装置由于采用了具有较高的透光率的液晶显示面板，因此本发明提供的显示装置相比于现有的显示装置，其具有更高的透光率，其具有较高的透光率的原理请参见前面对液晶显示面板的详述，在此不做赘述。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选的实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
