Description

一种液晶显示面板 技术领域
本申请涉及显示技术领域，尤其涉及一种液晶显示面板。
 背景技术
通常，LCD的液晶分子在像素电场作用下偏转，使得背光光源通过RGB光阻后形成不同颜色的光。通过IC对GOA和数据线上信号的控制，从而形成各种图像的画面。由于黑色矩阵（BM）的遮挡，各光阻下对应的光源无法穿透至邻近光阻，故而不会形成色偏现象。但是在大视角状态下，此时BM的遮挡效果有限。由于像素电场的扰动，BM下的液晶会偏转一定角度，RGB光阻下的背光光源可透过液晶而从相邻光阻处射出，从而形成大视角色偏现象。
因此，现有技术存在缺陷，急需改进。

以下各实施例的说明是参考附加的图示，用以例示本申请可用以实施的特定实施例。本申请所提到的方向用语，例如[上]、[下]、[前]、[后]、[左]、[右]、[内]、[外]、[侧面]等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本申请，而非用以限制本申请。在图中，结构相似的单元是用以相同标号表示。
本申请针对现有的液晶显示面板，由于像素电场的扰动，黑色矩阵下方的液晶会偏转一定角度，从而在大视角下形成色偏的技术问题，本实施例能够解决该缺陷。
如图1所示，为本申请实施例一提供的液晶显示面板局部结构示意图。所述液晶显示面板包括排布于基板上相互交叉绝缘设置的数据线101和栅极线102，所述数据线101和所述栅极线102围成像素区域。在所述数据线101和所述栅极线102上形成薄膜晶体管103，其中所述薄膜晶体管103的源极103a与所述数据线101电连接。在所述薄膜晶体管103上绝缘的设置有公共电极层104，在所述公共电极层104上绝缘的设置有像素电极107和屏蔽电极108。其中，所述像素电极107设置于所述数据线101和所述栅极线102围成的所述像素区域，所述屏蔽电极108对应所述数据线的位置设置。
在一种实施例中，所述像素电极107和所述屏蔽电极108是同种材料通过同一道光罩同时形成的，所述像素电极107和所述屏蔽电极108相互绝缘设置。所述像素电极107通过像素电极过孔105与所述薄膜晶体管103的漏极103b电连接，所述屏蔽电极108通过屏蔽电极过孔106与所述公共电极层104电连接。
所述液晶显示面板还包括彩膜基板（未标示），以及设置于所述阵列基板与所述彩膜基板之间的液晶层（未标示），所述彩膜基板包括黑色矩阵109，所述黑色矩阵109对应所述数据线101和所述栅极线102以及所述薄膜晶体管103设置，所述黑色矩阵109起遮蔽作用。图中仅示意出位于所述数据线101方向上的所述黑色矩阵109，且所述黑色矩阵109的宽度大于等于所述数据线101的宽度。
所述屏蔽电极108位于所述数据线101正上方，呈现长条状，且所述屏蔽电极108的延伸方向平行于所述数据线101的延伸方向。在所述屏蔽电极108下方的绝缘层上设置有所述屏蔽电极过孔106，所述屏蔽电极108的一端通过所述屏蔽电极过孔106与所述公共电极层104电连接。
所述屏蔽电极108的长度大于等于所述像素电极107有效区域110的垂直长度H。所述屏蔽电极108的宽度小于等于对应所述黑色矩阵109的宽度。其中，所述屏蔽电极108的宽度最小值为工厂制程允许的最小值。
所述像素电极107可产生像素电场，可以使该像素电场范围内的液晶分子发生偏转，从而实现显示的效果。但是，该像素电场常常会对位于所述数据线101下方的液晶分子产生干扰，虽有所述黑色矩阵109的遮挡，但在大视角下任然存在漏光问题，若加宽所述黑色矩阵109的宽度，势必对像素的开口率造成影响。
本申请在所述数据线101正上方设置所述屏蔽电极108，由于所述屏蔽电极108与所述公共电极层104相连，所述屏蔽电极108可以形成屏蔽电场，所述屏蔽电极108与所述公共电极层104皆为公共电位，因此在所述屏蔽电场范围内的液晶分子无法发生偏转，即对应所述数据线101位置的液晶分子不发生偏转，从而能有效防止大视角状态下的漏光。
为实现上述目的，所述屏蔽电极108的长度需要完全覆盖所述像素电极107产生的电场所能干扰到的显示区域，故而所述屏蔽电极108的长度不能小于所述像素电极107有效区域110的垂直长度。对于宽度而言，为保证其有效性，所述屏蔽电极108的宽度可位于制程允许最小值和所述数据线101方向上的所述黑色矩阵109的宽度值之间。
如图2所示，为本申请实施例一提供的液晶显示面板沿A-A’的剖面图。所述液晶显示面板包括阵列基板1和彩膜基板2以及中间的液晶层（未标示）。所述阵列基板1包括在基板10上层叠设置的第一绝缘层11、第二绝缘层12、第三绝缘层13、数据线101、平坦层14、公共电极层104、第四绝缘层15，以及位于所述第四绝缘层15上的像素电极107和屏蔽电极108。所述屏蔽电极108对应所述数据线101设置于所述数据线101的正上方。所述屏蔽电极108通过过孔与所述公共电极层104电连接。所述彩膜基板2包括对应所述数据线101的黑色矩阵109，其中，所述屏蔽电极108的宽度小于等于所述黑色矩阵109的宽度。
如图中箭头所示，所述像素电极107产生使液晶分子偏转的像素电场，所述屏蔽电极108在所述数据线101的相应位置产生屏蔽电场，使得对应所述数据线101位置的液晶分子不发生偏转，从而避免在大视角下漏光的现象。
如图3所示，为本申请实施例二提供的液晶显示面板局部结构示意图。所述液晶显示面板包括：位于阵列基板上相互交叉绝缘设置的数据线301和扫描线302、薄膜晶体管303、公共电极层304、像素电极307、屏蔽电极308，以及位于彩膜基板上并对应所述数据线301的黑色矩阵309，还有位于所述阵列基板与所述彩膜基板之间的液晶层。其中，所述像素电极307通过像素电极过孔305与所述薄膜晶体管303连接，所述屏蔽电极308通过屏蔽电极过孔306与所述公共电极层304连接。
相较于实施例一而言，实施例二的区别特征在于：一所述屏蔽电极308包括呈多段设置的子屏蔽电极308a，各所述子屏蔽电极308a的延伸方向与所述像素电极307的延伸方向平行。相邻两所述子屏蔽电极308a通过衔接部位308b首尾相接。
在一种实施例中，各所述子屏蔽电极308a的宽度以及长度均相等。且相邻两所述子屏蔽电极308a之间的所述衔接部位308b的形状大小均相等。
所述屏蔽电极308两端的直线长度大于等于所述像素电极307有效区域310的垂直长度H’。所述屏蔽电极308在水平方向的宽度小于等于对应所述黑色矩阵309的宽度。其中，所述屏蔽电极308的宽度最小值为工厂制程允许的最小值。其中，所述屏蔽电极308的宽度为所述子屏蔽电极308a和所述衔接部位308b共同在水平方向上的宽度。
本实施例在所述数据线301正上方设置所述屏蔽电极308，由于所述屏蔽电极308与所述公共电极层304相连，所述屏蔽电极308可以形成屏蔽电场，所述屏蔽电极308与所述公共电极层304皆为公共电位，因此在所述屏蔽电场范围内的液晶分子无法发生偏转，即对应所述数据线301位置的液晶分子不发生偏转，从而能有效防止大视角状态下的漏光。
为实现上述目的，所述屏蔽电极308的长度需要完全覆盖所述像素电极307产生的像素电场所能干扰到的显示区域，故而所述屏蔽电极308的长度不能小于所述像素电极307有效区域310的垂直长度。对于宽度而言，为保证其有效性，所述屏蔽电极308的宽度可位于制程允许最小值和所述数据线301方向上的所述黑色矩阵309的宽度值之间。
本申请提供的液晶显示面板，通过在数据线上方增加与像素电极同种材料制作的屏蔽电极，且屏蔽电极通过绝缘层上的过孔与公共电极层相连接，故而在数据线附近形成屏蔽电场，防止该处液晶分子受到像素电极电场的影响。能有效防止大视角状态下的色偏现象，提升面板显示品质。与此同时，由于采用电场进行屏蔽作用，故而能减小彩膜基板上沿数据线方向设置的黑色矩阵宽度，从而达到提升面板开口率的目的，能有效提升显示面板的穿透率水平。
综上所述，虽然本申请已以优选实施例揭露如上，但上述优选实施例并非用以限制本申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为准。
