Description

液晶面板以及液晶显示器
技术领域 本发明涉及液晶显示器技术领域， 尤其涉及一种液晶面板以及包含该液晶 面板的液晶显示器。 背景技术 液晶显示器， 或称 LCD ( Liquid Crystal Display ) , 为平面超薄的显示设 备， 它由一定数量的彩色或黑白像素组成， 放置于光源或者反射板前方。 液晶 显示器功耗很低， 并且具有高画质、 体积小、 重量轻的特点， 因此倍受大家青 睐， 成为显示器的主流。 液晶显示器已广泛使用于各种电子产品中， 例如， 具 显示屏幕的计算机设备、 行动电话、 或数字相框等， 而广视角技术为目前液晶 显示器的发展重点之一。 然而， 当侧看或斜视的视角过大时， 广视角液晶显示 器常会发生色偏 （color shift ) 现象。 液晶面板是液晶显示器的重要组成部分， 液晶面板中包含多个像素单元， 各个像素单元可包含： 像素电极、 设置于薄膜晶体管 （TFT ) 基板侧的共享电极 TFTcom, 及设置于彩色滤光 （CF ) 基板侧的共享电极 CFcom ； 其中， 该像素电 极与该共享电极 TFTcom 形成该像素单元的储存电容 Cst， 且该像素电极与该共 享电极 CFcom 形成该像素单元的液晶电容 Clc。 传统中解决上述提到的色偏问 题的方法， 是通过将液晶面板中的每个像素单元分为两个像素区域， 在其中的 一个像素区域中增加补偿电容， 使两个像素区域中的子像素具有不用的液晶电 容 Clc， 以使不同像素区域产生不同的透射率与施加电压的关系， 使液晶面板实 现低色偏 （low color shift ) 的效果。 图 1是现有的一种液晶面板的像素单元 结构的等效电路的图示。 如图 1所示， 液晶面板中， 多个像素单元 10位于相互 垂直的多条数据线 Data与多条扫描线 Gate之间 （图 1中只是示例性的示出了 其中一个像素单元） ， 每一像素单元 10分为两个像素区域 10a和 10b。 像素区 域 10a中包含有连接到数据线 Data和扫描线 Gate的薄膜晶体管 Tl， 在像素区 域 10a中像素电极与彩色滤光基板侧的共享电极形成液晶电容 Clc l， 与薄膜晶 体管基板侧的共享电极 TFTcom形成存储电容 Cst l ;像素区域 10b中包含有连接 到数据线 Data和扫描线 Gate的薄膜晶体管 T2， 在像素区域 10b中像素电极与 彩色滤光基板侧的共享电极形成液晶电容 Clc2， 与薄膜晶体管基板侧的共享电 极 TFTcom形成存储电容 Cst2， 像素区域 10b中还增加有补偿电容 Cdown, 补偿 电容 Cdown的一端连接到薄膜晶体管基板侧的共享电极 TFTcom,另一端通过一共 享薄膜晶体管 （sharing TFT ) T3连接到一共享扫描线 （sharing gate l ine ) GateO o 由于增加了补偿电容 Cdown, 液晶面板在工作时， 像素区域 10b与像素 区域 10a产生不同的透射率与施加电压的关系达到解决液晶面板色偏的问题。

附图说明 图 1是现有的一种液晶面板的像素单元结构的等效电路的图示。 图 2是本发明实施例提供的液晶显示器的结构示意图。 图 3是本发明实施例提供的液晶面板的结构示意图。 图 4是本发明实施例的第一像素区域中彩色滤光基板上的共同电极的布局 结构示意图。 图 5是本发明实施例的第二像素区域中彩色滤光基板上的共同电极的布局 结构示意图。 具体实施方式 为了更好地阐述本发明的技术特点和结构， 以下结合实施例及其附图进行 详细描述。 图 2为本实施例提供的液晶显示器的结构示意图。 如图 2所示， 该液晶显 示器包括相对设置的液晶面板 100以及背光模组 200，由所述背光模组 200提供 显示光源给所述液晶面板 100， 以使所述液晶面板 100显示影像。 其中， 如图 3所示， 液晶面板 100包括相对设置的薄膜晶体管基板 1和彩 色滤光基板 2以及位于所述薄膜晶体管基板 1和彩色滤光基板 2之间的液晶层 3。 所述薄膜晶体管基板 1上设置有多个像素电极 4a、 4b， 所述彩色滤光基板 2上 设置有一共同电极 5， 像素电极 4a、 4b与共同电极 5之间形成液晶电容， 施加 在像素电极 4a、 4b和共同电极 5的电压差使得液晶层 3中的液晶发生偏转， 使 得光线可以穿透液晶层 3， 像素电极 4a、 4b和共同电极 5之间不同电压差会使 得液晶层 3具有不同的光线透射率。 所述薄膜晶体管基板 1上还设置有一钝化 层 8， 所述像素电极 4a、 4b设置于所述钝化层 8上； 所述像素电极 4a、 4b与所 述液晶层 3之间还设置有一隔离层 9。 所述液晶面板 100包含有多个像素单元 6 (图 1中只是示例性的示出了其中一个像素单元） ， 其中， 每一像素单元 6包 括第一像素区域 6a和第二像素区域 6b，所述彩色滤光基板 2上还设置有第一绝 缘层 7a和第二绝缘层 7b。 具体地， 参阅图 4和图 5， 其中图 4是第一像素区域 6a中彩色滤光基板 2 上的共同电极 5的布局结构示意图； 图 5是第二像素区域 6b中彩色滤光基板 2 上的共同电极 5的布局结构示意图。所述彩色滤光基板 2上包含有 RGB子像素 结构 201以及黑色矩阵 202， 如图 4所示， 在第一像素区域 6a中， 所述第一绝 缘层 7a位于所述彩色滤光基板 2与所述共同电极 5之间， 如图 5所示， 在第二 像素区域 6b中， 所述第二绝缘层 7b设置于所述第二像素区域 6b且位于所述彩 色滤光基板 2与所述共同电极 5之上， 以使第二像素区域 6b中的像素电极 4a 与共同电极 5之间的距离大于第一像素区域 6a中的像素电极 4b与共同电极 5 之间的距离。 在上述的实施例中， 由于位于薄膜晶体管基板 1上的像素电极 4a、 4b基本 位于同一水平面上， 通过在第一像素区域 6a和第二像素区域 6b中的彩色滤光 基板 2上， 设置不同布局顺序的共同电极 5和绝缘层 7a、 7b, 使第二像素区域 6b中的像素电极 4a与共同电极 5之间的距离大于第一像素区域 6a中的像素电 极 4b与共同电极 5之间的距离， 使像素单元 6中的第一像素区域 6a和第二像 素区域 6b具有不用的液晶电容， 产生不同的透射率与施加电压的关系， 达到低 色偏的效果。 在本实施例中， 为了使制备工艺更为简单， 所述第一绝缘层 7a和第二绝缘 层 7b具有相同的厚度， 其厚度为 100nm。当然，在另外的一些优选地实施例中， 也可以设置第二绝缘层 7b的厚度大于第一绝缘层 7a的厚度， 第一绝缘层 7a和 第二绝缘层 7b的厚度范围优选是 50nm~1000nm， 并且第二绝缘层 7b的厚度与 第一绝缘层 7a的厚度的差异在 50nm~500nm的范围内。 其中所述第一绝缘层 7a和第二绝缘层 7b的材料可以选择为氮化硅或氧化 硅。 在本是实施例中， 所述共同电极 5 的材料为氧化铟锡 ( Indium t in oxide ， 通）。 以上实施例提供的液晶面板通过设置位于彩色滤光基板上的共同电极的布 局结构， 使像素单元中的第一像素区域和第二像素区域具有不用的液晶电容， 以使第一像素区域和第二像素区域产生不同的透射率与施加电压的关系， 达到 解决液晶面板色偏的问题； 另外， 该共同电极的布局结构易于实现， 制备工艺 简单， 与现有技术相比你， 该液晶面板具有更小的开口率， 提高了液晶面板的 显示质量。
需要说明的是， 在本文中， 诸如第一和第二等之类的关系术语仅仅用来将 一个实体或者操作与另一个实体或操作区分开来， 而不一定要求或者暗示这些 实体或操作之间存在任何这种实际的关系或者顺序。 而且， 术语 "包括"、 "包 含"或者其任何其他变体意在涵盖非排他性的包含， 从而使得包括一系列要素 的过程、 方法、 物品或者设备不仅包括那些要素， 而且还包括没有明确列出的 其他要素， 或者是还包括为这种过程、 方法、 物品或者设备所固有的要素。 对 于一结构被描述是在另一元素的"上面 /上"或"下面 / 下"， 是指直接地或间接地 在该元素之上或下的情况， 而包含设置于其间的其它元素在没有更多限制的情 况下， 由语句 "包括一个…… "限定的要素， 并不排除在包括所述要素的过程、 方法、 物品或者设备中还存在另外的相同要素。
