液晶显示面板 技术领域
本发明涉及显示技术领域，特别涉及一种液晶显示面板。
 背景技术
随着高科技的发展，视频产品，特别是数字化的视频或影像装置已经成为一般生活中所常见的产品。这些数字化的视频或影像装置中，显示器是一个重要组件，用来显示相关信息。使用者可由显示器读取信息，进而控制装置的运作。
液晶显示面板作为液晶显示器的主要元件，其主要包含彩膜基板、阵列基板、偏光板等。彩膜基板与阵列基板的相对内侧设置透明电极，且彩膜基板与阵列基板之间设有一层液晶分子层。液晶显示面板是通过电场对液晶分子取向的控制，改变光的偏振状态，并藉由偏光板实现光线的穿透与阻挡，从而实现显示的目的。
液晶显示屏（LCD）是用于数字型钟表和许多便携式计算机的一种显示器类型。LCD显示使用了两片极化材料，在它们之间是液体水晶溶液。电流通过该液体时会使水晶重新排列，以使光线无法透过它们。因此，每个水晶就像百叶窗，既能允许光线穿过又能挡住光线。
 技术问题
本发明主要解决的技术问题是提供了一种液晶显示面板，以解决现有技术中由于金属走线在实际制程中的非水平/垂直结构而引起的漏光问题。

以上仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
实施例1
本实施例为最简化的一个实施方案。具体如下文所述。
如图1所示，为了有效解决液晶显示面板的漏光问题，本实施例提供了一种液晶显示面板，该液晶显示面板包括相对设置的阵列基板1和彩膜基板2。
所述阵列基板1分布有若干金属走线11和薄膜晶体管（图未示）。如图8所示，所述金属走线11包括横向金属走线111和纵向金属走线112。其中，所述横向金属走线111与纵向金属走线112垂直连接，连接处为交汇处。
如图2所示，所述彩膜基板2包括玻璃基板21、滤光层26，滤光层26设置在玻璃基板21上。其中，滤光层26包括彩色滤光片23和分布于彩色滤光片周边的第一黑色矩阵222。一般的，第一黑色矩阵222为方框状，用以遮挡彩色滤光片23周边的光。彩色滤光片23包括矩阵式排列的彩色滤光单元232，彩色滤光单元232之间存在空隙233，所述空隙233设置有用于遮光的第二黑色矩阵223，每一所述彩色滤光单元232包括至少一拐角。
如图3所示，为最常见的所述彩色滤光单元232，其在玻璃基板21上投影形状为长方形，因此，每一所述彩色滤光单元232的拐角应当包括4个。如图4所示，图4为第一黑色矩阵222与金属走线11的对应关系图。在第一黑色矩阵222的对应处设置相应的金属走线11，其中的所述横向金属走线111包括第三金属走线1112，纵向金属走线112包括第四金属走线1122，使得每一彩色滤光单元232对应的薄膜晶体管能够连接至金属走线11，而对应第一黑色矩阵222处的金属走线11为相互垂直连接的所述第四金属走线1122与第三金属走线1112，所述第四金属走线1122与第三金属走线1112的连接处为交汇区。而彩色滤光片23为长方形区域，该区域有边角，正如背景技术所述，在实际过程中，由于金属走线11在形成过程中，其精度或控制精度达不到要求时，其并非是一条完美的直线，使横纵交错分布在对应空隙区域的金属走线成非直线状态。因此，两条垂直连接的金属走线11的相交处与彩色滤光片23之间具有微小的缝隙，在偏光作用下，光线会发生类似衍射的效果，使得光线穿过缝隙产生漏光，特别是在两条垂直连接的金属走线相互交汇处，即彩色滤光单元的边角处，漏光现象尤为严重。
本实施例重在改进彩色滤光片23周边拐角处的漏光问题。而这些金属走线11因为制程的需要，无法去除。其中这些金属走线中的横向金属走线111包括第三金属走线1112，纵向金属走线112包括第四金属走线1122。第二金属走线1112与第四金属走线1122相互垂直连接，连接处为金属走线的交汇处。这些交汇处与拐角一一对应。在这些拐角处设置一内凹于该拐角所对应的色组单元的缺口231。这些缺口231用黑色凸起221遮挡，由于第一黑色矩阵222的存在，而这些第三金属走线1112与第四金属走线1122在玻璃基板21上的投影均落入第一黑色矩阵222上。
为了进一步使得缺口满足制程精度要求，在实施例1和2中，该缺口在负性曝光时，形成方形缺口。这些缺口在MACK制程中，该黑色凸起221与第一黑色矩阵222一体设置。该透光缺口在玻璃基板上的正向投影完全落入黑色凸起221内，使得黑色凸起221完全遮挡该透光缺口，同时利用光学补偿效应，可以使最终生成的黑色凸起221的直径或边长小于等于10um，最大程度的保留彩色滤光片23的透光面积。
实施例2
在实施例1的方案基础上，为了使本实施例的解决漏光方案适应TFT基板的要求，在实际的制作过程中，彩色滤光单元232之间的空隙的对应处必然还存在至少一条金属走线11，用以连接像素电极，使得彩色滤光单元232所对应的薄膜二极管通电。然而，为了避免该区域的金属走线11相互交叉，产生类似“衍射”现象，在实施例1中，如图6所示，横向金属走线11中包括第一金属走线1111，纵向金属走线112包括第二金属走线1121，第一金属走线1111和第二金属走线1121相互交错排列。那么此时，其中至少一条第一金属走线1111与其对应的一第二金属走线1121必然发生垂直连接，而至少一条第二金属走线1121与其对应的第三金属走线1112必然发生垂直连接，同样的至少一条第一金属走线1111与其对应的第四金属走线1122必然发生垂直连接因此，凡是两条金属走线11的交汇处所对应的拐角均设置一内凹的缺口231，并在该缺口231处设置有用以遮盖该缺口的黑色凸起221，具体如图5所示。同样的，这些黑色凸起221可以与这些缺口在MACK制程中，该黑色凸起221与第二黑色矩阵223一体设置。
实施例3
为了避免该区域的金属走线11相互交叉，产生类似“衍射”现象，同时为了节省材料和减少透光率的损失，在实施例2的基础上，删除对应第二黑色矩阵223区域的横向金属走线111或纵向金属走线112，即在本实施例中这些金属走线只包括横向金属走线111或纵向金属走线112。那么这些横向金属走线111或纵向金属走线112必然相互并排排列，而无交汇区，因此，在彩色滤光单元232之间区域则不存在因金属走线交叉而产生的类似“衍射”现象，因此，也不需要在这些彩色滤光单元232的拐角处设置缺口231。只需在其他对应金属走线的交汇区设置缺口231即可。
如图8所示，即在本实施例中，该横向金属走线111中包括第一金属走线1111，第一金属走线1111并排排列。或者纵向金属走线112包括第二金属走线1121，第二金属走线1121并排排列。本实施例只以第一金属走线1111为例进行说明，即第一金属走线1111与第四金属走线1122必然发生垂直连接，因此，凡是两条金属走线11的交汇处所对应的拐角均设置一内凹的缺口，具体如图7所示。在该缺口处设置用以遮盖该缺口的黑色凸起221。同样的，这些黑色凸起221可以与这些缺口在MACK制程中，该黑色凸起221与第二黑色矩阵223一体设置。
本发明的液晶显示面板可为超高清或全高清液晶显示面板。
可以理解的是，以上实施方式仅仅是为了说明本发明的远离而采用的示例性实施方式，然而本发明并不局限于此，对于本领域的不同技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本发明的保护范围。
