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
Bezel Less是指液晶显示器无前框或少前框。Bezel Less产品极大提升了液晶显示器的美观度，给客户带来更友好的体验。目前，液晶显示器一般会包括相对设置的TFT（薄膜晶硅管）基板和CF（彩膜）基板以及设置于CF基板的外侧的第一偏光片和设置于TFT基板的外侧上的第二偏光片。
现有液晶显示器中会采用CF基板内缩设计，即对CF基板的边缘部位进行切割，CF基板内缩会使的第一偏光片的边缘部位与TFT基板的边缘部位之间形成空隙。
为了防止边缘漏光，需要在液晶显示器的侧边涂胶，而涂胶时胶料难以有效均匀填充满第一偏光片与TFT基板之间的空隙，容易导致侧边出现严重的外观边缘气泡，影响面板品质。

本申请提供一种液晶显示面板，为使本申请的目的、技术方案及效果更加清楚、明确，以下参照附图并举实施例对本申请进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
本申请针对现有的液晶显示器中，在液晶显示器的侧边涂胶时胶料难以有效均匀填充满第一偏光片与TFT基板之间的空隙，容易导致侧边出现严重的外观边缘气泡，影响面板品质的技术问题。本申请可以解决上述问题。
一种液晶显示面板，如图1所示，包括薄膜晶体管基板20、彩膜基板10、设置于所述彩膜基板10的外侧上的上偏光片60、设置于所述薄膜晶体管基板20的外侧上的下偏光片70，以及，设置于所述彩膜基板10和所述薄膜晶体管基板20之间的框胶40和液晶层30。
其中，所述彩膜基板10在所述上偏光片60上的正投影包纳所述薄膜晶体管基板20在所述上偏光片60上的正投影；所述彩膜基板10的侧面上设置有与所述彩膜基板10、所述薄膜晶体管基板20以及所述上偏光片60固定连接的遮光胶层50，所述遮光胶层50绕所述彩膜基板10的周侧设置。
优化液晶显示面板的边缘部位的设计，将上偏光片60贴附在彩膜基板10上后，在彩膜基板10的侧边涂布遮光胶层50时，由于上偏光片60的边缘部位与薄膜晶体管基板20的边缘部位之间不存在大范围的空隙，可以有效避免遮光胶层50出现严重的外观边缘气泡，提升液晶显示面板的边缘品质。
在第一种实施方式中，所述彩膜基板10在所述上偏光片60上的正投影与所述薄膜晶体管基板20在所述上偏光片60上的正投影重合。
将彩膜基板10与薄膜晶体管基板20对位贴合后，对彩膜基板10的边缘部位进行切割处理，从而使得彩膜基板10的侧面与薄膜晶体管基板20的侧面齐平。
在第二种实施方式中，如图2所示，所述彩膜基板10包括第一主体部11以及向远离所述第一主体部11方向延伸的第一边缘部12，所述第一主体部11在所述上偏光片60上的正投影与所述薄膜晶体管基板20在所述上偏光片60上的正投影重合。
第一边缘部12与第一主体部11一体成型以形成彩膜基板10，并且第一边缘部12向外延伸以凸露出薄膜晶体管基板20的边缘，从而使得上偏光片60的边缘部位与薄膜晶体管基板20的边缘部位之间不存在大范围的空隙。
进一步的，所述第一边缘部12绕所述第一主体部11的周侧设置。
进一步的，所述第一边缘部12向远离所述第一主体部11方向延伸的长度为30～130微米。
在一实施方式中，所述第一边缘部12向远离所述第一主体部11方向延伸的长度为50、80或100微米。
具体的，所述上偏光片60在所述薄膜晶体管基板20上的正投影包纳所述彩膜基板10在所述薄膜晶体管基板20上的正投影，从而使得彩膜基板10的整面都被上偏光片60覆盖，提升液晶显示面板的边缘美观度。
在一实施方式中，所述上偏光片60包括第二主体部61以及向远离所述第二主体部61方向延伸的第二边缘部62，所述第二主体部61在所述薄膜晶体管基板20上的正投影与所述彩膜基板10在所述薄膜晶体管基板20上的正投影重合，所述遮光胶层50与所述第二边缘部62的内侧面接触连接。
第二边缘部62与第二主体部61一体成型以形成上偏光片60，并且第二边缘部62向外延伸以凸露出彩膜基板10的边缘。
在另一实施方式中，如图3所示，所述上偏光片60在所述薄膜晶体管基板20上的正投影与所述彩膜基板10在所述薄膜晶体管基板20上的正投影重合，所述遮光胶层50与所述上偏光片60的侧面接触连接。
需要说明的是，图3中仅示意了上偏光片60的边侧面、彩膜基板10的边侧面以及薄膜晶体管基板20的边侧面均齐平的情况，实际实施中，在上偏光片60的边侧面与彩膜基板10的边侧面齐平的前提下，彩膜基板10的边缘部位也可以设置成凸露出薄膜晶体管基板20的边缘。
具体的，所述薄膜晶体管基板20在所述彩膜基板10上的正投影包纳所述下偏光片70在所述彩膜基板10上的正投影，并且所述下偏光片70的边缘延伸至与所述框胶40相对应的位置。
具体的，所述遮光胶层50的一部分位于所述彩膜基板10与所述薄膜晶体管基板20之间，加强遮光胶层50与彩膜基板10和薄膜晶体管基板20的连接强度，同时起到更好的遮光效果，防止边缘漏光。
本申请的有益效果为：通过优化彩膜基板10的边缘部位的结构，使得彩膜基板10的边侧面与薄膜晶体管基板20的边侧面齐平，或者将彩膜基板10的边缘部位设置成凸露出薄膜晶体管基板20的边缘，将上偏光片60贴附在彩膜基板10上后，在彩膜基板10的侧边涂布遮光胶层50时，由于上偏光片60的边缘部位与薄膜晶体管基板20的边缘部位之间不存在大范围的空隙，可以有效避免遮光胶层50出现严重的外观边缘气泡，提升液晶显示面板的边缘品质。
可以理解的是，对本领域普通技术人员来说，可以根据本申请的技术方案及其申请构思加以等同替换或改变，而所有这些改变或替换都应属于本申请所附的权利要求的保护范围。
