本申请提出一种显示面板100，其应用于显示装置（例如液晶显示器、液晶电视机、手机、平板电脑等），旨在降低框胶30遮蔽对位标记40的可能性，提升显示面板100的生产良率。
以下将就显示面板100的具体结构进行描述。
如图1和图2所示，在本申请显示面板100一实施例中，该显示面板100包括：
第一基板10；
第二基板20，所述第二基板20与所述第一基板10相对设置；
显示介质（未图示），所述显示介质设于所述第一基板10和所述第二基板20之间；
框胶30，所述框胶30设于所述第一基板10和所述第二基板20之间，并围设于所述显示介质的周围；
对位标记40，所述对位标记40设于所述第一基板10和所述第二基板20之间，且位于所述框胶30的外侧；以及
挡墙50，所述挡墙50设于所述第一基板10和所述第二基板20之间，所述挡墙50设置于所述对位标记40与所述框胶30之间。
具体地，显示面板100可以是液晶显示面板、有机电激发光显示面板、或者电泳显示面板。与之对应地，显示介质可以为液晶层、有机电激发光层、或者电泳液层。进一步地，框胶30则用于将显示介质密封和限定在第一基板10和第二基板20之间。下面以显示面板100是液晶显示面板、且第一基板10是薄膜晶体管阵列基板（Thin Film Transistor，简称TFT）、第二基板20是彩色滤光片（Color Filter，简称CF）为例进行介绍：
对位标记40既可以设置在第一基板10上，也可以设置在第二基板20上。对位标记40的形状可以是“十”字形、“米”字形等，对位标记40既可以是实体图案，也可以是镂空图案。例如：当对位标记40位于第一基板10上时，对位标记40可与薄膜晶体管阵列基板（TFT）中的金属层一起制作，此时，对位标记40可为“十”字形实体图案；当对位标记40位于第二基板20上时，对位标记40可与彩色滤光片（CF）中的黑矩阵一起制作，此时，对位标记40可为“十”字形镂空图案。
本实施例中，挡墙50凸设于第一基板10的面向第二基板20的表面，且朝向第二基板20延伸设置，并且，挡墙50的背离第一基板10的一端（上端）与第二基板20间隔设置，以避免与第二基板20抵持，防止对液晶盒盒厚造成不良影响。在框胶30未发生溢流的情况下，挡墙50横隔于对位标记40与框胶30之间，既可以呈折线形设置（例如“L”形），也可以呈弧形（例如圆弧形）设置。也即，挡墙50位于框胶30的外侧。而当框胶30发生溢流时，框胶30的宽度会明显地变宽，且向对位标记40流动，此时，横隔于对位标记40与框胶30之间的挡墙50便可起到阻挡框胶30继续流动的作用，从而有效降低框胶30遮蔽对位标记40的可能性。
因此，可以理解的，本申请的技术方案，通过于对位标记40与框胶30之间横隔设置挡墙50，在框胶30溢流至遮蔽对位标记40之前，其必须绕过挡墙50才有机会遮蔽对位标记40。也即，横隔于对位标记40与框胶30之间的挡墙50可起到阻挡框胶30流向对位标记40的作用，从而有效降低框胶30遮蔽对位标记40的可能性，增进第一基板10与第二基板20之间对位的精确度，提升显示面板100的生产良率。
此外，挡墙50可以为色阻挡墙50，即挡墙50的材质与色阻的材质相同。此时，挡墙50可与色阻一并制作，以简化工艺流程。当然，挡墙50也可以为隔垫物（PS）挡墙50，即挡墙50的材质与隔垫物（PS）的材质相同。此时，挡墙50可与隔垫物（PS）一并制作，以简化工艺流程。
如图1和图2所示，在本申请显示面板100一实施例中，所述挡墙50包括第一子挡墙51和第二子挡墙53，所述第一子挡墙51横隔于所述对位标记40与所述框胶30之间，所述第二子挡墙53横隔于所述第一子挡墙51与所述框胶30之间。如此，对位标记40与框胶30之间的、可起到阻挡框胶30流向对位标记40的障碍的数量得以增加，此时，若框胶30发生溢流，则必须绕过至少两道子挡墙才能够遮蔽对位标记40。这样，可使得框胶30遮蔽对位标记40的可能性得以进一步降低，使得第一基板10与第二基板20之间对位的精确度、显示面板100的生产良率得以进一步提升。
如图1和图2所示，在本申请显示面板100一实施例中，所述第一子挡墙51凸设于所述第一基板10，且朝向所述第二基板20延伸设置，所述第一子挡墙51的背离所述第一基板10的端部与所述第二基板20间隔设置；
所述第二子挡墙53凸设于所述第一基板10，且朝向所述第二基板20延伸设置，所述第二子挡墙53的背离所述第一基板10的端部与所述第二基板20间隔设置。
如此，不仅可有效实现对框胶30的双重阻挡，而且结构简单、生产方便，稳定性、可靠性高。
如图1和图2所示，在本申请显示面板100一实施例中，所述第二基板20的面向所述第一基板10的表面开设有沟槽60，所述沟槽60横隔于所述对位标记40与所述框胶30之间，且位于所述第一子挡墙51与所述第二子挡墙53之间。
可以理解的，沟槽60的设计，相当于在框胶30溢流的过程中，又新增了一道障碍，框胶30必须填满沟槽60后才能跨越这道障碍。如此，对位标记40与框胶30之间的、可起到阻碍框胶30流向对位标记40的障碍的数量得以增加，此时，若框胶30发生溢流，则必须首先绕过一道子挡墙50、然后填满两道子挡墙之间的沟槽60、最后再绕过一道子挡墙50后，才能够遮蔽对位标记40。这样，可使得框胶30遮蔽对位标记40的可能性得以进一步降低，使得第一基板10与第二基板20之间对位的精确度、显示面板100的生产良率得以进一步提升。
并且，为了进一步增加框胶30溢流过程中填满并跨越沟槽60的难度，从而进一步降低框胶30达到并遮蔽对位标记40的可能性，所述沟槽60的宽度为20μm~1000μm。
如图3所示，在本申请显示面板100一实施例中，所述第一子挡墙51凸设于所述第一基板10，且朝向所述第二基板20延伸设置，所述第一子挡墙51的背离所述第一基板10的端部与所述第二基板20间隔设置；
所述第二子挡墙53凸设于所述第二基板20，且朝向所述第一基板10延伸设置，所述第二子挡墙53的背离所述第二基板20的端部与所述第一基板10间隔设置。
如此，不仅可有效实现对框胶30的双重阻挡，而且结构简单、生产方便，稳定性、可靠性高。更为重要的是，这样的设计，两道子挡墙各自与对应基板之间的间隙的间距被拉长，进一步增加了框胶30直接跨越两道子挡墙的难度，降低了框胶30达到并遮蔽对位标记40的可能性。
如图1和图2所示，在本申请显示面板100一实施例中，所述第一子挡墙51与所述第二子挡墙53平行设置，所述第一子挡墙51与所述第二子挡墙53之间的间距不低于20μm。如此，两道子挡墙之间的距离足够大，框胶30绕过两道子挡墙的难度进一步被提升，遮蔽对位标记40的风险进一步被降低。
进一步地，第一子挡墙51于第一基板10的投影长度大于第二子挡墙53于第一基板10的投影长度，如此，框胶30绕过第二子挡墙53的两端后，需要行进更多的路程方能绕过第一子挡墙51的两端，这样，框胶30到达对位标记40的难度更大、可能性更低。
如图4所示，在本申请显示面板100一实施例中，所述第二子挡墙53沿所述框胶30外轮廓的环绕方向延伸设置。
具体地，第二子挡墙53与框胶30的外轮廓平行设置。这样，可使得第二子挡墙53的沿基板板面延伸设置的两端均远离第一子挡墙51而靠近框胶30，如此，框胶30绕过第二子挡墙53的端部后、再绕过第一子挡墙51的端部的行程便会增加，也即，框胶30绕过两道子挡墙的难度进一步被提升，遮蔽对位标记40的风险进一步被降低。
如图4所示，在本申请显示面板100一实施例中，所述对位标记40位于所述显示面板100的角落处，所述第一子挡墙51具有沿所述第一基板10板面延伸设置的第一端和第二端，所述第一端和所述第二端分别朝向所述角落的两侧边延伸设置，以将所述对位标记40围设于所述角落处。
这样，对位标记40被第一子挡墙51围在一个相对独立的角落里，框胶30难以到达，从而使得对位标记40被遮蔽的风险进一步降低。
如图1和图2所示，在本申请显示面板100一实施例中，所述第一子挡墙51呈折线形（两段或两段以上）或弧形（圆弧、椭圆弧、或其他弧形）设置，这样，结构简单、生产方便，稳定性、可靠性高。
如图1和图2所示，在本申请显示面板100一实施例中，所述第二子挡墙53呈折线形（两段或两段以上）或弧形（圆弧、椭圆弧、或其他弧形）设置，这样，结构简单、生产方便，稳定性、可靠性高。
此外，需要说明的是，如图2和图3所示，当第一基板10是薄膜晶体管阵列基板（TFT）、第二基板20是彩色滤光片（CF）、且对位标记40设置在第一基板10上时，第二基板20的面向对位标记40的表面还开设有透光槽，该透光槽的底壁贯穿第二基板20上的遮光层（BM层），即该透光槽以彩色滤光片（CF）的玻璃基板的表面为底壁，以使彩色滤光片（CF）侧同样可捕捉到对位标记40。此时，可以理解的，该透光槽相当于透光孔，该透光孔的两端开口分别贯穿遮光层（BM层）的两表面。
本申请还提出一种显示装置，该显示装置包括显示面板100，该显示面板100的具体结构参照上述实施例，由于本显示装置采用了上述所有实施例的全部技术方案，因此至少具有上述所有实施例的全部技术方案所带来的所有效果，在此不再一一赘述。其中，显示装置为显示器、电视机、手机、平板电脑、或其他显示装置。
以上所述仅为本申请的可选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
