具体实施方式
LCD中的显示面板一般由制作完成的阵列基板和液晶显示面板对盒组装而成，阵列基板和液晶显示面板之间设置有封框胶，以保证阵列基板和液晶 显示面板贴合的密封性。显示面板可分为显示区域和位于显示区域四周的外围区域，封框胶位于显示面板的外围区域。随着窄边框液晶显示技术的发展，显示面板的外围区域越来越窄，使得位于显示面板外围区域的封框胶的宽度也越来越窄，但是封框胶的宽度过窄会降低阵列基板与液晶显示面板的附着力强度。
为了使本公开的目的，技术方案和优点更加清楚，下面结合附图，对本公开实施例提供的液晶显示面板、其制作方法及显示装置的具体实施方式进行详细地说明。
附图中各层薄膜厚度和形状不反映液晶显示面板的真实比例，目的只是示意说明本公开内容。
相关技术中的液晶显示面板，如图1所示，包括：相对设置的阵列基板1和彩膜基板2，以及位于阵列基板1和彩膜基板2之间的封框胶3；阵列基板1包括：第一衬底基板10、位于第一衬底基板10朝向彩膜基板2一侧的栅极绝缘层20和位于栅极绝缘层20朝向彩膜基板2一侧的钝化层30，彩膜基板2包括第二衬底基板40、位于第二衬底基板40朝向阵列基板1一侧的黑矩阵层50和位于黑矩阵层50朝向阵列基板1一侧的平坦化层60。随着窄边框液晶显示技术的发展，显示面板的外围区域越来越窄，使得位于显示面板外围区域的封框胶3的宽度也越来越窄，但是封框胶3的宽度过窄会降低阵列基板1与液晶显示面板的附着力强度。
有鉴于此，本公开实施例提供了一种液晶显示面板，如图2至图4所示，包括：相对设置的阵列基板1和彩膜基板2，以及位于阵列基板1和彩膜基板2之间的封框胶3；其中，
在阵列基板1和彩膜基板2中至少一个基板与封框胶3的接触面具有凹凸结构4。具体，如图2所示，在阵列基板1与封框胶3的接触面具有凹凸结构4；或者，如图3所示，在彩膜基板2与封框胶3的接触面具有凹凸结构4；或者，如图4所示，在阵列基板1与封框胶3的接触面具有凹凸结构4，且在 彩膜基板2与封框胶3的接触面也具有凹凸结构4。
本公开实施例提供的液晶显示面板，通过在阵列基板和彩膜基板中至少一个基板与封框胶的接触面具有凹凸结构，可以增大封框胶与基板之间的接触面积，增强封框胶和基板之间的粘附性，并且凹凸结构可以有效的防止外界水汽进入液晶盒内，从而可以提高液晶显示面板的抗水汽能力。
可选地，在本公开实施例提供的液晶显示面板中，如图5至图7所示，阵列基板1包括第一衬底基板10和位于第一衬底基板10朝向彩膜基板2一侧的钝化层30；
凹凸结构包括第一凹凸结构41，第一凹凸结构41位于钝化层30与封框胶3的接触面。
可选地，在本公开实施例提供的液晶显示面板中，第一凹凸结构可以通过在钝化层与封框胶对应的区域形成凹槽的方式形成。如图5和图7所示，在钝化层30与封框胶3对应的区域，钝化层30的凹陷部的深度d1小于钝化层30的厚度，即钝化层30的凹陷部没有贯穿钝化层30，这样可以避免在制作后续膜层时对钝化层30与第一衬底基板10之间的其它膜层造成影响。
可选地，在本公开实施例提供的液晶显示面板中，如图6和图7所示，彩膜基板2包括第二衬底基板40和位于第二衬底基板40朝向阵列基板1一侧的平坦化层60；凹凸结构包括第二凹凸结构42，第二凹凸结构42位于平坦化层60与封框胶3的接触面。
可选地，在本公开实施例提供的液晶显示面板中，第二凹凸结构可以通过在平坦化层与封框胶对应的区域形成凹槽的方式形成。如图6和图7所示，在平坦化层60与封框胶3对应的区域，平坦化层60的凹陷部的深度d2小于平坦化层60的厚度，即平坦化层60的凹陷部没有贯穿平坦化层60，这样可以避免在制作后续膜层时对平坦化层60与第二衬底基板40之间的其它膜层造成影响。
本公开实施例提供的液晶显示面板，通过在钝化层和平坦化层中的至少一个膜层在与封框胶对应的区域中设置凹凸结构，可以增大封框胶和平坦化 层和/或钝化层之间的接触面积，增强封框胶和平坦化层和/或钝化层之间的粘附性，并且凹凸结构可以有效的防止外界水汽进入液晶盒内，从而可以提高液晶显示面板的抗水汽能力。
可选地，在本公开实施例提供的上述液晶显示面板中，如图5至图7所示，钝化层30的凹陷部的深度d1和平坦化层60的凹陷部的深度d2相等。这样可以统一制作工艺，简化制作流程。
可选地，在本公开实施例提供的上述液晶显示面板中，如图7所示，彩膜基板2还包括位于第二衬底基板40和平坦化层60之间的黑矩阵层50，黑矩阵层50与平坦化层60的接触面在与封框胶3对应的区域具有与第二凹凸结构42相对应的第三凹凸结构43；
且在与封框胶3对应的区域内平坦化层60的厚度均匀。
本公开是通过先在黑矩阵层50上与封框胶3对应的区域通过光刻工艺刻蚀多个凹槽，从而形成第三凹凸结构43，然后在黑矩阵层50上涂覆平坦化层60，即平坦化层60的材料会覆盖黑矩阵层50的表面，从而使平坦化层60具有第二凹凸结构42。由于平坦化层60本身是透明的，不利于进行曝光等工艺，因此本公开先在黑矩阵层50上制作第三凹凸结构43。
可选地，在本公开实施例提供的上述液晶显示面板中，如图6和图7所示，在黑矩阵层50与封框胶3对应的区域，黑矩阵层50的凹陷部的深度d3小于黑矩阵层50的厚度。这是由于黑矩阵层50具有遮光效果，如果黑矩阵层50的凹陷部贯穿黑矩阵层50，则贯穿的凹陷部会透光，在进行黑画面显示时会出现亮光，影响显示面板的显示效果。
可选地，在本公开实施例提供的上述液晶显示面板中，如图4和图7所示，凹凸结构包括第一凹凸结构41和第二凹凸结构42；
第一凹凸结构41位于阵列基板1与封框胶3的接触面，第二凹凸结构42位于彩膜基板2与封框胶3的接触面。
且第一凹凸结构41的凹陷部与第二凹凸结构42的凹陷部位置相对。
可选地，在本公开实施例提供的上述液晶显示面板中，第一凹凸结构的 凹陷部在彩膜基板上的正投影与第二凹凸结构的凹陷部重叠。
即第一凹凸结构41和第二凹凸结构42对称设置，有利于统一制作工艺，简化制作流程。
可选地，在本公开实施例提供的上述液晶显示面板中，如图7所示，在同时具有第一凹凸结构41和第二凹凸结构42时，钝化层30的凹陷部和平坦化层60的凹陷部相对设置。即第一凹凸结构41和第二凹凸结构42对称设置，有利于统一制作工艺，简化制作流程。
可选地，在本公开实施例提供的上述液晶显示面板中，如图7所示，钝化层30的凹陷部在第一衬底基板10上的正投影的面积和平坦化层60的凹陷部在第二衬底基板40上的正投影的面积相等。这样可以进一步统一制作工艺，简化制作流程。
具体实施时，本公开实施例提供的凹凸结构中凹陷部的数量和宽度可以根据产品的参数进行调整以选取最优条件，在此不做限定。
需要说明的是，在本公开实施例提供的上述液晶显示面板中，以阵列基板中与封框胶接触的膜层为钝化层为例进行说明的，对于在阵列基板中与封框胶接触的膜层为其它膜层的液晶显示面板同样适用，在此不作详述。同理，以彩膜基板中与封框胶接触的膜层为平坦化层为例进行说明的，对于在彩膜基板中与封框胶接触的膜层为其它膜层的液晶显示面板同样适用，在此不作详述。
另外，需要说明的是，在本公开实施例提供的上述液晶显示面板中，阵列基板中除了上述钝化层还设置有实现液晶显示的其它的必备膜层，彩膜基板中除了上述黑矩阵层和平坦化层还设置有实现液晶显示的其它的必备膜层，在此不作详述。
基于同一发明构思，本公开实施还提供了一种本公开实施例提供的上述任一种液晶显示面板的制作方法，如图8所示，包括：
S801、形成阵列基板和彩膜基板；其中，在形成阵列基板和彩膜基板时，至少在一个基板与将要形成的封框胶对应的区域形成凹凸结构；
S802、在阵列基板与彩膜基板之间形成封框胶。
本公开实施例提供的液晶显示面板的制作方法，通过在阵列基板和彩膜基板中的至少一个基板在与封框胶的接触面形成凹凸结构，可以增大封框胶和阵列基板和/或彩膜基板之间的接触面积，增强封框胶和阵列基板和/或彩膜基板之间的粘附性，并且凹凸结构可以有效的防止外界水汽进入液晶盒内，从而可以提高液晶显示面板的抗水汽能力。
在具体实施时，在本公开实施例提供的上述液晶显示面板的制作方法中，对阵列基板和彩膜基板形成顺序不作限定，可以先形成阵列基板再形成彩膜基板，也可以先形成彩膜基板再形成阵列基板。
可选地，在本公开实施例提供的上述液晶显示面板的制作方法中，在阵列基板与将要形成的封框胶对应的区域形成凹凸结构，具体包括：
在第一衬底基板上形成钝化层的图形，钝化层在与封框胶对应的区域具有第一凹凸结构。
可选地，在本公开实施例提供的上述液晶显示面板的制作方法中，在彩膜基板与将要形成的封框胶对应的区域形成凹凸结构，具体包括：
在第二衬底基板上形成黑矩阵层的图形，黑矩阵层在封框胶对应的区域具有第三凹凸结构；
在黑矩阵层上涂布平坦化层，平坦化层在与封框胶对应的区域具有与第三凹凸结构相对应的第二凹凸结构，且在与封框胶对应的区域内平坦化层的厚度均匀。
可选地，在本公开实施例提供的上述液晶显示面板的制作方法中，在黑矩阵层中在与封框胶对应的区域中通过一次构图工艺形成第三凹凸结构。这样在制备液晶显示面板时，通过一次构图工艺形成黑矩阵的图形的同时形成第三凹凸结构的图形，不用增加单独制备第三凹凸结构的工艺，可以简化制备工艺流程，节省生产成本，提供生产效率。
可选地，在本公开实施例提供的上述液晶显示面板中，衬底基板可以为玻璃基板，在此不作限定。
需要说明的是，在本公开实施例提供的上述制作方法中，构图工艺可只包括光刻工艺，或，可以包括光刻工艺以及刻蚀步骤，同时还可以包括打印、喷墨等其他用于形成预定图形的工艺；光刻工艺是指包括成膜、曝光、显影等工艺过程的利用光刻胶、掩模板、曝光机等形成图形的工艺。可选地，可根据本公开中所形成的结构选择相应的构图工艺。
下面以图7所示的液晶显示面板为例说明其制作方法。该液晶显示面板的制作可以包括以下步骤：
制作阵列基板1：
(1)通过一次构图工艺在第一衬底基板10上形成栅极绝缘层20，如图9a所示。
(2)通过一次构图工艺在形成有栅极绝缘层20的第一衬底基板10上形成钝化层30，如图9b所示；
(3)通过一次构图工艺在钝化层30与将要形成的封框胶对应的区域形成有第一凹凸结构41的图形，钝化层30的凹陷部的深度小于钝化层30的厚度，如图9c所示；这样可以避免在制作后续膜层时对钝化层30与第一衬底基板10之间的其它膜层造成影响。
通过上述步骤(1)-(3)形成本公开实施例提供的液晶显示面板的阵列基板1。
制作彩膜基板2：
(1’)通过一次构图工艺在第二衬底基板40上形成黑矩阵层50的图形，如图10a所示。
(2’)通过一次构图工艺在黑矩阵层50与将要形成的封框胶对应的区域形成有第三凹凸结构43的图形，黑矩阵层50的凹陷部的深度小于黑矩阵层50的厚度，如图10b所示；
这是由于黑矩阵层50具有遮光效果，如果黑矩阵层50的凹陷部贯穿黑矩阵层50，则贯穿的凹陷部会透光，在进行黑画面显示时会出现亮光，影响显示面板的显示效果。
(3’)在形成具有第三凹凸结构43的黑矩阵层50的第二衬底基板40上涂布平坦化层60，平坦化层60在与封框胶对应的区域具有与第三凹凸结构43相对应的第二凹凸结构42，且在与封框胶对应的区域内平坦化层60的厚度均匀；如图10c所示；
通过上述步骤(1’)-(3’)形成本公开实施例提供的液晶显示面板的彩膜基板2。
在上述形成的阵列基板1与彩膜基板2之间涂覆封框胶3，形成图7所示的液晶显示面板，该显示面板通过在钝化层和平坦化层中在与封框胶对应的区域中设置有凹凸结构，可以增大封框胶和平坦化层和/或钝化层之间的接触面积，增强封框胶和平坦化层和/或钝化层之间的粘附性，并且凹凸结构可以有效的防止外界水汽进入液晶盒内，从而可以提高液晶显示面板的抗水汽能力。
本公开实施例提供的液晶显示面板的制作方法是钝化层和平坦化层在与封框胶对应的区域中均设置有凹凸结构，具体实施时，也可以只在钝化层中在与封框胶对应的区域中设置有第一凹凸结构或只在平坦化层中在与封框胶对应的区域中设置有第二凹凸结构，具体根据实际需要进行选择。
可选地，本公开实施例提供的液晶显示面板还包括其它功能膜层，这些功能膜层与相关技术中技术一样，在此不做赘述。
基于同一发明构思，本公开实施例还提供了一种显示装置，包括本公开实施例提供的上述液晶显示面板。该显示装置可以为：手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。对于该显示装置的其它必不可少的组成部分均为本领域的普通技术人员应该理解具有的，在此不做赘述，也不应作为对本公开的限制。该显示装置的实施可以参见上述液晶显示面板的实施例，重复之处不再赘述。
本公开实施例提供的上述液晶显示面板、其制作方法及显示装置，通过在阵列基板和彩膜基板中至少一个基板与封框胶的接触面具有凹凸结构，可以增大封框胶与基板之间的接触面积，增强封框胶和基板之间的粘附性，并 且凹凸结构可以有效的防止外界水汽进入液晶盒内，从而可以提高液晶显示面板的抗水汽能力。
显然，本领域的技术人员可以对本公开进行各种改动和变型而不脱离本公开的精神和范围。这样，倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
