具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例的附图，对本发明实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，本领域普通技术人员在无需创造性劳动的 前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例一
本实施例提供一种显示面板，图1为一种显示面板的剖面结构示意图，如图1所示，该显示基板包括相对设置的第一基板1和第二基板2，填充于第一基板1与第二基板2之间的液晶层6，设置在第一基板1和第二基板2的周边用于粘合第一基板1和第二基板2的封框胶4，设置于第一基板1上的第一对位标记5和设置于第二基板2上的第二对位标记3，其中，第二对位标记3设置在封框胶4的靠近液晶层6的一侧，即第二对位标记3设置在封框胶4和液晶层6之间。基于以上设计，通过第一对位标记5与第二对位标记3在俯视方向上依照预设形状相匹配，可以有效提高对盒的精度，并可对对盒的过程进行检测。除此之外，第二对位标记3还可以阻挡未固化的封框胶的扩散，起到提高封框胶涂覆精度的作用。
如图1所示，第一对位标记5与第二对位标记3至少部分重叠，第一对位标记5除了包括与第二对位标记3相匹配的第一部分外，还包括和封框胶对应的第二部分。
例如，第一对位标记上还可以设置有多条刻度线，该刻度线可用于进一步提高对位的精度。
例如，第二对位标记3和封框胶4也可以部分重叠。
第一对位标记5与第一基板1上的任一膜层同层设置，第一基板上设置的膜层包括钝化层、源漏电极层、有源层、像素电极层、公共电极层、栅极绝缘层和栅极层，例如，源漏电极层和栅极层的材料包括铜、钼和钛中的一种或任意组合；栅极绝缘层的材料包括氮化硅(SiNx)、氧化硅(SiOx)、氧化铝(Al2O3)、氮化铝(AlN)或其他适合的材料；钝化层的材料包括氮化硅(SiNx)、氧化硅(SiOx)或丙烯酸类树脂；有源层的材料包括氧化物半导体、多晶硅半导体等；像素电极层和公共电极层的材料包括透明导电材料，例如氧化铟锡(ITO)、氧化铟锌(IZO)、氧化铟镓锌(IGZO)、氧化镓锌(GZO)等。
第二对位标记3与第二基板2上的任一膜层同层设置，第二基板上设置的膜层包括隔垫柱、黑矩阵和色阻层，隔垫柱和色阻层的材料可以是有机材料，例如，树脂材料等；黑矩阵的材料包括金属材料和树脂材料。
图2为另一种显示面板的剖面结构示意图，与图1中所示结构的不同 之处在于第一对位标记5只包括与第二对位标记3相匹配的部分而不包括与封框胶4相对应的部分。
图3为第一基板的俯视结构示意图，在第一基板1上设置任一膜层的过程中，例如，在第一基板上设置钝化层、源漏电极层、有源层、像素电极层、公共电极层、栅极绝缘层或栅极层的过程中，通过一次构图工艺形成第一对位标记5的图案。
图4为第二基板的俯视结构示意图，在第二基板2上设置任一膜层的过程中，例如，在第二基板上设置隔垫柱、黑矩阵或色阻层的过程中，通过一次构图工艺形成第二对位标记3的图案。
例如，第一对位标记5的形状为直角、不完全封闭的矩形。进行封框胶涂覆以及对盒工艺时以第一对位标记5和第二对位标记3为参考系，可以有效地提高对盒精度和封框胶涂覆工艺的精度。
第一基板1上设置的第一对位标记5与第二基板2上设置的第二对位标记3在俯视方向上的形状互补，可以组成一个完整的矩形，因此，可以有效地提高对盒的精度。
第二对位标记3的厚度与第一基板1和第二基板2对盒后形成的液晶盒的厚度相同，第二对位标记3可以对封框胶进行完全的遮挡，可以阻止液晶与封框胶的接触，降低基板内部液晶扩散对周边封框胶的冲击，防止断胶和避免未固化的封框胶对液晶造成的污染。
例如，封框胶内含有支撑组分，支撑组分包括硅球、玻璃纤维或两者的混合。第二对位标记3的厚度与第一基板1和第二基板2对盒后形成的液晶盒的厚度相同，第二对位标记3可以起到支撑作用，可以减少封框胶内支撑组分的质量百分含量，封框胶中支撑组分的质量百分含量大于等于0且小于等于1％。
需要说明的是，第一对位标记的图案可以设置在第一基板或第二基板上，并与另一基板上设置的第二对位标记相匹配。
实施例二

第一对位标记5与第一基板1上的任一膜层同层设置，设置在第一基板1上的膜层包括钝化层、源漏电极层、有源层、像素电极层、公共电极层、栅极绝缘层或栅极层。例如，源漏电极层和栅极层的材料包括铜、钼和钛中的一种或任意组合；栅极绝缘层的材料包括氮化硅(SiNx)、氧化硅(SiOx)、氧化铝(Al2O3)、氮化铝(AlN)或其他适合的材料；钝化层的材料包括氮化硅(SiNx)、氧化硅(SiOx)或丙烯酸类树脂；有源层的材料包括氧化物半导体、多晶硅半导体等；像素电极层和公共电极层的材料包括透明导电材料，例如氧化铟锡(ITO)、氧化铟锌(IZO)、氧化铟镓锌(IGZO)、氧化镓锌(GZO)等。

第一基板1上设置的第一对位标记5与第二基板2上设置的第二对位标记3在俯视方向上的形状相同，可以有效提高并检测对盒的精度。
第二对位标记3的厚度与第一基板和第二基板对盒形成的液晶盒的盒厚相同，第二对位标记3可以对封框胶进行完全的遮挡，可以阻止液晶与封框胶接触，降低基板内部液晶扩散对周边封框胶的冲击，防止断胶和避免未固化的封框胶对液晶造成的污染。封框胶内含有支撑组分，支撑组分包括硅球、玻璃纤维或两者的混合。第二对位标记3的厚度与第一基板1和第二基板2对盒后形成的液晶盒的厚度相同，可以起到支撑的作用，可以减少封框胶内支撑组分的用量，例如，封框胶中硅球的质量百分含量大于等于0且小于等于1％。
需要说明的是，第一对位标记的图案可以设置在第一基板或第二基板上，并与另一基板上设置的第二对位标记相匹配。
