具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
请参考图2和图4，本公开实施例提供的一种显示基板，包括：基底1，以及设置在基底1上的器件层和绝缘层，基底1包括显示区域和位于显示区域周侧的非显示区域；
其中，绝缘层中与非显示区域对应的部位设有至少一个阻挡墙，每个阻挡墙与基底的一个侧边的边部一一对应，即每个阻挡墙位于基底1的一个侧边11的边部上；具体的，每一个对应有阻挡墙的侧边11的边部中，阻挡墙包括多个沿侧边11的延伸方向排列且延伸方向与侧边11垂直的阻挡条2，每个阻挡条2具有沿与侧边11垂直的方向延伸的锯齿形结构，‘沿与侧边11垂直的方向延伸的锯齿形结构’，即，锯齿形结构的多个齿部沿与侧边11垂直的方向排列，每个齿部凸起的方向与其排列方向交叉。
上述显示基板，在绝缘层中与基底1的非显示区域对应的部位设置阻挡墙，阻挡墙与基底1的侧边11的边部对应，并包括多个延伸方向与基底1侧边11垂直的阻挡条2，每个阻挡条2具有沿与侧边11垂直的方向延伸的锯齿形结构，当显示基板侧面受到垂直于该侧面的外力时，阻挡条2朝向外力的表面形成与该外力接触的接触面，由于每个阻挡条2具有锯齿形结构，阻挡条2朝向外力的接触面为与外力不垂直的表面，即外力方向与阻挡条2的接 触面不垂直，则外力施加于阻挡条2时，根据力学知识易知，外力将分解为与阻挡条2的接触面垂直的一个垂直分力和与接触面平行的一个平行分力，且这两个分力均小于该外力，则阻挡条2的锯齿形结构将该外力分解为比该外力小且朝向其他方向的两个分力，这样可能就无法达到产生裂纹的最小应力，进而可以在显示基板切割、取放或转移过程中缓解产生裂纹的状况；如果外力过大，以致将施加的外力分解之后形成的分力仍然可以达到显示基板产生裂纹的临界应力，此时在分力作用下产生的裂纹将沿着该分力方向延伸，而该裂纹延伸遇到下一部分锯齿形结构时该分力将会被再次分解为两个相对较小、且方向不同的分力，如此下来，裂纹的冲击力和能量逐渐被分散减弱，很容易被消耗殆尽，因此裂纹很难进行发展和延伸；并且由于阻挡条2具有锯齿形结构，在显示基板平面内，沿阻挡条2的延伸方向，锯齿形结构的阻挡条2的实际长度相比于直线距离更长，而裂纹在扩展的过程中会消耗外力的能量，阻挡条2的实际长度较长则将消耗的外力能量更多，从而可以有效阻止裂纹的扩展，使裂纹在显示基板平面内发展的直线距离很短。
因此，上述显示基板中，具有锯齿形结构的阻挡条2可以有效缓解显示基板在切割、取放或转移过程中周侧侧面受到外力而产生裂纹的状况，且当受外力过大时，也可以有效阻止裂纹扩展，提高面板显示质量。
具体地，器件层可以包括薄膜晶体管的栅极、有源层、源漏电极层等金属或半导体层，绝缘层可以包括位于器件层之间的层间绝缘层和栅绝缘层，阻挡墙可以设置在层间绝缘层，也可以设置在栅绝缘层，可选地，为增强对外力的阻挡效果，可以在层间绝缘层和栅绝缘层上均设置阻挡墙。
具体地，上述显示基板中，每个阻挡条2沿垂直于侧边11的方向的尺寸d为40μm～60μm，即，在设置有阻挡墙的侧边11的边部，沿垂直于对应的侧边11的方向，每个阻挡条2的一端到另一端的直线距离长度设置为40μm～60μm，由于每个阻挡条2具有锯齿形结构，则每个阻挡条2的实际长度必然大于一端到另一端的直线距离，根据实际设计需求，每个阻挡条2一端到另一端的直线距离选择在40μm～60μm范围内，可以更有效的阻挡裂 纹延伸，提高显示效果。
为增强阻挡墙整体的阻挡效果，如图2和图4所示，各阻挡条2在一个与基底1垂直、且与阻挡条2的排列方向平行的平面上的正投影中，每相邻的两个阻挡条2的正投影部分交叠，即，在每个阻挡条2所在的平面内，沿垂直于阻挡条2的排列方向看，每相邻的两个阻挡条2之间部分交错设置，相互交叠遮挡，没有空隙；换句话说，显示基板的一个侧边11的边部所对应的一个阻挡墙中，各阻挡条2在一个与基底1垂直、且与该侧边11平行的平面上的正投影中，每相邻的两个阻挡条2的正投影部分交叠。因此，当外力施加于该设置有阻挡墙的侧边11时，无论外力施加在侧边11的任何位置，均有阻挡条2与外力相对以对该外力进行阻挡，因此可以有效提高阻挡墙的阻挡效果，当有裂纹产生时，有效的阻挡裂纹扩展。
其中，上述阻挡条2的锯齿形结构可以有多种设计选择，如：
一种实施方式中：
如图2所示，锯齿形结构包括至少一个“S”形单元条，其中，每个“S”形单元条包括第一端和第二端，当锯齿形结构包括多个“S”形单元条时，沿阻挡条2的延伸方向，前一个“S”形单元条的第二端与后一个“S”形单元条的第一端连接，多个“S”形单元条顺次连接形成齿尖比较圆滑的锯齿形结构，如图3所示，由于“S”形单元条的外侧面为曲面，与施加于侧边11的外力F不垂直，因此外力传至阻挡条2上时，“S”形单元条可以将该外力F分解为朝向其他不同方向且均小于该外力的两个分力F 1、F 2，具体的，F 1、F 2可以是分别沿“S”形单元受力面的切向和垂直方向的两个分力，F 1、F 2均小于F，很可能无法达到产生裂纹的最小应力，进而直接阻断裂纹的发生，另外，即使F 1和/或F 2能达到产生裂纹的最小应力，致使沿F 1和/或F 2方向产生裂纹，该裂纹延伸遇到下一部分锯齿形结构时其冲击力也会再次被分解为两个相对较小的其它方向的分力，如此下来，裂纹的冲击力和能量逐渐被分散减弱，很容易被消耗殆尽，因此裂纹很难进行发展和延伸，且沿垂直于侧边11方向的直线发展距离也会很短，所以可以有效阻止裂纹的扩展，使裂纹在 显示基板平面内发展的直线距离较短，避免影响显示效果。
另一种实施方式中：
如图4所示，锯齿形结构包括至少一个“V”形单元条，其中，每个“V”形单元条包括第一自由端和第二自由端，当锯齿形结构包括多个“V”形单元条时，沿阻挡条2延伸方向，前一个“V”形单元条的第二自由端与后一个“V”形单元条的第一自由端连接，多个“V”形单元条顺次连接形成齿尖比较尖锐的锯齿形结构，如图5所示，由于“V”形单元条与施加外力的侧边11对应的侧面为倾斜面，与施加于侧边11的外力F不垂直，因此外力传至阻挡条2上时，“V”形单元条可以将该外力F分解为朝向其他方向且均小于该外力的两个分力F 3、F 4，具体的，F3、F4可以是分别沿“V”形单元的倾斜面和垂直于倾斜面两个方向上的分力，F3、F4均小于F，很可能无法达到产生裂纹的最小应力，进而直接阻断裂纹的发生，即使F3和/或F4能达到产生裂纹的最小应力，致使沿F3和/或F4方向产生裂纹，该裂纹延伸遇到下一部分锯齿形结构时其冲击力也会再次被分解为两个相对较小的其它方向的分力，如此下来，裂纹的冲击力和能量逐渐被分散减弱，很容易被消耗殆尽，因此裂纹很难进行发展和延伸，且沿垂直于侧边11方向的直线发展距离也会很短，所述可以有效阻止裂纹的扩展，使裂纹在显示基板平面内的发展的直线距离较短，避免影响显示效果。
上述方式中，“V”形单元条中两个斜边(两个倾斜面)所呈角度为90°～120°，为使形成的阻挡条2的阻挡效果更佳，可以根据实际设置在90°～120°范围内选择“V”形单元条中两个斜边所呈角度。
具体地，为提高对显示基板整体的保护强度，可以在上述基底1中，每相对的两个侧边的边部均设置阻挡墙，对显示基板的保护效果更好，可以更有效的避免裂纹产生，提高显示效果。
上述显示基板的阻挡墙中，阻挡条2间隔均匀排列，多个阻挡条2等间距的排列，有利于提高阻挡效果，且便于制备。
基于同一发明思想，本公开实施例还提供了一种显示面板，包括上述实 施例中提供的任意一种显示基板。
另外，本公开实施例还提供了一种显示装置，包括实施例中提供的任意一种显示面板。
显然，本领域的技术人员可以对本公开实施例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。
