现有显示面板的母板在切割过程中，切割道附近容易产生裂纹，该裂纹向显示面板的内部延伸，若显示面板不具有一定的防护措施，面内结构将受到损伤，从而影响显示质量。因此，本申请提出了一种显示面板以解决上述技术问题。
请参阅图1，图1为本申请显示面板的第一种俯视结构图。
所述显示面板100包括显示区10、围绕所述显示区10设置的裂纹防护区20、以及位于所述裂纹防护区20外围的切割区30。
请参阅图2，图2为本申请显示面板的第一种结构图。
所述显示区10内设置有衬底11、位于所述衬底11上的阵列层12、及位于所述阵列层12上的平坦层13。
所述裂纹防护区20内设置有所述衬底11、位于所述衬底11上的支撑构件21、及位于所述支撑构件21上的所述平坦层13。
所述裂纹防护区20内还设置有环绕所述显示区10且位于所述衬底11内的凹槽22，所述支撑构件21位于所述凹槽22内。
在本实施例中，所述支撑构件21远离所述衬底11一侧的表面在垂直于所述衬底11方向上的高度不超过所述衬底11与所述阵列层12的接触面在垂直于所述衬底11方向上的高度。
请参阅图2，在所述显示区10内，所述衬底11可以至少包括第一基板111及位于所述第一基板111上的第二基板112。所述第一基板111与所述第二基板112由不同蚀刻率的材料构成。
在本实施例中，所述第一基板111可以由柔性的有机材料构成，例如括聚酰亚胺（PI）等。所述第二基板112可以由刚性的无机材料构成，例如石英基板、树脂基板等。
在本实施例中，上述衬底11可以由多层所述第一基板111及所述第二基板112层叠设置，本申请不作具体限制。
所述阵列层12可以包括多个薄膜晶体管120120，所述薄膜晶体管12021可以为蚀刻阻挡型、背沟道蚀刻型或顶栅极晶体管等中的一种结构，具体没有限制。

请参阅图2，在所述切割区30内，该区域的所述衬底11可以与所述显示区10的衬底11相同，由所述第一基板111及所述第二基板112、或者层叠设置的所述第一基板111及所述第二基板112。
在所述衬底11上设置有多层膜层结构，例如缓冲层、栅绝缘层122、层间介质层123、以及位于层间介质层123上的平坦层13。
在本实施例中，所述切割区30内的膜层结构与显示区10内对应的膜层结构在同一道工艺中形成。
请参阅图2，在所述裂纹防护区20内，该区域的衬底11由所述第一基板111及所述第二基板112构成。
在本实施例中，所述凹槽22位于所述第一基板111内。
所述支撑构件21远离所述第一基板111一侧的表面在垂直于所述衬底11方向上的高度不超过所述第一基板111与所述第二基板112的接触面在垂直于所述衬底11方向上的高度。
在本实施例中，位于所述裂纹防护区20的所述第二基板112包括第一开口1121，所述第一开口1121在所述第一基板111上的正投影位于所述凹槽22内。
本区域的衬底11可以通过干法蚀刻工艺在所述第一基板111上形成所述凹槽22、以及在所述第二基板112上形成第一开口1121。根据所述第一基板111与所述第二基板112不同的蚀刻速率形成如图1所示的团。
在本实施例中，所述干法蚀刻工艺可以利用氧气、四氟化碳、六氟化硫等中的一种或其组合气体对所述衬底11进行蚀刻。
请参阅图2、以及图3~6，在所述显示区10至所述裂纹防护区20的方向上，所述第二基板112超过所述凹槽22边界，且向所述支撑构件21的中轴线延伸。

在本实施例中，a大于或等于0.5微米。
在本实施例中，所述第一基板111、所述第二基板112、及所述支撑构件21形成位于所述凹槽22内的镂空区23。
所述支撑构件21包括至少一无机膜层。所述支撑构件21可以通过单独的工艺在所述凹槽22内形成。
在本实施例中，所述支撑构件21中的至少一无机膜层与所述阵列层12中对应膜层在同一道工艺中形成。

在本实施例中，为了工艺的的简洁，所述支撑构件21内的膜层结构与所述阵列层12中的绝缘膜层相同。
在本实施例中，所述支撑构件21的厚度可以与所述阵列层12中无机膜层的厚度相同。
请参阅图3~6，图3~6为所述凹槽22的剖面简图。
所述凹槽22的剖面形状可以为长方形、正梯形、倒梯形或者小半圆等中的一种。
由于所述凹槽22围绕所述显示区10设置，因此所述凹槽22的剖面图可以为上述形状的组合，本申请不作具体限制。
请参阅图2~6，在所述显示面板100的俯视图方向上，所述支撑构件21可以与所述第二基板112不具有重叠部分24，二者之间可以存在一定间距。在显示面板100母板进行切割时，由于凹槽22内的支撑构件21与第二基板112上的无机层不连续，仅仅依靠位于支撑构件21上的平坦层13进行连接，而有机层的柔性无法进行力的传递，因此切割产生的裂纹无法从切割区30的膜层传递至显示区10内的阵列层12。
请参阅图7~9，在所述显示面板100的俯视图方向上，所述支撑构件21可以与所述第二基板112具有重叠部分2424。
在图2~6中，由于所述支撑构件21可以与所述第二基板112之间存在间隙，位于该间隙内的膜层结构为所述第一衬底11及所述平坦层13。而所述第一衬底11及所述平坦层13均为有机柔性材料，在没有相应无机膜层对该区域进行支撑的前提下，该区域易破损，导致面板的破片等技术问题。
请参阅图7，图7为本申请显示面板的第二种结构图。
所述重叠部分24包括第一重叠部分241，所述支撑构件21靠近所述显示面板100显示区10的一端与所述第二基板112形成第一重叠部分241。所述支撑构件21远离所述显示面板100显示区10的一端与所述第二基板112之间可以存在间隙。
请参阅图8，图8为本申请显示面板的第三种结构图。
所述重叠部分24包括第二重叠部分242，所述支撑构件21远离所述显示面板100显示区10的一端与所述第二基板112形成第二重叠部分242。所述支撑构件21靠近所述显示面板100显示区10的一端与所述第二基板112之间可以存在间隙。
请参阅图9，图9为本申请显示面板的第四种结构图。
所述重叠部分24包括第一重叠部分241和第二重叠部分242，所述支撑构件21靠近所述显示面板100显示区10的一端与所述第二基板112形成第一重叠部分241，所述支撑构件21远离所述显示面板100显示区10的一端与所述第二基板112形成第二重叠部分242。在本实施例中，所述支撑构件21与所述第二基板112之间不存在间隙。
图9中的实施例为图7和图8的结合，图7和图8中的实施例虽然能解决切割裂纹传递及支撑的技术问题，但是在技术效果上弱于图9中的实施例。但是图9中面板的工艺难度要大于图7和图8中的面板。
所述裂纹防护区20内的所述凹槽22在环绕所述显示区10的顺时针或逆时针方向上连续或非连续设置。
在所述显示面板100的俯视图方向上，所述凹槽22与所述显示面板100显示区10的边界平行设置，或者所述凹槽22在所述裂纹防护区20内以曲线或者折线设置。
请参阅图10，图10为本申请显示面板的第二种俯视结构图。
本实施例中位于所述裂纹防护区20内的虚线为所述凹槽22非连续设置的简图。所述虚线可以与所述显示区10外围边界平行设置或非平行设置。
在本申请的显示面板100中，在所述显示区10至所述裂纹防护区20的方向上，所述裂纹防护区20内设置有至少一所述凹槽22。
请参阅图11，图11为本申请显示面板的第三种俯视结构图。
所述裂纹防护区20内设置有两圈非连续的位于靠近显示区10的第一圈凹槽51和远离所述显示区10的第二圈凹槽52。所述第一圈凹槽51可以与所述第二圈凹槽52错位设置，以避免上述凹槽22非连续设置时，切割应力从相邻两凹槽22之间的非凹槽22区向显示面板100内部传递。
在一种实施例中，所述凹槽可以以螺旋状在所述裂纹防护区内设置。上述螺旋状设置凹槽可以与所述显示区的边界平行或非平行。
本申请还提出了一种显示模组，其中，所述显示模组包括上述显示面板、及位于所述显示面板上的偏光片层、位于所述偏光片层上的盖板层。所述显示模组的工作原理与上述显示面板的相同或相似，本申请不再赘述。
本申请还提出了一种显示装置，其中，所述显示装置包括上述显示模组。所述显示装置的工作原理与上述显示模组相同或相似，本申请不再赘述。
本申请提出了一种显示面板及显示模组，包括显示区以及围绕所述显示区设置的裂纹防护区，在所述裂纹防护区的外围设置有切割区。所述裂纹防护区内设置有环绕所述显示区的凹槽，所述凹槽内设置有支撑构件。所述支撑构件远离所述衬底一侧的表面在垂直于所述衬底方向上的高度不超过所述衬底与所述阵列层的接触面在垂直于所述衬底方向上的高度。本申请通过在所述裂纹防护区内挖槽，并在凹槽内设置支撑构件，该支撑构件与阵列层中的无机膜层不接触。当面板进行切割时，面板内的无机层的非连续设计，使得无机层中的作用力无法向显示区传递，避免了裂纹对显示区的损伤，提高了，保证了产品的良率。
综上所述，虽然本申请已以优选实施例揭露如上，但上述优选实施例并非用以限制本申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为准。
