 本发明的实施方式
下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
在本申请的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个特征。在本申请的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。

本申请实施例提供一种显示面板，显示面板包括显示区域以及位于显示区域外侧的非显示区域，显示面板包括第一缓冲层以及多个显示区膜层，第一缓冲层位于非显示区域，第一缓冲层柔性连接多个显示区膜层中至少两个显示区膜层。本申请实施例的显示面板可以应用于各种显示装置中。以下进行详细说明。
请参阅图1，图1是本申请实施例提供的一种显示面板的第一实施例平面结构示意图；图2是图1中显示面板的剖面结构示意图。其中，图2为图1中显示面板沿剖物线L剖开的剖面结构示意图。
本实施例中，显示面板10包括显示区域11以及位于显示区域11外侧的非显示区域12。显示面板10包括第一缓冲层16和3个显示区膜层。3个显示区膜层分别为第一显示区膜层13、第二显示区膜层14以及第三显示区膜层15，3个显示区膜层在显示区域11堆叠设置。第一缓冲层16位于非显示区域12，第一缓冲层16柔性连接第一显示区膜层13和第二显示区膜层14。其中，柔性连接可以是弹性连接、弹塑性连接以及塑性连接等，本申请对此不作限定。当显示面板10沿着M方向或者其反方向弯折时，第一显示区膜层13和第二显示区膜层14之间产生相对位移，进而产生层间剪力。此时，由于第一缓冲层16柔性连接第一显示区膜层13和第二显示区膜层14。一方面，第一缓冲层16内部产生与相对位移方向相反的反作用力，显然，当相对位移固定时，第一缓冲层16内部的反作用力抵抗了部分由于膜层相对位移产生的力，从而减小了显示区膜层间的层间应力，避免了显示面板10的膜层发生开裂。另一方面，第一缓冲层16跟随显示区膜层的相对位移发生变形，避免了显示面板10的膜层断裂。
在一个优选的实施例中，柔性连接为弹性连接。当导致显示区膜层发生相对位移的外力解除后，第一缓冲层16及时将各显示区膜层恢复至原状，避免显示面板10在多次弯折后出现膜层开裂。
在其他实施例中，第一缓冲层16也可以柔性连接第一显示区膜层13和第二显示区膜层15，或者柔性连接第二显示区膜层14和第三显示区膜层15，或者柔性连接第一显示区膜层13、第二显示区膜层14以及第三显示区膜层15，本申请对此不作限定。
在更多的实施例中，显示面板10也可以包括2个、4个或者更多个显示区膜层，第一缓冲层16柔性连接多个显示区膜层中至少两个显示区膜层，本申请对此不作限定。例如，显示面板10包括5个显示区膜层，第一缓冲层16柔性连接5个显示区膜层中的3个显示区膜层。
区别于现有技术，本申请提供一种显示面板，显示面板包括显示区域以及位于显示区域外侧的非显示区域，显示面板包括第一缓冲层以及多个显示区膜层，第一缓冲层位于非显示区域，第一缓冲层柔性连接多个显示区膜层中至少两个显示区膜层。本申请通过位于显示区域的第一缓冲层柔性连接至少部分显示区膜层，在显示区膜层发生相对位移的时候，第一缓冲层能够产生与显示区膜层相对位移方向相反的力，能够抵抗显示区膜层之间的剪切应力，避免显示面板发生开裂。
为了具体的描述本申请显示面板的结构，请参阅图3，图3是本申请实施例提供的一种显示面板的第二实施例剖面结构示意图。

本实施例中，第一缓冲层26为光刻胶、橡胶、丙烯酸酯、聚氨酯以及硅胶中的任意一种。
进一步的，在背板层28、显示层23、偏光片24、触控层25以及盖板层27中，彼此相邻的两膜层的接触面通过粘结材料29连接。优选的，粘结材料29为光刻胶。在其他实施例中，粘结材料29也可以为其他材料，本申请对此不作限定。通过粘结材料29将彼此相邻的两膜层的接触面连接，能够增强膜层之间可承受的层间剪力，避免了膜层之间发生开裂。
