本申请实施例提供一种显示面板及显示装置，下文进行详细说明。需说明的是，以下实施例的描述顺序不作为对实施例优选顺序的限定。
请参照图1，本申请实施例一提供一种显示面板100，其包括面板主体11、偏光层12和盖板模组13。
面板主体11包括功能区sx和围绕功能区sx的至少一部分的显示区AA。偏光层12设置在面板主体11的出光侧。盖板模组13设置在偏光层12远离面板主体11的一侧。
盖板模组13对应于功能区sx的部分具有总面内相位差值。总面内相位差值小于等于100纳米或大于等于7500纳米。
在本申请实施例一的显示面板100将偏光层12之上的盖板模组13的总面内相位差值设置为小于等于100纳米或大于等于7500纳米的设置，以改善相片出现彩虹条纹的情况，进而提高摄像质量。
需要说明的是，总面内相位差值可以为各个膜层的面内相位差值之和。最终的总面内相位差值以对盖板模组13的实测数值为准。
可选的，偏光层12可以形成在面板主体11上；也可以通过胶体贴附在面板主体11上。
可选的，盖板模组13可以仅对应于功能区sx的部分的总面内相位差值小于等于100纳米或大于等于7500纳米；也可以是盖板模组13对应于显示区的部分的总面内相位差值小于等于100纳米或大于等于7500纳米，也即盖板模组13对应于显示区的部分的也具有所述总面内相位差。
可选的，总面内相位差值可以是100纳米、95纳米、80纳米、70纳米、60纳米、50纳米、40纳米、30纳米、20纳米、10纳米、7500纳米、8000纳米、8500纳米、9500纳米、10000纳米或15000纳米等。

需要说明的是，面内相位差值与膜层的生产过程有关，一般的膜层使用熔融流延工艺成膜，可得到一种无拉伸、非定向的膜层，此时该膜层不存在明显的取向。如果将该膜层进行单轴或双轴的拉伸处理后，膜层具有了取向方向，此时具有取向方向的膜层便具有了面内相位差值。
可选的，盖板模组13包括第一光学胶层131和第一柔性层132。
第一光学胶层131设置在偏光层12远离面板主体11的一侧。第一柔性层132设置在第一光学胶层131远离偏光层12的一侧。
其中，第一柔性层132的面内相位差值小于等于100纳米或大于等于7500纳米。
也即，第一柔性层132的面内相位差值可以是100纳米、95纳米、80纳米、70纳米、60纳米、50纳米、40纳米、30纳米、20纳米、10纳米、7500纳米、8000纳米、8500纳米、9500纳米、10000纳米或15000纳米等。
可选的，第一光学胶层131的面内相位差值为0。可选的，第一光学胶层131和第一柔性层132的数量均为一层。
可选的，第一柔性层132可以是单层膜层结构，也可以是由多层子膜层堆叠形成。可选的，第一柔性层132的厚度介于25微米-200微米之间，比如可以是25微米、50微米、100微米、150微米或200微米。
需要说明的是，第一柔性层132的厚度可根据实际情况的需求进行设置，比如显示面板100的弯折半径r=3毫米时，弯折200000次以上膜层无损坏，则可设置第一柔性层132的厚度介于25微米-100微米之间，比如可以是25微米、50微米、80微米或100微米。
可选的，第一柔性层132的材料包括透明聚酰亚胺（CPI）、聚对苯二甲酸乙二醇酯（PET）或三醋酸纤维素（TAC）中的至少一种。
需要说明的是，在本实施一中，第一柔性层132的材料包括透明聚酰亚胺（CPI）、聚对苯二甲酸乙二醇酯（PET）、三醋酸纤维素（TAC）中的一种。当然第一柔性层132也可以是其他材料，此处不再赘述。
可选的，第一光学胶层131的厚度介于20微米-60微米之间，比如可以是20微米、30微米、40微米、50微米或60微米。
可选的，显示面板100还可以包括依次设置在面板主体11远离偏光层12一面上的背板14、泡沫层15和支撑片16。
其中，背板14、泡沫层15和支撑片16上设置有开孔，所述开孔对应于功能区sx。该开孔可贯穿背板14、泡沫层15和支撑片16。
在一些实施例中，所述开孔贯穿泡沫层15和支撑片16。背板14的面内相位差值为0。
请参照图2，实施例二的显示面板100与实施例一的显示面板100的不同之处在于：盖板模组13还包括第二光学胶层133和硬化层134。
第二光学胶层133设置在第一柔性层132远离偏光层12的一侧。硬化层134设置在第二光学胶层133远离偏光层12的一侧。
其中，第一柔性层132和硬化层134的叠层结构的面内相位差值小于等于100纳米或大于等于7500纳米。
也即，第一柔性层132和硬化层134的叠层结构的面内相位差值可以是100纳米、95纳米、80纳米、70纳米、60纳米、50纳米、40纳米、30纳米、20纳米、10纳米、7500纳米、8000纳米、8500纳米、9500纳米、10000纳米或15000纳米等。
可选的，硬化层134的厚度小于第一柔性层132的厚度。
硬化层134起到保护面板主体11的作用，也可避免第一柔性层132被刮破。将硬化层134的厚度设置为小于第一柔性层132的厚度，以确保显示面板100的柔性。
硬化层134的厚度介于3微米-10微米之间，比如可以是3微米、5微米、7微米、9微米或10微米。
可选的，硬化层134可以是超薄玻璃（UTG）或其他硬性涂层。硬化层134的面内相位差值可以为0。请参照图3，实施例三的显示面板100与实施例二的显示面板100的不同之处在于：盖板模组13还包括第三光学胶层135和第二柔性层136。
第三光学胶层135设置在硬化层134远离偏光层12的一侧。第二柔性层136设置在第三光学胶层135远离偏光层12的一侧。
其中，第一柔性层132、硬化层134、第二柔性层136的叠层结构的面内相位差值小于等于100纳米或大于等于7500纳米。
也即，第一柔性层132、硬化层134、第二柔性层136的叠层结构的面内相位差值可以是100纳米、95纳米、80纳米、70纳米、60纳米、50纳米、40纳米、30纳米、20纳米、10纳米、7500纳米、8000纳米、8500纳米、9500纳米、10000纳米或15000纳米等。
可选的，硬化层134的面内相位差值可以为0或其他值。
可选的，第二柔性层136与第三光学胶层135的边缘平齐。
其中，第二柔性层136和第三光学胶层135先组合在一起，随后进行切边处理使得二者的边缘平齐，然后拿来贴在硬化层134上；相较于先涂第三光学胶层135，后贴第二柔性层136的工艺；本工艺更为简单，且贴合更为精准。
另外，第二柔性层136与第三光学胶层135的边缘平齐，使得第二柔性层136与硬化层134的贴合更为周全。
可选的，第一柔性层132和第二柔性层136的取向方向相差小于或等于15度。其中，二者的取向方向相差可以为15度、10度、5度或0度。
需要说明的是，柔性层的取向方向为柔性层被拉伸的方向。比如一第一柔性层132的被拉伸方向平行于二维坐标系的x轴，第二柔性层136的被拉伸方向与x轴相交，则第二柔性层136被拉伸的方向相较于x轴所偏转的角度为第一柔性层132和第二柔性层136的取向方向相差的度数。
另外，当两层柔性层进行层叠设置，若二者的取向方向相差小于或等于15度时，两层柔性层叠加的总面内相位差值大于任意一层柔性层的面内相位差值。若二者的取向方向相差大于15度时，两层柔性层叠加的总面内相位差值可以小于或等于任意一层柔性层的面内相位差值。
故任意两层第一柔性层132和第二柔性层136的取向方向相差小于或等于15度的设置，便于推断总面内相位差值的趋势，以提高制备效率。
可选的，第一柔性层132和第二柔性层136的取向方向相互平行。这样的设置便于提高总面内相位差值。
可选的，第一柔性层132和第二柔性层136的面内相位差值也可以相同。第一柔性层132和第二柔性层136的面内相位差值相同有助于降低光学效应的复杂性，便于改善摄像的彩虹纹问题。
在一些实施例中，也可以是第一柔性层132和第二柔性层136的面内相位差值不同。比如第一柔性层132的面内相位差值为0或5，第二柔性层136的面内相位差值为90纳米。
当盖板模组13的总面内相位差值小于或等于100纳米时，第一柔性层132和第二柔性层136均为低相位差值的柔性层。比如第一柔性层132和第二柔性层136的面内相位差值均小于或等于100纳米。
当盖板模组13的总面内相位差值大于或等于7500纳米时，第一柔性层132和第二柔性层136均为高相位差值的柔性层。比如第一柔性层132和第二柔性层136的面内相位差值均大于或等于2000纳米。
需要说明的是，相同材料的膜层经过不同的制备工艺，设置不同的膜层均可以得到不同的面内相位差值，比如PET材料的膜层可以是低面内相位差值的膜层，也可以是高面内相位差值的膜层。
其中，当第一柔性层132和第二柔性层136进行贴合时，第二柔性层136的取向方向与第一柔性层132的取向方向进行同向贴合，如图4所示。
第一柔性层132具有取向方向MD1和垂直于取向方向MD1的第二方向TD1；第二柔性层136具有取向方向MD2和垂直于取向方向MD2的第二方向TD2。故在贴合时，第一柔性层132的取向方向MD1与第二柔性层136的取向方向MD2同向贴合；第一柔性层132的第二方向TD2与第二柔性层136的第二方向TD2同向贴合。该贴合方式便于得到高面内相位值的叠构膜层。
请参照图5，实施例四的显示面板100与实施例三的显示面板100的不同，盖板模组13还包括第四光学胶层137和第三柔性层138。
第四光学胶层137设置在第二柔性层136远离偏光层12的一侧。
第三柔性层138设置在第四光学胶层137远离偏光层12的一侧。
其中，第一柔性层132、硬化层134、第二柔性层136、第三柔性层138的叠层结构的面内相位差值小于等于100纳米或大于等于7500纳米。
也即，第一柔性层132、硬化层134、第二柔性层136、第三柔性层138的叠层结构的面内相位差值可以是100纳米、95纳米、80纳米、70纳米、60纳米、50纳米、40纳米、30纳米、20纳米、10纳米、7500纳米、8000纳米、8500纳米、9500纳米、10000纳米或15000纳米等。
可选的，第三柔性层138的面内相位差值和第二柔性层136的面内相位差值相同。
可选的，第三柔性层138的取向方向与第二柔性层136的取向方向平行。
其中，当第三柔性层138和第二柔性层136进行贴合时，第二柔性层136的取向方向与第三柔性层138的取向方向进行同向贴合。
在一些实施例中，第三柔性层138和第二柔性层136的取向方向也可以是相差小于或等于15度。其中，二者的取向方向相差可以为15度、10度、5度或0度。
在一些实施例中，第三柔性层138和第二柔性层136的面内相位差值也可以不同。比如第三柔性层138的面内相位差值大于0，第二柔性层136的面内相位差值可以为0。当第二柔性层136的面内相位差值为0时，第二柔性层136没有明显的取向方向。
可选的，第一柔性层132、第二柔性层136和第三柔性层138的材料分别选自透明聚酰亚胺（CPI）、聚对苯二甲酸乙二醇酯（PET）或三醋酸纤维素（TAC）中一种，但不限于此。

其中，硬化层134和第一柔性层132的叠层结构的面内相位差值小于等于100纳米或大于等于7500纳米。
也即，第一柔性层132和硬化层134的叠层结构的面内相位差值可以是100纳米、95纳米、80纳米、70纳米、60纳米、50纳米、40纳米、30纳米、20纳米、10纳米、7500纳米、8000纳米、8500纳米、9500纳米、10000纳米或15000纳米等。
其中，本实施例五的显示面板100与实施例二的显示面板100的不同之处在于，硬化层134的位置不同。本实施例五的显示面板100将硬化层134设置在靠近偏光层12的一侧，使得硬化层134更接近显示面板100，以更好的保护显示面板100以及更好的提供支撑平面。
可选的，第一柔性层132与第一光学胶层131的边缘平齐。
其中，第一柔性层132与第一光学胶层131先组合在一起，随后进行切边处理使得二者的边缘平齐，然后拿来贴在硬化层134上；相较于先涂第一光学胶层131，后贴第一柔性层132的工艺；本工艺更为简单，且贴合更为精准。
另外，第一柔性层132与第一光学胶层131的边缘平齐，使得第一柔性层132与硬化层134的贴合更为周全。
请参照图7，实施例六的显示面板100与实施例五的显示面板100的不同之处在于：盖板模组13还包括第三光学胶层135和第二柔性层136。
第三光学胶层135设置在第一柔性层132远离偏光层12的一侧。

可选的，硬化层134的面内相位差值可以为0或其他值。
