如图1所示，该衬底1可以为刚性衬底。其中，该刚性衬底可以为玻璃衬底或PMMA(Polymethyl methacrylate，聚甲基丙烯酸甲酯)衬底等。当然，该衬底1还可以为柔性衬底。其中，该柔性衬底可以为PET(Polyethylene terephthalate，聚对苯二甲酸乙二醇酯)衬底、PEN(Polyethylene naphthalate two formic acid glycol ester，聚萘二甲酸乙二醇酯)衬底或PI(Polyimide，聚酰亚胺)衬底。
如图1所示，本公开的显示面板还可以包括有源层8、栅绝缘层2、栅电极层9、层间绝缘层3、第一源漏电极层5。该有源层8可以设于衬底1上。该栅绝缘层2可以设于衬底1上，并覆盖有源层8。该栅电极层9可以设于栅绝缘层2远离衬底1的一侧。该层间绝缘层3可以设在栅绝缘层2上，并覆盖栅电极层9。该第一源漏电极层5可以设在层间绝缘层3上，且第一源漏电极层5的部分图案可以经由穿过层间绝缘层3和栅绝缘层2的过孔连接至有源层8。
如图1所示，本公开的显示面板还可以包括第一平坦化层16和第二源漏电极层6。该第一平坦化层16覆盖第一源漏电极层5以及层间绝缘层3。该第二源漏电极层6可以设于第一平坦化层16上，该第二源漏电极层6的部分图案可以经由穿过第一平坦化层16的过孔与上述的第一源漏电极层5电连接。本公开的显示面板还可以包括第二平坦化层17。该第二平坦化层17可以覆盖第二源漏电极层6。本公开实施方式的显示面板可以包括像素电路。上述的有源层8、栅绝缘层2、栅电极层9、层间绝缘层3、第一源漏电极层5可以构成驱动晶体管。
如图1所示，多个子像素18可以包括红色子像素、绿色子像素以及蓝色子像素。各子像素18可以包括层叠设置的第一电极10、发光层11以及第二电极12。该发光层11可以为有机电致发光层，当然，也可以为量子点发光层，本公开实施方式对此不做特殊限定。该第一电极10可以为阳极，该第二 电极12可以为阴极，但本公开不限于此。如图7所示，该发光层11可以包括内部区域200以及围绕内部区域200的边缘区域300。以发光层11呈矩形为例，该边缘区域300可以为矩形环。该边缘区域300的宽度与发光层11的长度或宽度的比值可以为1/10-1/3。需要说明的是，沿着边缘区域300的延伸方向，该边缘区域300具有均匀的宽度，也就是说，边缘区域300在发光层11的长度方向上的宽度与边缘区域300在发光层11的宽度方向上的宽度相同。具体地，该边缘区域300的宽度F可以大于等于5μm或小于等于10μm，进一步地，该边缘区域300的宽度F可以大于等于5μm且小于等于10μm，例如5μm、7μm、8μm、9μm、10μm等。
如图1所示，本公开的显示面板还可以包括像素界定层13。该像素界定层13可以设于第二平坦化层17背向衬底1的一侧，且设有多个像素开口。上述的第一电极10可以设于像素开口内，该发光层11可以设于第一电极10背向衬底1的一侧，该第二电极12可以设于发光层11背向衬底1的一侧。该第一电极10经由穿过第二平坦化层17的过孔与第二源漏电极层6电连接。多个子像素18可以共用一个第二电极12。本公开的显示面板还可以包括封装结构14。该封装结构14可以覆盖子像素18。其中，该封装结构14可以包括层叠设置的第一无机封装层、有机封装层以及第二无机封装层，该第二无机封装层设于第一无机封装层背向衬底的一侧。
如图1所示，该第一结构层4设于发光层11的出光侧。该发光层11的出光侧可以为发光层11背向衬底1的一侧。其中，该第一结构层4可以设于上述的封装结构14背向衬底1的一侧。举例而言，该微透镜401可以设于第二无机封装层背向衬底1的表面。该微透镜401的折射率可以与第二无机封装层的折射率相同或大致相同，当然，也可以不同。该微透镜401的折射率与第二无机封装层的折射率相同或大致相同，即微透镜401的折射率以及第二无机封装层的折射率在误差允许范围内等于预设值，该误差允许范围可以为±5％。在本公开其它实施方式中，该微透镜401可以设于一基底15上， 该基底15设于封装结构14背向衬底1的表面。该基底15的材料可以为玻璃等。该第一结构层4可以包括多个微透镜401。该微透镜401可以为凸透镜结构，但本公开不限于此。该多个微透镜401可以构成多个透镜组100。各透镜组100内可以包含多个微透镜401。多个透镜组100与多个子像素18一一对应。此外，该微透镜401的材料可以包括光刻胶。
如图2和图3所示，设于第二区域500的微透镜401的密度可以小于设于第一区域400的微透镜401的密度，如此设置，可以减弱发光层11的边缘区域300的光提取效果。具体地，设于第二区域500的相邻的两个微透镜401之间的距离大于设于第一区域400的相邻的两个微透镜401之间的距离，例如，如图2所示，L3大于L1，L3大于L2。进一步地，从透镜组100的中心到透镜组100的边缘，微透镜401的密度逐渐减小。具体地，如图2所示，从透镜组100的中心到透镜组100的边缘，相邻的两个微透镜401之间的距离逐渐增大，例如L1<L2<L3。其中，相邻的两个微透镜401之间的距离可以大于微透镜401的直径。此外，本公开的多个微透镜401可以为图3所示的正交分布形态，也可以为图4所示的蜂窝状排列形态。
如图5和图6所示，以微透镜401为凸透镜结构为例，设于第二区域500的微透镜401的矢高H与直径D的比值小于设于第一区域400的微透镜401的矢高与直径的比值。该微透镜401的矢高指的是微透镜401在垂直于衬底1的方向上的最大高度。该微透镜401的直径指的是微透镜401在衬底1上的圆形正投影的直径。其中，多个微透镜401的直径可以相同或大致相同，但本公开不限于此。多个微透镜401的直径相同或大致相同即任一微透镜401的直径在误差允许范围内等于预设值，该误差允许范围可以为±5％。举例而言，设于第二区域500的微透镜401的矢高与直径的比值可以大于等于0.1或小于等于0.3，进一步地，设于第二区域500的微透镜401的矢高与直径的比值可以大于等于0.1且小于等于0.3，例如0.1、0.2、0.3等；设于第一区域400的微透镜401的矢高与直径的比值可以大于等于0.4或小于等于0.7，进一步 地，设于第一区域400的微透镜401的矢高与直径的比值可以大于等于0.4且小于等于0.7，例如0.4、0.5、0.6、0.7等，如此设置，不仅可以提高发光层11的光提取效果，同时还可以降低发光层11的边缘漏光现象。其中，微透镜401的矢高与直径的比值越大，微透镜401边缘点的切线E与衬底1的夹角α越大，可以提高光提取效果。进一步地，从透镜组100的中心到透镜组100的边缘，微透镜401的矢高与直径的比值逐渐减小。
如图1所示，本公开实施方式的显示面板还可以包括平坦层7。该平坦层7可以设于第一结构层4背向衬底1的一侧，且覆盖第一结构层4。该平坦层7的折射率可以小于微透镜401的折射率。该平坦层7可以包括胶体材料，但本公开实施方式不限于此。
本公开实施方式还提供一种显示装置。该显示装置可以包括上述任一实施方式所述的显示面板。该显示装置可以为手机，当然，也可以为平板电脑、电视等。由于本公开实施方式的显示装置中的显示面板同上述显示面板的实施方式中的触控面板相同，因此，其具有相同的有益效果，在此不再赘述。
以上所述仅是本公开的较佳实施方式而已，并非对本公开做任何形式上的限制，虽然本公开已以较佳实施方式揭露如上，然而并非用以限定本公开，任何熟悉本专业的技术人员，在不脱离本公开技术方案的范围内，当可利用上述揭示的技术内容做出些许更动或修饰为等同变化的等效实施方式，但凡是未脱离本公开技术方案的内容，依据本公开的技术实质对以上实施方式所作的任何简单修改、等同变化与修饰，均仍属于本公开技术方案的范围内。
