进一步的，请参阅图2以及图3，图2为本申请实施例提供的显示面板的结构示意图，图3为本申请实施例提供的显示面板的另一结构示意图。
其中，该显示面板100包括：发光基板10，以及设置在该发光基板10上的光阻层20；其中，在发光基板10与该光阻层20之间还设有散射层30，以使发光基板10发出的光线通过该散射层30从光阻层20射出，并使得透过光阻层20的外界光经过散射层30折射和/或反射后被光阻层20吸收。
可以理解，发光基板10所发出的光通过散射层30进行折射改变其原本的入射角度，并射入光阻层20，折射和/或反射后的光线经由光阻层20射出到显示面板100的外界。并且，当外界光经由光阻层20射入到散射层30后，散射层30可以将该光线折射和/或反射后射入光阻层20，并由该光阻层20吸收。
在一些实施例中，光阻层20包括彩色滤光片201以及黑色矩阵202，该彩色滤光片201与该黑色矩阵202交错排列，用于在彩色滤光片201上形成发光区2011，以使光线通过该散射层30从该发光区2011射出并使得透过发光区2011的外界光经过该散射层30折射和/或反射后被该黑色矩阵202吸收。
其中，彩色滤光片201用于滤除发光基板10发出光线的其他颜色，仅通过该彩色滤光片201所对应可通过颜色。黑色矩阵202用于吸收外界光线，外界光线可以包括有太阳光等一些从外部射到显示面板100内的光。
在一些实施例中，请参阅图4以及图5，图4为本申请实施例提供的显示面板的又一结构示意图，图5为本申请实施例提供的显示面板的再一结构示意图。图4及图5与图2及图3的区别在于：在该发光基板10与所述散射层30之间还设有封装薄膜层40，用于将光线经过该封装薄膜层40射入该散射层30，减小射入该散射层30的入射角度θ。
其中，封装薄膜层40可采用化学气相沉积（Chemical Vapor Deposition，CVD）的方式进行处理，封装薄膜层40可以保护发光基板10，并且发光基板10的化合物也可以在一定程度上改变发光基板10发出的光线路径。在光线经封装薄膜层40射出并射入散射层30时，可以减小其射入散射层30的入射角度θ。
其中，光阻层20包括彩色滤光片201以及黑色矩阵202，该彩色滤光片201与该黑色矩阵202交错排列，用于在彩色滤光片201上形成发光区2011，以使光线通过该散射层30从该发光区2011射出并使得透过发光区2011的外界光经过该散射层30折射和/或反射后被该黑色矩阵202吸收。
其中，彩色滤光片201用于滤除发光基板10发出光线的其他颜色，仅通过该彩色滤光片201所对应可通过颜色。黑色矩阵202用于吸收外界光线，外界光线可以包括有太阳光等一些从外部射到显示面板100内的光。
在一些实施例中，彩色滤光片201，散射层30以及封装薄膜层40的折射率满足彩色滤光片201的折射率大于散射层30的折射率且散射层30的折射率大于封装薄膜层40的折射率，以使所述光线依次经过封装薄膜层40、散射层30与彩色滤光片201的发光区2011，并从发光区2011射出。当满足上述的折射条件时，从发光基板10发出的光依次通过封装薄膜层40、散射层30以及彩色滤光片201，从发光基板10射出光线射入每层的入射角会依次变小，以使得发光基板10所发出的光线尽可能多的射出显示面板100外。
在一些实施例中，封装薄膜层40由氮氧化硅组成。
一般来说，封装薄膜层40中常用的无机材料为氮化硅，其折射率约为1.8-1.9，并且，彩色滤光片201的折射率约为1.6-1.7，难以满足彩色滤光片201的折射率大于散射层30的折射率且散射层30的折射率大于封装薄膜层40的折射率这种折射条件，因此，在本申请实施例中，可以将封装薄膜层40中的无机材料换为氮氧化硅，氮氧化硅的折射率约为1.49-1.51，并且，氮氧化硅的光线透过率也高于氮化硅。
在一些实施例中，如图6所示，图6为本申请实施例提供的显示面板的另又一结构示意图。
发光基板10包括有机发光二极管（organic light emitting diode, OLED）的子像素101，发光区2011与该OLED器件的子像素101相对设置，且相对设置的该子像素101的颜色和该发光区2011对应的彩色滤光片201的颜色相同。
在一些实施例中，OLED器件的子像素101包括红、绿、蓝三种颜色，发光区2011对应的彩色滤光片201透过红、绿、蓝三种颜色中的一种。
其中，OLED器件上的子像素101包括有红、绿、蓝三种颜色，通过OLED器件的发光层发出对应该子像素101的颜色，并且，沿着Y轴的负方向上设有对应该子像素101颜色的彩色滤光片201，即红色的子像素101对应红色的彩色滤光片201，绿色的子像素101对应绿色的彩色滤光片201，即蓝色的子像素101对应蓝色的彩色滤光片201。比如，在同一Y轴方向上，存在有子像素101的出光颜色为红色，那么其对应的彩色滤光片201为只能通过红色光线，而其他颜色的光线将被滤除。因此，OLED器件上的子像素101与其颜色相对应的彩色滤光片201在同一Y轴方向上设置。
具体的，所述OLED器件包括阳极、空穴传输层、发光层、电子传输层以及阴极（图中均未示出）等。当电力供应至适当电压时，正极空穴与阴极电荷就会在发光层中结合，产生光亮，从而产生红、绿和蓝 RGB 三原色。
本申请实施例提供的显示面板100，包括发光基板10，以及设置在所述发光基板10上的光阻层20；其中，在所述发光基板10与所述光阻层20之间还设有散射层30，以使所述发光基板10发出的光线通过所述散射层30从所述光阻层20射出，并使得透过所述光阻层20的外界光经过所述散射层30折射和/或反射后被所述光阻层20吸收，从而提高了显示面板100的出光效率以及对比度。
进一步的，如图7所示，图7为本申请实施例提供的显示面板的另再一结构示意图。
在一些实施例中，封装薄膜层40分为多个子封装薄膜层401，该子封装薄膜层401与OLED器件的子像素101相对设置。
在一些实施例中，子封装薄膜层401之间设有水氧阻隔层402，用于阻挡水以及氧气进入所述显示面板100。
由于光线是通过OLED器件的子像素101上方射出，因此，在除子像素101同一Y轴方向上的位置不需要设置无机材料。因此，可以沿Y轴负方向在子像素101的上方设置与子像素101在X轴的宽度相等的子封装薄膜层401，其中，封装薄膜层401其X轴的宽度也可大于子像素101在X轴的宽度。并且，为了防止工艺流程中水以及氧气跑入封装薄膜层40，可在两两设置的子封装薄膜层401之间设置水氧阻隔层402，防止水以及氧气进入显示面板100中。
本申请实施例提供的显示面板100，包括发光基板10，以及设置在所述发光基板10上的光阻层20；其中，在所述发光基板10与所述光阻层20之间还设有散射层30，以使所述发光基板10发出的光线通过所述散射层30从所述光阻层20射出，并使得透过所述光阻层20的外界光经过所述散射层30折射和/或反射后被所述光阻层20吸收，从而提高了显示面板100的出光效率以及对比度，并有效的防止水以及氧气进入显示面板100内。

发光基板10，以及设置在所述发光基板10上的光阻层20；其中，
在所述发光基板10与所述光阻层20之间还设有散射层30，以使所述发光基板10发出的光线通过所述散射层30从所述光阻层20射出，并使得透过所述光阻层20的外界光经过所述散射层30折射和/或反射后被所述光阻层20吸收，其中，所述发光基板10与所述散射层30之间设有封装薄膜层40，用于将所述光线经过所述封装薄膜层40射入所述散射层30，以使所述发光基板10发出的光线依次射入所述封装薄膜层40、所述散射层30以及所述光阻层20的入射角度逐渐减小。
为了进一步描述本申请，下面从显示面板的制作方法的方向进行描述。

在所述发光基板与所述光阻层之间形成一散射层，以使所述发光基板发出的光线通过所述散射层从所述光阻层射出，并使得透过所述光阻层的外界光经过所述散射层折射和/或反射后被所述光阻层吸收。
