如图1所示，所述显示面板100还包括阳极5。所述阳极5相互间隔设置于所述基板的一侧的表面上。具体的，所述薄膜晶体管层设置于所述基板与所述阳极5之间。由于ITO作为纳米铟锡金属氧化物，具有很好的导电性和透光性，因此，本实施例中的阳极5的材质优选ITO，其他实施例中，所述阳极5的材质也可以选择其他材质。
如图1所示，所述显示面板还包括像素阻隔层6，所述像素阻隔层6设置于相邻两个所述阳极5之间的基板1上。所述像素阻隔层6主要是用于防止相邻发光单元之间产生光串扰现象。
如图1所示，发光层2设置于所述基板1的一侧的表面上。具体的，所述发光层2设置于所述阳极5远离所述基板1的一侧的表面上。所述发光层2的材质包括有机电致发光材料。
如图1、图2所示，所述发光层2包括相互间隔设置的第一发光单元21、第二发光单元22以及第三发光单元23。本实施例中，所述第一发光单元21为红色发光单元，所述第二发光单元22为绿色发光单元，所述第三发光单元23为蓝色发光单元。
如图1所示，所述显示面板100还包括阴极7。所述阴极7覆盖于所述发光层2远离所述基板1的一侧表面。由于ITO作为纳米铟锡金属氧化物，具有很好的导电性和透光性，因此，本实施例中的阴极7的材质优选ITO，其他实施例中，所述阴极7的材质也可以选择其他材质。
事实上，所述显示面板100还可以包括：空穴注入层（图未示）、电子阻挡层（图未示）、空穴阻挡层（图未示）、电子注入层（图未示）等结构，在此不再进行赘述。
如图1所示，封装层3设置于所述发光层2远离所述基板1的一侧的表面上。
如图3所示，所述封装层3可以包括第一无机层31、有机层32和第二无机层33。第一无机层31设置于所述发光层2远离所述基板1的一侧的表面上；有机层32设置于所述第一无机层31远离所述基板1的一侧的表面上；第二无机层33设置于所述有机层32远离所述基板1的一侧的表面上。其中第一无机层31和第二无机层33主要是起阻水氧作用，其中的有机层32主要是对封装层3受到的应力进行缓冲及释放，增加显示面板100的可弯折性能。
如图1所示，滤光层4设置于所述封装层3远离所述基板1的一侧的表面上。
如图1、图2所示，所述滤光层4包括：相互间隔设置的第一滤光单元41、第二滤光单元42以及平坦单元43。
如图1、图2所示，所述第一滤光单元41与所述第一发光单元21对应设置。具体的，所述第一发光单元21在所述基板1上的投影落入所述第一滤光单元41在所述基板1上的投影内。
如图4所示，由于所述第一发光单元21为红色发光单元，为了提高所述第一发光单元21发出光线的纯度，所述第一滤光单元41的滤光波长小于630nm，即所述第一滤光单元41对波长小于630nm的波段的光线进行吸收滤除。
其中，所述第一滤光单元41的材质为红色染料。所述红色染料包括：罗丹明类红色染料、蒽醌类聚合物树脂绿色染料、铁氧化物绿色染料中的一种或多种。
如图1、图2所示，所述第二滤光单元42与所述第二发光单元22对应设置。具体的，所述第二发光单元22在所述基板1上的投影落入所述第二滤光单元42在所述基板1上的投影内。
如图5所示，由于所述第二发光单元22为绿色发光单元，为了提高所述第二发光单元22发出光线的纯度，所述第二滤光单元42的滤光波长大于530nm，即所述第二滤光单元42对波长大于530nm的波段的光线进行吸收滤除。
其中，所述第二滤光单元42的材质为绿色染料。所述绿色染料包括：孔雀石绿绿色染料、酞菁绿绿色染料、偶氮类绿色染料中的一种或多种。
如图1、图2所示，所述平坦单元43与所述第三发光单元23对应设置。由于所述第三发光单元23为蓝色发光单元，且目前的蓝色发光单元发出的光线在光色方面已基本满足BT2020色域需求，因此本实施例不对所述第三发光单元23发出的光线进行调整，因此所述平坦单元43的材质可以选择透明透光材料，由此既可以使得所述滤光层4远离所述基板1的一侧的表面为平整表面，又可以避免显示面板的生产成本的增加。
如图1所示，所述滤光层4还包括黑色阻隔单元44。所述黑色阻隔单元设置于所述第一滤光单元41、所述第二滤光单元42以及所述平坦单元43之间的所述封装层3上。所述黑色阻隔单元44主要是用于防止相邻发光单元之间产生光串扰现象。
如图6、图7所示，本实施例通过在发光层2上设置滤光层4，利用滤光层4对发光层2发出的光线进行过滤调整，从而提高红色发光单元及绿色发光单元的发光纯度，由此将显示面板100的发光层2发出的光线调整至R (0.708，0.292)， G(0.170，0.797)，B(0.131，0.046)，从而有效的实现高BT2020色域覆盖，最终提升显示面板100的色彩显示能力。
