摘要： A display panel includes a substrate, a first electrode, a light-emitting layer, a second electrode, and one or more refractive film layers. The first electrode, the light-emitting layer, and the second electrode are sequentially disposed over the substrate. The substrate, the first electrode, and the one or more refractive film layers are configured to provide a stepwise graded refractive index along a transmission direction of lights emitted from the light-emitting layer and transmitted therethrough to thereby cause an improved outcoupling of the lights. The one or more refractive film layers may optionally include a first refractive film layer disposed on a surface of the substrate proximate to the first electrode, and may optionally include a second refractive film layer disposed on a surface of the substrate distal to the first electrode.
