Abstract
A light emitting panela includes: a light emitting substrate including at least one light emitting region and a non-light-emitting region surrounding the light emitting region; and an encapsulation layer arranged on a light exiting side of the light emitting substrate, wherein the encapsulation layer includes a first film layer including a plurality of pillars separated from each other and a first medium arranged in gaps between the pillars; wherein a refractive index of the pillars is different from that of the first medium, and a volume ratio of the pillars to the first medium gradually increases or decreases along a first direction, so that an equivalent refractive index of the first film layer gradually decreases along the first direction, the first direction being a direction from a center of the light emitting region to an edge of the light emitting region.
