Abstract
A display panel includes a light-emitting substrate, an opposite substrate, and an intermediate layer assembly between the light-emitting substrate and the opposite substrate. The light-emitting substrate has a light-emitting surface configured to allow light to be emitted from, and the light emitted from the light-emitting surface is directed to the opposite substrate. The intermediate layer assembly includes a thin film encapsulation layer, a filler layer, and an overcoat that are sequentially stacked in a pointing direction vertically pointing from the light-emitting substrate to the opposite substrate. The thin film encapsulation layer includes at least two encapsulation sub-layers that are stacked in the pointing direction. In the pointing direction, refractive indexes of the encapsulation sub-layers gradually increase. A refractive index of the overcoat is higher than a refractive index of the filler layer.
