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.

Abstract: The device includes a substrate, a green light emitting element on the substrate, and a green color film layer disposed on a light exit side of the green light emitting element correspondingly, a travel distance of the light emitted from the green light emitting element in the green color film layer remains substantially unchanged with a change of a light exit angle of the light. Thus, the present disclosure can prevent a color purity of a green light passing through the green color film layer from changing, thereby improving the color shift performance of a green light passing through the green color film layer, and improving the optical performance of the green light, and thus further improving the display effect of the device and the display panel.
