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.
