Abstract

A display panel includes: a plurality of light-emitting devices on a substrate, wherein each light-emitting device is configured to emit light of a preset color; a color conversion layer including a plurality of light exiting parts, wherein each light exiting part corresponds to one light-emitting device, and the light exiting part is configured to receive light emitted by the corresponding light-emitting device and emit light of a color same as or different from the preset color; and an optical layer between the color conversion layer and the plurality of light-emitting devices, wherein the optical layer is configured to transmit at least a portion of the light of the preset color and reflect the light of a color different from the preset color emitted by the color conversion layer; wherein second electrodes corresponding to at least two light exiting parts, which emits light of different colors, have different reflectivities.
