The present disclosure discloses a display panel which includes a substrate with varied reflectivity dependent upon different wavelengths; a plurality of light emitting diodes located on the substrate; and a light adjusting layer located on the substrate, wherein the light adjusting layer and the plurality of light emitting diodes are located on the same side of the substrate, the transmittance of material forming the light adjusting layer is varied dependent upon different wavelengths, and the transmittance change of the light adjusting layer at different wavelengths is inversely correlated with the change of the reflectivity of the substrate at the corresponding wavelengths.
