The present invention relates to a display device. The display device comprises a color filter substrate comprising a color filter layer, an array substrate and a liquid crystal layer disposed between the color filter substrate and the array substrate, characterized in that the display device further comprises a reflective layer and a light excitation layer; the reflective layer is disposed on the side away from the liquid crystal layer of the array substrate, the light excitation layer and the color filter substrate are disposed on the same side of the liquid crystal layer; the light excitation layer emits stimulated light upon being excited by external light and the reflective layer is capable of reflecting the stimulated light to the color filter layer. The display device enhances the utilization to the external light and achieves a higher brightness and an improved color gamut.
