Display device
The present disclosure relates to a display device in the field of display. The display device comprises a plurality of sub-pixel areas, each of which corresponds to one color, wherein the display device comprises a reflecting interface, a photon conversion layer, and a light filter layer arranged sequentially along a display light emergent direction; in the sub-pixel area corresponding to a target color: the light filter layer is structured to transmit light within a first wavelength range in the display light emergent direction and reflect the light within a second wavelength range, wherein the first wavelength range refers to the wavelength range corresponding to the target color, and the second wavelength range includes a visible light waveband excluding the first wavelength range; the reflecting interface is structured to reflect the light from the light filter layer; and the photon conversion layer is structured to convert the transmitted light within a third wavelength range to the light within the first wavelength range, the third wavelength range is a preset wavelength range beyond the first wavelength range and the second wavelength range includes the third wavelength range. The present disclosure can improve the color conversion efficiency of the display device.
