Abstract
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 ran…
