Abstract: The present disclosure relates to a display device including a display panel on which an image is displayed, a polarizer disposed on the display panel, a lower fluorescent filter disposed on the polarizer, and an upper fluorescent filter disposed on the lower fluorescent filter. The present disclosure may improve visibility when an image is displayed on the display device and light of a laser pointer in a visible light region is emitted thereto by absorbing the light using the upper and lower fluorescent filters, converting the light into light in a long wavelength band, which is a higher wavelength band than that of the absorbed light, and emitting the light in the long wavelength band.
