Abstract
A photo-luminescent display device includes: a backlight to output a backlight; a first substrate and a second substrate facing each other; a pixel electrode disposed on the first substrate; a light amount control layer disposed in a space between the first substrate and the second substrate to control a transmittance of the backlight; a first light conversion portion disposed on the second substrate to convert a wavelength of the backlight; a light diffusion portion disposed adjacent to the first light conversion portion to diffuse the backlight; and a barrier surrounding the first light conversion portion. The light diffusion portion and the barrier include a unitary structure.
