Abstract
A display device includes a backlight having a main emitting peak in the region of 380-420 nm, a polarizer for selecting light having prescribed direction among the light emitted from a backlight source and an analyzer for receiving the selected light, a pair of electrodes provided between the polarizer and analyzer, optoelectronic material such as liquid crystal materials and PLZT provided between the electrodes, and a phosphor layer including phosphors which can be stimulated by exposure to the light from the backlight source. The display device has an increased viewing angle and improved luminance.
