Abstract: A display device includes: a light source unit having: a first light source to emit first light having a first peak wavelength; and a second light source to emit second light having a second peak wavelength, the second peak wavelength being shorter than the first peak wavelength; a wavelength conversion member to absorb the second light and convert the second light into first color light and second color light, each of the first and second color light having peak wavelengths different from the first and second peak wavelengths; and a display panel having a first pixel area to display the first color light, a second pixel area to display the second color light, and a third pixel area to display the first light, wherein the first peak wavelength and the second peak wavelength have a value of about 365 nm or more to about 500 nm or less.

Abstract: A display device includes a display member and a backlight unit, where the display member includes a base substrate, a cover layer that is on the base substrate, extends in a first direction, and includes a plurality of portions defining a first cavity and a second cavity that are spaced apart from the base substrate and adjacent to each other in the first direction, a first display element and a second display element that respectively correspond to the first cavity and the second cavity, a color conversion filter that is disposed on the cover layer, and includes a first filter which overlaps the first cavity and converts incident light into a first color light, and a second filter which overlaps the second cavity and converts incident light into a second color light, and an optical member which is disposed between the color conversion filter and the cover layer.
