Abstract: The display device includes a light source that generates first light, a conversion layer that outputs a plurality of lights using the first light, and a color filter layer.
The conversion layer includes first to third conversion layers, and the color filter layer includes first to third color filters. The first conversion layer and the second conversion layer may include the same material.
The first conversion layer and the first color filter may convert the first dominant wavelength of the first light to output second light having a second frequency. The second dominant wavelength of the second light may be located at the first color vertex of the color reproduction rate standard.-
