Abstract

A display device includes a light emitting element layer including a plurality of light emitting elements configured to output first color light, a color conversion layer on the light emitting element layer to receive the first color light, the color conversion layer being configured to convert the first color light so as to output at least two lights having colors different from each other, and a light collection layer between the light emitting element layer and the color conversion layer to collect the first color light, thereby providing the collected first color light to the color conversion layer. The light collection layer that collects the first color light may be disposed between the color conversion layer and the light emitting element layer to improve the light efficiency of the first color light outputted from the light emitting element layer, and also to prevent (or reduce) the colors from being mixed between the pixel areas, thereby improving the display quality.
