Abstract: A display device includes a base substrate, a plurality of display elements, a first light control layer, and a second light control layer. The base substrate includes a pixel region and a peripheral region adjacent to the pixel region. The display elements are disposed on the base substrate, overlap the pixel region in a plan view, and are configured to generate a first light. The first light control layer is disposed on the display elements, and includes a transmission part configured to transmit the first light, a first light conversion part configured to convert the first light into a second light, and a second light conversion part configured to convert the first light into a third light. The second light control layer overlaps at least a portion of the first light conversion part in the plan view and is configured to convert the first light into the second light.
