Abstract: A display device includes a substrate provided with a pixel including an emission area and a laser area. The display device includes a lower mirror layer over the substrate. The display device includes a first light-emitting diode provided in the emission area over the lower mirror layer. The display device includes a second light-emitting diode provided in the laser area over the lower mirror layer. The display device includes an upper mirror layer over the second light-emitting diode.

Abstract: The present disclosure relates to an organic light emitting display device comprising a first substrate including a first pixel, the first pixel including first and second regions; a first electrode in the first region and on the first substrate, the first electrode having a first work function value; a second electrode in the second region and on the first substrate, the second electrode having a second work function value smaller than the first work function value; a first organic light emitting layer on the first electrode; a second organic light emitting layer on the second electrode; and a p-type charge generation layer in the first and second regions and on the first and second organic light emitting layers.

Abstract: A display device includes a substrate provided with a pixel including an emission area and a laser area and including a depressed portion corresponding to the laser area; a lower mirror layer in the depressed portion of the substrate; a first light-emitting diode provided in the emission area over the lower mirror layer; a second light-emitting diode provided in the laser area over the lower mirror layer; and an upper mirror layer over the second light-emitting diode.
