Abstract: A display device includes a first substrate, a pixel defining layer on the first substrate, the pixel defining layer configured to define a light emission area, a first electrode in the light emission area, a light emitting layer on the first electrode, a second electrode on the light emitting layer, a second substrate which is opposite to the first substrate, and a reflecting member on a lower surface of the first substrate. The reflecting member may include a first reflecting unit on the lower surface of the first substrate, the first reflecting unit having an aperture at a position overlapping the light emission area, and a second reflecting unit on the first reflecting unit.

Abstract: An organic light-emitting display apparatus includes a display area including first and second pixels. A plurality of photo sensors is arranged in an outer area of the display area. The first pixel includes a first pixel electrode, an opposite electrode, and a first emission layer between the first pixel electrode and the opposite electrode. The first pixel electrode, the opposite electrode, and the first emission layer are arranged on a substrate. The second pixel includes a second pixel electrode, the opposite electrode having a reflectance less than a reflectance of the second pixel electrode, and a second emission layer between the second pixel electrode and the opposite electrode. The second pixel is closer to the plurality of photo sensors than the first pixel. The second pixel electrode includes a first portion in parallel with the substrate and a second portion having a slope with respect to the substrate.

Abstract: A display device includes a substrate and a reflection layer. The substrate includes a first emission region, a second emission region, a third emission region, and a non-emission region. The reflection layer overlaps the first emission region, the second emission region, and the non-emission region, and has an opening corresponding to the third emission region. The first emission region, the second emission region, and the third emission region emit different color light.
