Abstract: A display device includes a display panel including a first pixel area and a second pixel area. The first pixel area includes a first pixel, a second pixel, and a third pixel, and the second pixel area includes a fourth pixel, a fifth pixel, and a sixth pixel. The first pixel and the second pixel are arranged to be adjacent to each other in a first direction, and the third pixel is arranged to be adjacent to the first pixel and the second pixel in a second direction that intersects the first direction. The third pixel and the fourth pixel emitting a same color are arranged to be adjacent to each other in the second direction, the fifth pixel is spaced apart from the first pixel in the second direction, and the sixth pixel is spaced apart from the second pixel in the second direction.

Abstract: A display device is disclosed that includes a base layer, a display element layer, a circuit element layer, a light control layer, and a quantum dot layer. The base layer includes first, second, and third light emitting regions and a non-light emitting region. The display element layer is disposed above the base layer and includes first, second, and third light emitting elements providing source light to the first, second, and third light emitting regions, respectively, toward the base layer. The circuit element layer is disposed between the base layer and the display element layer and includes first, second, and third pixel circuits connected to the first, second, and third light emitting elements, respectively, and overlapping the non-light emitting region. The light control layer is disposed between the display element layer and the circuit element layer and includes a color filter layer that includes first, second, and third color filters. The quantum dot layer is disposed on the color filter layer and includes quantum dots, and overlaps the first light emitting region and the first, second, and third pixel circuits.

Abstract: A display device includes a lower substrate, a pixel defining layer, a light emitting layer, an upper substrate, and a light blocking layer. The pixel defining layer is disposed on the lower substrate and includes a first opening and a second opening spaced apart from the first opening in a first direction. The light emitting layer is disposed in each of the first opening and the second opening. The upper substrate is disposed on the light emitting layer. The light blocking layer is disposed on the upper substrate and includes a third opening partially exposing the first opening and a fourth opening partially exposing the second opening. A first shape in which the first opening is exposed by the third opening and a second shape in which the second opening is exposed by the fourth opening are symmetrical to each other about a line of symmetry in a plan view.
