Abstract: An embodiment of a display device includes a substrate, a first light-emitting element, and a light control layer. The substrate includes a display area and a peripheral area adjacent to the display area, and the display area includes a light-emitting area and a light-blocking area. The first light-emitting element is disposed in the light-emitting area on the substrate and emits a first light having a first wavelength range. The light control layer is disposed on the first light-emitting element, and defines an opening exposing a portion of the light-emitting area. The light control layer includes a photochromic material such that in operation a second light having a second wavelength range different from the first wavelength range applied to the light control layer discolors the light control layer.

Abstract: A three-dimensional (3D) display device includes a display panel which operates in a first mode for displaying a first image or a second mode for displaying a second image and a liquid crystal lens panel disposed on the display panel, where the liquid crystal lens panel refracts the first image in a way such that the first image has a first viewing angle and refracts the second image in a way such that the second image has a second viewing angle greater than the first viewing angle. The liquid crystal lens panel includes an upper substrate, a first lens layer including a plurality of first lenses, a lower substrate, a second lens layer including a plurality of second lenses, and a liquid crystal layer. A first pitch of each of the plurality of first lenses is less than a second pitch of each of the plurality of second lenses.

Abstract: A display device includes a substrate, a first set of light emitting structures, a second set of light emitting structures, a diffraction layer, and a refraction pattern. The substrate includes a first region and a second region. The first set of light emitting structures overlaps the first region. The second set of light emitting structures overlaps the second region. The diffraction layer overlaps the first region without overlapping the second region. The refraction pattern overlaps the diffraction layer. The diffraction layer includes first-refractive-index members and second-refractive-index members that are alternately disposed. A refractive index of each of the first-refractive-index members is lower than a refractive index of each of the second-refractive-index members.
