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 display device includes a display unit, an upper electrode layer, a lower electrode layer and an electrochromic layer. The display unit includes a plurality of light emitting diodes disposed in a light emitting area. The upper electrode layer is disposed on the display unit, and includes a plurality of first electrode patterns and a plurality of second electrode patterns. The first electrode patterns are arranged in a first direction, and are electrically connected each other. The second electrode patterns are arranged in a second direction intersecting the first direction and are electrically connected each other. The lower electrode layer is disposed between the upper electrode layer and the display unit. The electrochromic layer is disposed between the upper electrode layer and the lower electrode layer, and includes an electrochromic pattern.
