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.
