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 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.

Abstract: A method of manufacturing a meta-optical element includes propagating light with random phase distribution toward a light collecting surface, obtaining a simulation intensity of the light at the light collecting surface through simulation, generating an error function based on an error data which is a difference between the simulation intensity of the light and an ideal intensity of the light, obtaining an optimal phase distribution of the light which outputs a minimum function value of the error function by applying a gradient descent, and forming a meta-optical element that implements the optimal phase distribution.
