Abstract: Disclosed are a display device and a method of manufacturing the display device. The display device includes a display panel on which a plurality of sub-pixels and lines connected to the sub-pixels and a driving circuit configured to drive the sub-pixels. The display panel further includes a plurality of protruded bank patterns disposed in the sub-pixels, and a light emitting element disposed in each of the bank patterns. The light emitting element includes a first electrode, a second electrode, a light emitting layer disposed between the first electrode and the second electrode, and a reflector that covers side surfaces of the light emitting layer and at least a portion of side surfaces of the first electrode. The reflector includes a first insulating layer, a second insulating layer, and a metal layer disposed between the first insulating layer and the second insulating layer.

Abstract: A method of manufacturing a graphene-tin oxide nanocomposite comprises dispersing graphene and tin oxide in an organic solvent to prepare a dispersion solution, drying the dispersion solution to obtain a powdery mixture, and irradiating the mixture with microwaves to obtain a graphene-tin oxide nanocomposite. Irradiation of graphene and tin oxide with microwaves results in the simplification of the manufacturing process of graphene-tin oxide nanocomposites and a decrease in manufacturing time and cost, and produce graphene-tin oxide nanocomposites at low temperatures. Further, the graphene-tin oxide nanocomposite with improved sensitivity to NO2 gas may be produced.
