Abstract: A display device may include a light emitting element, a buffer layer, a gate insulation layer, and a switching element. A refractive index of the gate insulation layer may be equal to a refractive index of the buffer layer. The switching element may be electrically connected to the light emitting element and may include an active layer and a gate electrode. The active layer may be positioned between the buffer layer and the gate insulation layer and may directly contact at least one of the buffer layer and the gate insulation layer. The gate insulation layer may be positioned between the active layer and the gate electrode and may directly contact at least one of the active layer and the gate electrode.

Abstract: A method of forming an oxide semiconductor device may be provided. In the method, a substrate comprising a first major surface and a second major surface that faces away from the first major surface may be provided. An oxide semiconductor device may be formed over the first major surface to provide an intermediate device, and the semiconductor device may comprise an oxide active layer. The intermediate device may be subjected to ultraviolet (UV) light (e.g., ultraviolet ray irradiation process) for a first period, and subjected to heat (e.g., thermal treatment process) for a second period. The first and second periods may at least partly overlap.
