Abstract
A display device includes a substrate, a plurality of pixels arrayed on the substrate, an inorganic light-emitting element provided to each of the pixels, an anode electrode electrically coupled to the inorganic light-emitting element, a transistor provided on a first surface of the substrate, and coupling wiring that couples the anode electrode and the transistor. The anode electrode protrudes from an inside to an outside of the inorganic light-emitting element in planar view from a normal direction of the substrate.
