Abstract

A display device includes a thin-film transistor layer disposed on a substrate, the thin-film transistor layer including a thin-film transistor, a light emitting element layer disposed on the thin-film transistor layer, the light emitting element layer including a pixel defining layer defining emission areas, and a pixel electrode disposed in each of the emission areas, a touch electrode disposed on the light emitting element layer, the touch electrode overlapping the pixel defining layer and sensing a touch, and a code pattern defined by a planar shape of the pixel defining layer that is distinguished from the pixel electrode and the touch electrode, the code pattern having position information.
