Abstract
A display device includes: a base substrate; a self-light emitting element on the base substrate; a thin film encapsulation layer on the self-light emitting element; a first sensing electrode on the thin film encapsulation layer and including an opening; a second sensing electrode on the thin film encapsulation layer and spaced apart from the first sensing electrode; a conductive pattern in the opening and spaced apart from the first sensing electrode; and a sensor controller configured to detect a change of a mutual capacitance between the first sensing electrode and the second sensing electrode in a first mode and configured to detect a change of a mutual capacitance between the conductive pattern and the first sensing electrode in a second mode different from the first mode.
