1. An electronic device comprising:
a base substrate;
a light emitting element disposed on the base substrate;
a thin film encapsulation layer disposed on the light emitting element;
an insulating layer disposed on the thin film encapsulation layer, the insulating layer including a first surface facing the thin film encapsulation layer and a second surface opposite to the first surface;
a first conductive layer disposed directly on the second surface of the insulating layer, the first conductive layer comprising a first touch electrode which comprises a first opening and a noise sensing electrode located in the first opening and spaced apart from the first electrode; and
a controller configured to receive a touch sensing signal from the first touch electrode and a noise sensing signal from the noise sensing electrode,
wherein the controller is configured to detect mutual capacitance between the first electrode and the noise sensing electrode, and
wherein each of the first touch electrode and the noise sensing electrode has a mesh structure.
