Abstract: An electronic apparatus includes an electronic panel including a plurality of sensing groups spaced apart from each other, and an electronic module overlapping with the electronic panel in a plan view. Each of the sensing groups includes a first sensing electrode extending in a second direction, and second sensing electrodes spaced apart from each other in the second direction, located on the same layer as the first sensing electrode, and face the first sensing electrode in a first direction. An opening overlapping with the electronic module and penetrating a first sensing group of the sensing groups is defined in the electronic panel, and at least one selected from the first sensing electrode and the second sensing electrodes of the first sensing group extends along an edge of the opening.
