Abstract
An electronic device includes a sensor layer and a sensor driver. The sensor layer includes a first electrode, a first auxiliary electrode overlapped with the first electrode, a first loop electrode overlapped with the first electrode, a first loop trace line electrically connected to a first end portion of the first loop electrode, and a second loop trace line electrically connected to a second end portion of the first loop electrode that is spaced apart from the first end portion. The first loop electrode, the first loop trace line, and the second loop trace line are connected in a first closed loop.
