Abstract

An electronic device includes a display layer displaying an image. A sensor layer is disposed on the display layer. The sensor layer includes a plurality of first sensing electrodes including a plurality of sensing patterns arranged along a first direction, and a plurality of bridge patterns electrically connecting adjacent sensing patterns of the plurality of sensing patterns. A plurality of second sensing electrodes includes a plurality of sensing portions arranged along a second direction crossing the first direction, and first connection portions extending in the second direction from the plurality of sensing portions. A pen-sensing electrode is disposed on a same layer as the plurality of bridge patterns. The pen-sensing electrode is disposed on a different layer than the plurality of sensing patterns and the plurality of second sensing electrodes.
