An electronic device includes a display panel including a display region and a non-display region and an input sensing member disposed on the display panel. The input sensing member includes first sensing electrodes arranged in n rows along a first direction. Second sensing electrodes cross the first sensing electrodes and are arranged in m columns along a second direction. N and m are each a natural number greater than or equal to 2. First signal lines are respectively connected to the first sensing electrodes. Second signal lines are respectively connected to the second sensing electrodes. A guard electrode is disposed along a first row first sensing electrode among the first sensing electrodes or a first column second sensing electrode among the second sensing electrodes. A guard line is electrically connected to the guard electrode. The guard electrode is electrically insulated from the first and second sensing electrodes.
