An electronic device includes a plurality of row electrodes including first and second row electrodes, which have first and second lengths, respectively, in a first direction, and a plurality of column electrodes including first and second column electrodes, which are adjacent to each other in the first direction and have third and fourth lengths, respectively, in a second direction. The device further includes a plurality of first lines connected to ends of the row electrodes, respectively, a plurality of second lines connected to ends of the column electrodes, respectively, and a plurality of third lines connected to opposite ends of the column electrodes, respectively. The second and fourth lengths are longer than the first and third lengths, respectively, and the first to third lines are spaced apart from each other when viewed in a plan view.
