Abstract: An electronic device includes a display panel and an input sensor disposed on the display panel and having a first sensing electrode extending in a first direction. The first sensing electrode includes a first trunk portion extending in the first direction and a first branch portion extending from the first trunk portion in a second direction crossing the first direction. The first branch portion includes a plurality of first branches and a plurality of second branches. The first branches extend in a direction opposite to a direction in which the second branches extend in the second direction, and the number of the first branches is equal to the number of the second branches.
