1. An electronic device comprising:
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 including:
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,
wherein the first branch portion includes a plurality of first branches and a plurality of second branches,
wherein each of the first branches extends downward from one end of the first trunk portion in the second direction, and each of the second branches extends upward from an other end of the first trunk portion in the second direction, and a number of the first branches is equal to a number of the second branches,
wherein the input sensor includes an active area in which the first sensing electrode is disposed, the active area of the input sensor includes a plurality of unit areas each having a first pitch, and at least one of the first branches and at least one of the second branches cross over each of the unit areas,
wherein the first branches and the second branches include a first portion that is adjacent to the first trunk portion and a second portion that is not adjacent to the first trunk portion, and the second portion has a width greater than a width of the first portion,
wherein the input sensor includes an active area in which the first sensing electrode is disposed and a peripheral area defined adjacent to the active area, and the active area includes a first unit area and a second unit area adjacent to the first unit area, and
wherein the first trunk portion and at least some portions of the first portion are disposed in the first unit area, and an entirety of the second portion is disposed in the second unit area.
