Abstract
According to one embodiment, a display device includes a display unit including electrodes, a touch sensor configured to supply drive signals to the electrodes and receive signals from the electrodes, and a switch circuit group including transistors connected between the touch sensor and the electrodes. The transistors include a first transistor connected to a first electrode via a line of a first length and a second transistor connected to a second electrode via a line of a second length longer than the first length. The channel width of the first transistor is smaller than a channel width of the second transistor.
