Abstract
A display device including a touch sensor and a driver for driving the touch sensor is provided. The display device has a touch panel function, an electrode of the touch sensor is electrically connected to a first driver circuit formed monolithically on a substrate where a pixel circuit is formed. A transistor including a metal oxide in a semiconductor layer can be used in the first driver circuit. The transistor included in the first driver circuit is easily downsized and can operate at high speed. Thus, the area occupied by the circuit can be reduced, which contributes to a narrower bezel.
