A display device having a narrow bezel region is provided. The display device includes a first layer and a second layer. The first layer includes a source driver and one part of a sensor, and the second layer includes a gate driver, a plurality of pixels, and the other part of the sensor. The plurality of pixels include a pixel in which a light-emitting element emits light and a pixel having a function of the gate driver. An opening portion where the one part of the sensor is formed and a first terminal connected to the source driver are provided on the top surface of the first layer, and a second terminal is provided on the opposite side of the surface where the pixels included in the second layer are arranged. The first terminal is bonded to the second terminal, so that they are electrically connected to each other and the sensor is formed. Since an output signal of the source driver is directly supplied through the first terminal to a wiring to which the plurality of pixels are connected, the source driver and the gate driver do not need to be provided in a peripheral region of a display region where the plurality of pixels are provided.
