    Abstract: A display device featuring a touch detection and a fingerprint imaging functions is provided. A display device includes a light-emitting element and a light-receiving element. The light-emitting element includes a first pixel electrode, a light-emitting layer, and a common electrode, and the light-receiving element includes a second pixel electrode, an active layer, and the common electrode. The first pixel electrode and the second pixel electrode are provided on the same plane. The common electrode overlaps with the first pixel electrode with the light-emitting layer therebetween, and overlaps with the second pixel electrode with the active layer therebetween. A first conductive layer, a second conductive layer, and an insulating layer are provided above the common electrode. The insulating layer is provided above the first conductive layer, and the second conductive layer is provided above the insulating layer. The light-receiving element has a function of receiving light emitted from the light-emitting element.

    Abstract: A display apparatus in which a high voltage can be supplied to a display device is provided. The display apparatus includes a data generation circuit, a source driver circuit, and a pixel. The source driver circuit is electrically connected to the pixel through first and second wirings functioning as signal lines. The pixel includes a display device that is a liquid crystal device, a potential of one electrode of the display device can be a potential of the first wiring, and a potential of the other electrode of the display device can be a potential of the second wiring. The image data generation circuit has a function of generating digital image data including first and second data. In the case where image data corresponding to the digital image data is supplied to the pixel, one of the first and second wirings is made to have a potential corresponding to first data, and the other of the first and second wirings is made to have a potential corresponding to the first data. The potential of the first wiring and the potential of the second wiring are interchanged so that frame inversion driving or the like can be performed.

    Abstract: Efficiency of a charge pump circuit is increased. The charge pump circuit includes serially connected fundamental circuits each including a diode-connected transistor and a capacitor. At least one transistor is provided with a back gate, and the back gate is connected to any node in the charge pump circuit. For example, the charge pump circuit is of a step-up type; in which case, if the transistor is an n-channel transistor, a back gate of the transistor in the last stage is connected to an output node of the charge pump circuit. Back gates of the transistors in the other stages are connected to an input node of the charge pump circuit. In this way, the voltage holding capability of the fundamental circuit in the last stage is increased, and the conversion efficiency can be increased because an increase in the threshold of the transistors in the other stages is prevented.
