    Abstract: The resolution of a display apparatus having alight detection function is increased. The display apparatus includes a light-emitting device and a light-emitting and light-receiving device. The light-emitting device includes a first pixel electrode, a first light-emitting layer, and a common electrode; the light-emitting and light-receiving device includes a second pixel electrode, a second light-emitting layer, an active layer, and the common electrode; the active layer includes an organic compound; the first light-emitting layer is positioned between the first pixel electrode and the common electrode; the second light-emitting layer and the active layer are each positioned between the second pixel electrode and the common electrode; the light-emitting device has a function of emitting light of a first color; and the light-emitting and light-receiving device has a function of emitting light of a second color and a function of receiving light of the first color. The light-emitting and light-receiving device functions as both a light-emitting device and a light-receiving device, whereby a pixel can have a light-receiving function without an increase in the number of subpixels included in the pixel. Furthermore, the pixel can be provided with a light-receiving function without a reduction in the resolution of the display apparatus or a reduction in the aperture ratio of each subpixel.

    Abstract: A novel display panel that is highly convenient or reliable is provided. The display panel includes a pixel comprising a pixel circuit and a display element, and the display element is electrically connected to the pixel circuit. The pixel circuit is supplied with a selection signal, an image signal, and a pulse width control signal, supplies an output potential, and determines, on the basis of the pulse width control signal, a period during which the output potential is supplied. The pixel circuit includes a first switch and a first transistor. The first switch supplies the image signal on the basis of the selection signal and determines the output potential on the basis of the image signal. The first transistor includes a first and second electrode, and a first gate electrode. The output potential is output from the first electrode, and the first gate electrode is supplied with the image signal.

    Abstract: A display device includes a liquid crystal element, a transistor, a scan line, and a signal line. The liquid crystal element includes a pixel electrode, a liquid crystal layer, and a common electrode. The scan line and the signal line are each electrically connected to the transistor. The scan line and the signal line each include a metal layer. The transistor is electrically connected to the pixel electrode. A semiconductor layer of the transistor includes a stack of a first metal oxide layer and a second metal oxide layer. The first metal oxide layer includes a region with lower crystallinity than the second metal oxide layer. The transistor includes a first region connected to the pixel electrode. The pixel electrode, the common electrode, and the first region are each configured to transmit visible light. Visible light passes through the first region and the liquid crystal element and exits from the display device.
