Abstract
A display apparatus with a novel structure is provided. The display apparatus includes a power supply line, a first transistor, a second transistor, a light-emitting device, and a light-receiving device. The light-emitting device includes a first electrode, a light-emitting layer, a first electron-transport layer, an electron-injection layer, and a second electrode that are stacked in this order. The light-receiving device comprises a third electrode, an active layer, a first hole-transport layer, the electron-injection layer, and the second electrode that are stacked in this order. The first electrode is electrically connected to one of a source and a drain of the first transistor. The second electrode is electrically connected to one of a source and a drain of the second transistor. The power supply line is electrically connected to the other of the source and the drain of the first transistor and the other of the source and the drain of the second transistor.
