Claim 1:
2. A display apparatus comprising:
a pixel, a first wiring, and a second wiring,
wherein the pixel comprises a first subpixel,
wherein the first subpixel comprises first to seventh transistors and a light-emitting/receiving element,
wherein one of a source and a drain of the first transistor is supplied with a first potential, and the other of the source and the drain of the first transistor is electrically connected to one of a source and a drain of the fourth transistor,
wherein one of a source and a drain of the third transistor is electrically connected to the first wiring, and the other of the source and the drain of the third transistor is electrically connected to a gate of the first transistor,
wherein the other of the source and the drain of the fourth transistor is electrically connected to one electrode of the light-emitting/receiving element and one of a source and a drain of the fifth transistor,
wherein the other of the source and the drain of the fifth transistor is electrically connected to one of a source and a drain of the sixth transistor and a gate of the second transistor,
wherein one of a source and a drain of the second transistor is electrically connected to one of a source and a drain of the seventh transistor,
wherein the other of the source and the drain of the seventh transistor is electrically connected to the second wiring,
wherein the other electrode of the light-emitting/receiving element is supplied with a second potential, and
wherein the light-emitting/receiving element is configured to emit light of a first color and to receive light of a second color.
