Each pixel includes a first electrode, first, second, and third light emitting layers on the first electrode, a second electrode on the first, second, and third light emitting layers, a fourth light emitting layer on the second electrode, and a third electrode on the fourth light emitting layer. The first, second, and third light emitting layers respectively emit first light, second light, and third light emitted in a first mode, and the fourth light emitting layer emits fourth light in a second mode.
