Display apparatus and electronic device

Abstract

Provided is a novel display apparatus that is highly convenient, useful, or reliable. The display apparatus includes a blue-light-emitting device and a green-light-emitting device. The blue-light-emitting device includes a first unit, a second unit, and a first intermediate layer; and the first unit and the second unit each emit blue light. The first intermediate layer is interposed between the first unit and the second unit and supplies electrons to one of them and holes to the other; the second unit includes a first layer containing a first light-emitting material; and the first layer has its central plane a first distance away from a first reflective film. The green-light-emitting device includes a third unit, a fourth unit, and a second intermediate layer; and the third unit and the fourth unit each emit green light. The second intermediate layer is interposed between the third unit and the fourth unit and supplies electrons to one of them and holes to the other; the fourth unit includes a second layer containing a second light-emitting material; the second layer has its central plane a second distance away from a second reflective film; and the second distance is shorter than the first distance.
