WIPO Patent Application WO/2022/189884
Kind Code:
A1
Abstract:
Provided is a novel display apparatus that has excellent convenience, usefulness, or reliability. The present invention is a display apparatus that includes a first light-emitting device and a second light-emitting device, the second light-emitting device being adjacent to the first light-emitting device. The first light-emitting device comprises a first unit that emits light, a second unit that emits light, a first intermediate layer, and a first layer. The first intermediate layer is sandwiched between the second unit and the first unit; the first layer is sandwiched between the first intermediate layer and the first unit; and unpaired electrons can be observed in the first layer with a spin density of 1 × 1016 to 1 × 1018 spins/cm3 or less. The second light-emitting device comprises a third unit that emits light, a fourth unit that emits light, a second intermediate layer, and a second layer. The second intermediate layer is sandwiched between the fourth unit and the third unit; the second layer is sandwiched between the second intermediate layer and the third unit; there is a gap between the second intermediate layer and the first intermediate layer; and there is a gap between the second layer and the first layer.
