Original Abstract Submitted

A novel display apparatus that is highly convenient, useful, or reliable is provided. The display apparatus includes a first light-emitting device including a first electrode, a first layer, a first unit, and a second electrode and a second light-emitting device including a third electrode, a second layer, a second unit, and a fourth electrode. The first unit is between the first electrode and the second electrode and includes a first light-emitting material. The first layer is between the first unit and the first electrode and is in contact with the first electrode. The third electrode is adjacent to the first electrode. A first gap is between the third electrode and the first electrode. The second unit is between the third electrode and the fourth electrode and includes a second light-emitting material. The second layer is between the second unit and the third electrode and is in contact with the third electrode. The first layer and the second layer use a material having a first spin density and a material having a second spin density higher than the first spin density, respectively, each observed with an electron spin resonance (ESR) spectrometer when the material is in a film state.
