1. An organic light-emitting device comprising, on an insulating layer, a first lower electrode, an upper electrode, and an organic compound layer disposed between the first lower electrode and the upper electrode,
wherein the organic compound layer includes a first light-emitting layer, a second light-emitting layer disposed between the first light-emitting layer and the upper electrode, and a first organic compound layer disposed between the first light-emitting layer and the second light-emitting layer,
the first organic compound layer includes a second organic compound layer containing an alkali metal, and a third organic compound layer disposed between the second organic compound layer and the upper electrode and containing a compound having a lowest unoccupied molecular orbital level energy of −5.0 eV or less, and
an orthogonal projection of an entirety of the first organic compound layer onto the insulating layer is smaller than an orthogonal projection of an entirety of the first light-emitting layer onto the insulating layer.
