One aspect of the present invention provides a light-emitting device, electronic device, or lighting device that consumes low power and has high reliability. A light emitting device, the light emitting device comprises: a first light emitting element; a second light emitting element; a third light emitting element; and a fourth light emitting element, wherein the first light emitting element, the second light emitting element, the third light emitting element and the fourth light emitting element The light-emitting elements all include a common EL layer between the anode and the cathode. The EL layer includes a first light-emitting layer and a second light-emitting layer. The first light-emitting layer contains a fluorescent light-emitting substance. The fluorescent light-emitting substance in the toluene solution of the fluorescent light-emitting substance The peak wavelength of the emission spectrum is from 440nm to 460nm, preferably from 440nm to 455nm, the second light-emitting layer contains a phosphorescent light-emitting substance, the first light-emitting element presents blue light, the second light-emitting element presents green light, and the third light-emitting element presents red light, And, the fourth light emitting element emits yellow light. |
