A light emitting device contains organic EL elements of different colors and outputs light emitted from the organic EL elements, in which, when outputting white light, the organic EL element, in which the luminance when light is emitted at a current density at which a luminous efficiency reaches a maximum is lower than that of the organic EL elements of the other colors, among the organic EL elements of different colors emits light with a current having a current density higher than the current density at which the luminous efficiency reaches the maximum and a highest duty among the organic EL elements of different colors, and the organic EL elements of the remaining colors emit light with a current having the current density at which the luminous efficiency reaches the maximum and at a duty lower than the duty.
