1. An electroluminescent device comprising:

  • a first optical output part including a light-emitting layer that emits a light ray of a first color and a resonator structure that resonates the light ray of the first color emitted from the light-emitting layer;

    a second optical output part including a light-emitting layer that emits a light ray of a second color and a resonator structure that resonates the light ray of the second color emitted from the light-emitting layer; and

    a third optical output part including a light-emitting layer that emits a light ray of a third color and a resonator structure that resonates the light ray of the third color emitted from the light-emitting layer, wherein the first, second, and third colors are different from one another, and wherein, in each of the first to third optical output parts, when a peak value of a transmission spectrum of light transmitted through the resonator structure in a direction perpendicular to a main surface of the light-emitting layer is defined as a resonant peak wavelength, the resonant peak wavelength is on a longer wavelength side of an emission peak wavelength indicating a peak value of an emission spectrum of the light ray emitted by the light-emitting layer.
