PROBLEM TO BE SOLVED: To solve the problems of an organic EL element emitting blue light in that a life span is short and luminance characteristic is low, in comparison with a green or red light element, particularly, in a case of applying the EL element to a light-emitting device capable of modulating luminous color, attenuation is remarkable and furthermore characteristics are degraded.SOLUTION: The attenuation of light is suppressed by disposing a dielectric mirror having wavelength selectivity among a plurality of organic EL elements, and particularly, by causing the blue light of the organic EL elements not to pass through electrodes having light transmissivity as much as possible. Thereby, it is possible to provide a light-emitting device which has high luminance and long life and can modulate luminous color. Further, in this light-emitting device, color tone can be maintained at a constant over a long period by independently controlling an electric voltage applied to each of the organic EL elements which are individually degraded.
