PROBLEM TO BE SOLVED: To compensate for the change of chromaticity and intensity of display due to shifting of a resonance peak wavelength to short wavelength side, which is caused since the optical resonator length becomes shorter as the angle of observation direction becomes deeper from a front direction toward an oblique direction of an insulating substrate face. SOLUTION: Other resonance peaks B', B" are generated additionally in a long wavelength part of, for example, blue spectrum A in an oblique direction (as represented by 30°, 45°) from the front direction (0°) of the insulating substrate face, and the long wavelength-side emission color is reinforced by shifting in the spectrum region 301 of the light-emission spectrum.
