Abstract:
1. A light-emitting element comprising: an anode having a reflective electrode and a transparent electrode; a cathode; and an organic layer provided between the anode and the cathode, wherein the light-emitting element has a resonance spectrum having a primary resonance peak whose central wavelength is positioned on a long wavelength side with respect to a wavelength at which a relative luminosity takes a maximum value and a secondary resonance peak whose central wavelength is positioned on a short wavelength side with respect to the wavelength at which the relative luminosity takes the maximum value, and the light-emitting element has an emission output spectrum having a primary peak whose central wavelength positioned on a long wavelength side with respect to the wavelength at which the relative luminosity takes the maximum value and a secondary peak whose central wavelength is positioned on a short wavelength side with respect to the wavelength at which the relative luminosity takes the maximum value and which has an emission intensity smaller than that of the primary peak.
