ABSTRACT:
An organic electroluminescent color light-emitting apparatus including, on a supporting substrate (100), a first pixel (10) comprising a first organic electroluminescent device emitting light having an emission peak wavelength of λ1; and a second pixel (20) comprising a second organic electroluminescent device emitting light having an emission peak wavelength of λ2; the emission peak wavelength λ2being longer than λ1; the first and second organic electroluminescent devices each being a device in which a light-reflective electrode (11), (12), an organic luminescent medium layer and a semitransparent electrode are stacked in this order in the light-outcoupling direction; and m1and m2defined by the following formula (1) satisfying the relationship of m2+1.3>m1>m2+0.7 (m1and/or m2is an approximate integer of 0 or more).mx=2⁢Lxλx+Φx2⁢π(1)
