<P>PROBLEM TO BE SOLVED: To provide a luminance-adjusted layered light emission display device with high luminous efficiency. Ž<P>SOLUTION: The layered light emission display device is composed such that an optical distance L between a luminescent domain of an EL layer and a reflective surface of a reflecting electrode satisfy an interference conditional expression 1 for every luminescent color, an optical distance Lt between a reflective boundary face of a light extraction electrode side and the reflective surface of the reflecting electrode satisfy an interference conditional expression 2 or a conditional expression 3, and m' is ≥8. In the interference conditional expression 1, 2L/λ+δ/2π=m, in the interference conditional expression 2, Lt=(λ/2)×k, and in the interference conditional expression 3, 2Lt/λ+δ/2π=m'.
