An electroluminescent element and an electroluminescent display device having realizing high luminance and high resolution are proposed. The electroluminescent element and an electroluminescent display device includes a first light emitting element provided with a first light emitter emitting light of a first color and a second light emitter emitting light of a second color different from the first color, the first light emitter and the second light emitter being disposed to be adjacent to each other, and a second light emitting element provided with a third light emitter disposed to overlap the first light emitter and the second light emitter and emitting light of a third color different from the first and second colors, wherein light of the first and second colors emitted from the first light emitting element is emitted through the second light emitting element.
