Abstract:
1. A light-emitting apparatus comprising a plurality of light-emitting devices emitting light of different single colors in a visible wavelength region, wherein: each of the plurality of light-emitting devices includes (a) an organic layer between a first electrode and a second electrode and in which a first light-emitting layer or a second light-emitting layer emitting light of different single colors is included at a first position or a second position separated from each other in a direction from the first electrode to the second electrode, light being emitted from the light emitting device via the second electrode, (b) a first reflective interface between the first electrode and the organic layer so as to reflect light emitted from the first light-emitting layer or the second light-emitting layer toward the second electrode, and (c) a second reflective interface and a third reflective interface which are provided between the second electrode and the organic layer at mutually separated positions in that order in a direction from the first electrode to the second electrode, each of the second and third reflective interfaces reflecting light toward the first electrode; 2L 2L 2L 2L 2L 2L λ λ (i) λ (ii) λ
