Abstract:
1. An organic electroluminescent color light-emitting apparatus comprising, on a supporting substrate, a first pixel comprising a first organic electroluminescent device emitting light having an emission peak wavelength of λ a second pixel comprising a second organic electroluminescent device emitting light having an emission peak wavelength of λ the emission peak wavelength λ the first and second organic electroluminescent devices each being a device in which a light-reflective electrode, an organic luminescent medium layer and a semitransparent electrode are stacked in this order in the light-outcoupling direction; and m wherein Lx is an optical distance between a light-reflective electrode and a semitransparent electrode for light having a wavelength of λx; Φ x is the total value of phase shifts which occur when light having a wavelength of λ x is reflected at the surface of the light-reflective electrode and at the surface of the semitransparent electrode; and x is 1 or 2, x=1 shows a value of the first organic electroluminescent device and x=2 shows a value of the second organic electroluminescent device.
