Abstract:
1. A light-emitting apparatus comprising a plurality of light-emitting devices configured to emit light, wherein: each light-emitting device includes an organic layer between a first electrode and a second electrode, and the organic layer includes: a first light-emitting layer configured to emit light, (ii) a second light-emitting layer configured to emit light in a different wavelength than the first light-emitting layer, (iii) a first reflective interface facing the second electrode and at a position within the organic layer such that the intensity of light reflected from the first and second light emitting layers is greater than the intensity of the light emitted from the first light and second light emitting layers, (iv) a second reflective interface facing the first electrode and at a position within the organic layer such that the wavelength range of the light reflected from the first and second light emitting layers is broader than the wavelength of light emitted from the first and second light emitting layers, and (v) a third reflective interface facing the first electrode and at a position within the organic layer such that the wavelength range of the light reflected from the first and second light emitting layers is broader than the wavelength of light emitted from the first and second light emitting layers.
