Organic layer including multiple reflective interfaces for light emitting illumination, and display apparatuses

摘要

A light-emitting apparatus including light-emitting devices emitting light of different single colors in a visible wavelength region, wherein each light-emitting device including: an organic layer between first and second electrodes and in which a first or second light-emitting layer emitting light of a different single color is included at a first or second position separated from each other in a direction from the first electrode to the second electrode; a first reflective interface on the side of the first electrode; and a second reflective interface and a third reflective interface which on the side of the second electrode in that order at mutually separated positions in a direction from the first electrode to the second electrode.

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.
