Document Type and Number:
WIPO Patent Application WO/2022/074499
Kind Code:
A1
Abstract:
Provided is a light-emitting apparatus having low power consumption. Provided is a light-emitting apparatus comprising a first light-emitting device and a first color conversion layer, wherein: the first light-emitting device comprises an anode, a cathode, and an EL layer positioned between the anode and the cathode; the EL layer is a material whose ordinary refractive index with respect to light having a 455-465 nm wavelength is 1.50 or greater and less than 1.75; the first color conversion layer includes a first substance that absorbs light and emits light; the first color conversion layer has an ordinary refractive index with respect to light having a 455-465 nm wavelength of 1.40-2.10; and the first color conversion layer is positioned on the optical path on which the light emitted by the first light-emitting device radiates out of the light-emitting apparatus.
