Document Type and Number:
WIPO Patent Application WO/2023/085010
Kind Code:
A1
Abstract:
A light-emitting device according to one embodiment of the present disclosure comprises: a light source unit that has a light emission surface and emits first light from the light emission surface; and a wavelength conversion layer that is positioned on the light emission surface-side of the light source unit, has a first surface positioned facing the light emission surface and a second surface on the reverse side from the first surface, and includes a plurality of wavelength conversion materials and a plurality of scattering particles for converting the first light into second light in a different wavelength band, the absorption coefficient of the first light in the vicinity of the first surface being lower than the absorption coefficient of the first light in the vicinity of the second surface.
