1. A light-emitting device comprising:
a plurality of light sources that emit a first wavelength light disposed on a substrate;
a light reflection member configured to cover each of the plurality of light sources;
a plurality of wavelength conversion members configured to be disposed between the light sources and the light reflection member in a thickness direction and disposed in regions corresponding to the plurality of light sources in a plane, respectively;
wall portions between adjacent light sources of the plurality of light sources,
wherein one wall portion of the wall portions surrounds one light source of the light sources and is covered by an individual wavelength conversion member of the wavelength conversion members, the individual wavelength conversion member includes a quantum dot material that converts the first wavelength light to a second wavelength light or a third wavelength light and another wall portion of the wall portions surrounds another light source of the light sources and is covered by another individual wavelength conversion member, the another individual wavelength conversion member includes another quantum dot material that converts the first wavelength light to the second wavelength light or the third wavelength light.
