Abstract
A light-emitting device includes a substrate, a light-emitting element, a wavelength conversion layer, a light adjustment member, a light-transmissive member, and a covering member. The light-emitting element includes first and second light-emitting portions. The wavelength conversion layer contains a first phosphor that performs wavelength conversion of first light emitted from the first light-emitting portion and second light emitted from the second light-emitting portion into third light. The light adjustment member is disposed partially over the wavelength conversion layer and overlaps one of the first light-emitting portion and the second light-emitting portion in plan view. The light-transmissive member is disposed over the wavelength conversion layer and the light adjustment member. The covering member covers a side surface of the light-emitting element, a side surface of the wavelength conversion layer, a side surface of the light adjustment member, and a side surface of the light-transmissive member.
