Abstract:
A light-emitting device includes: a first light-emitting element and a second light-emitting element, each configured to be independently driven; a wall portion located between the first light-emitting element and the second light-emitting element; a first light-transmissive member separated from the second light-emitting element by the wall portion and covering at least a portion of lateral surfaces of the first light-emitting element, wherein the first light-transmissive member contains a first wavelength converting member; and a second light-transmissive member covering the first light-emitting element, the second light-emitting element, and the first light-transmissive member in a plan view, wherein the second light-transmissive member contains a second wavelength converting member. A peak emission wavelength of the first wavelength converting member is longer than a peak emission wavelength of the second wavelength converting member.
