1. A light-emitting device comprising:
a first light-emitting element and a second light-emitting element, each configured to be independently driven;
a first lead on which the first light-emitting element is mounted;
a second lead on which the second light-emitting element is mounted;
a resin portion comprising a wall portion located between the first light-emitting element and the second light-emitting element, a first flat portion, and a second flat portion, the resin portion supporting the first lead and the second lead;
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;
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; and
a light reflecting member spaced apart from the first light-emitting element and the second light-emitting element and covering the wall portion; wherein;
a peak emission wavelength of the first wavelength converting member is longer than a peak emission wavelength of the second wavelength converting member;
in a plan view:
the wall portion is located between the first flat portion and the second flat portion,
the first flat portion is located closer to the first lead than the second lead and is flush with an upper surface of the first lead, and
the second flat portion is located closer to the second lead than the first lead and is flush with an upper surface of the second lead; and
the light reflecting member covers the first lead, the second lead, the first flat portion, and the second flat portion.
