Abstract:
A light-emitting device includes: at least one light-emitting element; a first light-transmissive member covering the light-emitting element; a second light-transmissive member covering the first light-transmissive member; and a light-diffusing member in the second light-transmissive member. The light-diffusing member includes hollow particles. The second light-transmissive member has a bottom surface having irregularities due to presence of the light-diffusing member.
