Abstract
A light emitting device includes a package, at least one light emitting element, a light-transmissive resin, and a light reflecting resin. The package has a recess which includes a bottom surface and an inner peripheral surface. The bottom surface includes a light emitting element mounting region and a groove. The groove has an inner peripheral edge and an outer peripheral edge on the bottom surface to define the groove between the inner peripheral edge and the outer peripheral edge. The at least one light emitting element is mounted on the light emitting element mounting region. The light-transmissive resin is provided in the recess to cover the at least one light emitting element and to be in contact with the groove. The light reflecting resin is provided between the inner peripheral surface of the recess and the light-transmissive resin to reach the outer peripheral edge of the groove.
