Area light emitting device, method for manufacturing area light emitting device, and optical device

摘要

An area light emitting device includes a transparent or translucent substrate and an area light emitting element arranged on the substrate. The substrate includes a first surface facing the area light emitting element and a second surface facing away from the area light emitting element. The area light emitting element emits light that enters the first surface and exits from the second surface. The second surface includes a recess for accommodating an optical member that changes the characteristics of the light emitted from the area light emitting element.
