Abstract
A method for manufacturing a light emitting device includes providing a package having a recess in which a light emitting element is disposed. A translucent sealing material is provided in the recess to encapsulate the light emitting element. A film is provided on the translucent sealing material. The film includes a translucent base material and particles disposed in the translucent base material. The film has a contact surface to contact the translucent sealing material and an outer surface opposite to the contact surface. Abrasive is blasted onto the outer surface of the film to roughen the outer surface so as to expose at least one of the particles.
