Method for manufacturing light emitting device
Provided is a method for manufacturing a light emitting device comprising a light emitting element and an optical part, the method comprising the steps of (i) forming a hydroxyl film on a bonding surface of each of the light emitting element and the optical part by an atomic layer deposition, and (ii) bonding the bonding surfaces of the light emitting element and the optical part with each other, each of the bonding surfaces having the hydroxyl film formed thereon, wherein a substep is repeated at least one time in the step (i), in which substep a first raw material gas and a second raw material gas are sequentially supplied onto the bonding surfaces of the light emitting element and the optical part, and wherein the bonding of the bonding surfaces in the step (ii) is performed without a heating treatment.
