摘要： A film having a plurality of lighting devices thereon is transferred between a film supplying roll and a film collecting roll, and an organic light emitting layer and a second electrode are formed on the film being transferred from a deposition unit. An aging unit is provided on a rear end of the deposition unit, and applies an aging voltage to the film transferred after the organic light emitting layer is deposited by the deposition unit, thereby aging the organic light emitting layer.
