An object is to provide a method of manufacturing a nitride semiconductor light emitting device having high light emission output and allowing decrease in forward voltage. A first subset of the data block is compared in parallel to the plurality of data patterns. The resilient membrane is mounted to the housing to cover and close the open end of the housing so as to set the chamber in an air-tight condition. The elastic member is connected between the frame and the movable member. The topcoat is then dried at an elevated temperature and an image is printed on the topcoat of the ink-jet recording media using a conventional ink-jet printer.
