Claim:
1. A method for forming a thin film on a substrate, the method comprising: discharging a deposition material from a deposition source through a plurality of deposition source nozzles arranged in a first direction on a deposition source nozzle unit disposed at a side of the deposition source; passing the discharged deposition material through a patterning slit sheet; and depositing the passed deposition material on the substrate without any intervening elements between the patterning slit sheet and the substrate, while moving at least one of the substrate and the patterning slit sheet relative to the other, wherein the patterning slit sheet is spaced apart from the substrate by a distance, and a blocking member is disposed between the substrate and the deposition source and is positioned to screen at least one portion of the substrate, such that when at least one of the substrate and the patterning slit sheet is moved, the position of the blocking member with respect to the substrate is constantly maintained, and wherein the patterning slit sheet is disposed opposite to and spaced apart from the deposition source nozzle unit, and comprises a plurality of patterning slits arranged in the first direction, wherein the patterning slit sheet is between the substrate and the blocking member.
