## Abstract

A method for forming a thin film on a substrate includes 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 deposition material through a patterning slit sheet; and depositing the deposition material on the substrate, while moving the substrate and the patterning slit sheet relative to each other. The patterning slit sheet is spaced apart from the substrate by a distance. A blocking member is disposed between the substrate and the deposition source and is moved along with the substrate to be positioned to screen at least one portion of the substrate, and the patterning slit sheet is disposed opposite to and spaced apart from the deposition source nozzle unit, and includes a plurality of patterning slits arranged in the first direction.
