Abstract:
1. A thin film deposition apparatus that forms a thin film on a substrate, the apparatus comprising: a deposition source that discharges a deposition material; a deposition source nozzle unit that is disposed at a side of the deposition source and comprises a plurality of deposition source nozzles arranged in a first direction; a patterning slit sheet that 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; a barrier plate assembly that is disposed between the deposition source nozzle unit and the patterning slit sheet, and comprises a plurality of barrier plates in the first direction that partition a space between the deposition source nozzle unit and the patterning slit sheet into a plurality of sub-deposition spaces; and a blocking member that is disposed between the substrate and the deposition source and that is spaced apart from the substrate, wherein the thin film deposition apparatus is spaced apart from the substrate by a predetermined distance, the substrate and the thin film deposition apparatus move relative to each other, and when the substrate and the thin film deposition apparatus are moved relative to each other, the blocking member is moved along with the substrate to be positioned to screen at least one portion of the substrate, and wherein the patterning slit sheet is between the substrate and the blocking member.
