Claim:
1. A thin film deposition apparatus comprising: a deposition source comprising a crucible to contain a deposition material and a heater to heat and vaporize the deposition material; a nozzle unit disposed at a side of the deposition source extending in a first direction and comprising a plurality of nozzle slits to discharge the vaporized deposition material; a plurality of emission coefficient increasing units comprising a super-high speed rotary wing assembly, the emission coefficient increasing units being located within the crucible and facing the nozzle unit and configured to increase motion of the vaporized deposition material toward the nozzle unit; a patterning slit sheet opposite to the nozzle unit and comprising a plurality of patterning slits arranged along the first direction; and a barrier plate assembly between the nozzle unit and the patterning slit sheet, the barrier plate assembly comprising a plurality of barrier plates arranged along the first direction and partitioning a space between the nozzle unit and the patterning slit sheet into a plurality of sub-deposition spaces, wherein each of the plurality of super-high speed rotary wing assemblies is arranged to directly face a corresponding one of the plurality of nozzle slits arranged along the first direction.
