Patent ID: 8461058

Claim:
An organic layer deposition apparatus for forming an organic layer on a substrate, the apparatus comprising: an electrostatic chuck combined with the substrate so as to fixedly support the substrate, and comprising a receiving surface having a set curvature for receiving the substrate; a deposition source for discharging a deposition material toward the substrate; a deposition source nozzle unit disposed at a side of the deposition source and comprising a plurality of deposition source nozzles arranged in a first direction; and a patterning slit sheet disposed to face the deposition source nozzle unit, and having a plurality of patterning slits arranged in a second direction perpendicular to the first direction, wherein a cross section of the patterning slit sheet on a plane formed by lines extending in the second direction and a third direction is bent by a set degree, wherein the third direction is perpendicular to the first and second directions, wherein the deposition source, the deposition source nozzle unit, and the patterning slit sheet are separated from the substrate by a set distance so as to perform deposition while the substrate is moved in the first direction with respect to the deposition source, the deposition source nozzle unit, and the patterning slit sheet.
