Abstract:
An organic layer deposition apparatus and a method of manufacturing an organic light emitting display apparatus by using the organic layer deposition apparatus. An organic layer deposition apparatus includes: a carrier including a chuck on which a substrate is mounted to form an organic layer; a scanning unit including a deposition unit for discharging a deposition raw material, and a patterning slit sheet having a plurality of patterning slits, the patterning slit sheet being smaller than the substrate in at least one of a first direction or a second direction perpendicular to the first direction; and a chamber accommodating the carrier and the scanning unit, the scanning unit being arranged to be spaced apart from the substrate and movable relative to the carrier.
