Claim Text:
1. A method of manufacturing an organic light emitting display apparatus, the method comprising: disposing a substrate on an electrostatic chuck which comprises: a first plate; a first common wire disposed on the first plate and electrically connected to a plus (+) terminal of an electric power source; a plurality of first electrode patterns electrically connected to the first common wire between a first end and a second end of the first common wire, separated by a distance from each other, and extending from the first common wire; a second common wire disposed on the first plate and electrically connected to a minus (−) terminal of the electric power source; a plurality of second electrode patterns electrically connected to the second common wire, separated by a distance from each other, and extending from the second common wire; a first additional wire electrically connected to the first common wire at the first end and at the second end; and a second additional wire electrically connected to the second common wire; conveying the electrostatic chuck on which the substrate is disposed to pass through a plurality of chambers that are maintained in a vacuum state; and forming an organic layer on the substrate by using a thin film deposition assembly disposed in at least one of the chambers, by a movement of the electrostatic chuck or the thin film deposition assembly with respect to the other, wherein the thin film deposition assembly comprises a pattering slit sheet smaller than the substrate in a direction parallel to a side of the substrate on which the organic layer is formed.
