Patent ID: 8536057

Claim:
A method of manufacturing an organic light emitting device (OLED) by using a thin film deposition apparatus comprising: a deposition source; a first nozzle in which a plurality of first slits are formed in one direction, the first nozzle being disposed at one side of the deposition source; a second nozzle in which a plurality of second slits are formed in the one direction, the second nozzle being disposed to face the deposition source; a second nozzle frame combined with the second nozzle in order to support the second nozzle; a first barrier wall assembly comprising a plurality of first barrier walls disposed in the one direction so as to partition a space between the first nozzle and the second nozzle; and a second barrier wall assembly comprising a plurality of second barrier walls disposed in the one direction and a second barrier wall frame combined with the second barrier walls in order to support the second barrier walls, the second barrier wall assembly being disposed at one side of the first barrier wall assembly, the method comprising: preparing a substrate on which first electrodes are formed; forming an intermediate layer comprising an organic light emitting layer using the thin film deposition apparatus by vapor depositing a deposition material from the deposition source onto the substrate through the first slits and the second slits, so that the intermediate layer is connected to the first electrodes formed on the substrate; and forming second electrodes on the intermediate layer.
