Patent ID: 8900976

Claim:
A method of manufacturing an organic light-emitting display apparatus by using an organic layer deposition apparatus, the method comprising: attaching a substrate to a transfer unit in a loading unit; transporting the transfer unit into a chamber by using a first conveyer unit comprising a guide member having accommodation grooves to accommodate both sides of the transfer unit so as to guide a first direction movement of the transfer unit to which the substrate is attached, wherein the guide member comprises a first accommodation part, a second accommodation part, and a connection part, and passes through the chamber; forming an organic layer by depositing a deposition material discharged from an organic layer deposition assembly on the substrate while the substrate is moved relative to the organic layer deposition assembly in the chamber at a space from the substrate; separating the substrate on which the depositing has been completed from the transfer unit in an unloading unit; and transporting the transfer unit from which the substrate is separated to the loading unit by using a second conveyer unit that passes through the chamber, wherein the first accommodation part of the guide member is located closer to ground than the second accommodation part, and comprises a lower member, an upper member, and elastic members between the lower member and the upper member.
