Claim:
1. A method for manufacturing a light emitting device comprising the steps of: providing first substrates in a load chamber; sequentially transferring the first substrates via a transfer chamber from the load chamber to evaporation chambers, wherein the evaporation chambers are connected in series to each other; forming a layer comprising a light-emitting substance over each of the first substrates in the evaporation chambers; providing the first substrates in a substrate folder after forming the layer; forming an electrode over each of the first substrates in the substrate folder by batch processing in a first sputtering chamber; forming a protective layer over each of the first substrates in the substrate folder by batch processing in a second sputtering chamber after forming the electrode; and sequentially sealing each of the first substrates with a second substrate provided with an optical member in a sealing chamber, wherein the step of forming the layer is performed without an evaporation mask in the evaporation chambers, and wherein the first substrates in the substrate folder are arranged in parallel rows.
