Claim 4:
5. A deposition method comprising:
preparing a processing substrate in which a lower electrode, a rib including an aperture overlapping the lower electrode, and a partition including a lower portion arranged on the rib and an upper portion arranged on the lower portion and protruding from a side surface of the lower portion are formed above a substrate;
arranging the processing substrate on a first stage, setting an angle formed between an extension direction of a nozzle of a first deposition head and a normal of the first stage to a first angle, emitting vapor of a first material from the nozzle of the first deposition head, and depositing the first material on the processing substrate; and
arranging the processing substrate on which the first material is deposited, on a second stage, setting an angle formed between an extension direction of a nozzle of a second deposition head and a normal of the second stage to a second angle larger than the first angle, emitting vapor of a second material from the nozzle of the second deposition head, and depositing the second material on the processing substrate, wherein
a nozzle is surrounded by a sleeve having a first length in the first deposition head, in the depositing the first material.
