Abstract:
1. A deposition apparatus that forms a thin film in a predetermined pattern on a substrate, comprising: a deposition mask having a plurality of openings having a stripe pattern; a deposition source that has an emission port on a side of the deposition mask, and that emits, through the emission port, deposition particles forming the thin film; and a first correction plate and a second correction plate placed between the deposition mask and the deposition source so that each of the first and second correction plates is separated from the deposition mask, the deposition source, and the other correction plate by a predetermined interval, the first correction plate being located on a side of the deposition source, and the second correction plate being located on the side of the deposition mask, a mask unit including the deposition mask, the deposition source, and the first and second correction plates, wherein a relative positional relation among the deposition mask, the deposition source, and the first and second correction plates being fixable; and a first actuator that electrically operates to relatively move at least one of the mask unit and the substrate along a predetermined scanning direction with a constant gap being provided between the substrate and the deposition mask, wherein each of the first and second correction plates has a plurality of blade plates each having a rectangular shape, the plurality of blade plates are arranged in rows substantially parallel to the deposition mask, and a frame that supports both longitudinal ends of the plurality of blade plates, each of the first and second correction plates is placed so that a longitudinal direction of the blade plates matches the scanning direction, each of the blade plates is arranged in the frame so as to be laterally tilted with respect to the deposition mask with a gap between adjoining ones of the plurality of blade plates, and the plurality of blade plates of the first correction plate are arranged so that one of the plurality of blade plates is not overlapped with another adjoining one of the blade plates as viewed in a direction orthogonal to the deposition mask, the plurality of blade plates of the second correction plate are arranged so that one of the plurality of blade plates is not overlapped with another adjoining one of the blade plates as viewed in the direction orthogonal to the deposition mask.
