Claim Text:
1. A deposition apparatus, comprising: a deposition source that receives a deposition material; and a plurality of spray nozzles arranged in a first direction at one side of the deposition source to spray the deposition material to a facing substrate, wherein: the deposition source includes a center area and outer areas, the outer areas being at respective ends of the center area with reference to the first direction, the spray nozzles include first spray nozzles arranged in each outer area and extending outwardly from the deposition source, the first spray nozzles each being inclined away from the center area, a surface forming an end of the first spray nozzles forming a first inclination angle with a substrate surface in the first direction, a center of the substrate in the first direction and a center of the deposition source in the first direction are aligned, the center area of the deposition source has a length in the first direction satisfying a condition as follows: wherein L1 is the length of the center area in the first direction, L2 is a deposition area length of the substrate in the first direction, T is a distance between the substrate and an end of the spray nozzles, and θ is the first inclination angle, second spray nozzles arranged at the center area extend from the deposition source such that a surface forming an end of the second spray nozzles has a second inclination angle in the first direction with respect to the substrate surface, and the second inclination angle is smaller than the first inclination angle.
