Abstract: A deposition apparatus includes: a vacuum chamber in which a deposition process is performable; connected to the vacuum chamber: vaporizers in which are vaporizable different deposition materials; and a mixing chamber in which the vaporized different deposition materials are mixable; and within the vacuum chamber: a substrate support on which is supportable a substrate on which the mixed vaporized different deposition materials are deposited in the deposition process; and a spray nozzle which is connected to the mixing chamber and from which the mixed vaporized different deposition materials are sprayable to the substrate in the deposition process. The spray nozzle includes nozzles arranged in a plurality of lines.

Abstract: An apparatus for manufacturing a display apparatus includes a deposition source, a nozzle head, a substrate fixer, and a deposition preventer. The deposition source is outside the chamber and vaporizes or sublimates a deposition material. The nozzle head is in the chamber, is connected to the at least one deposition source, and simultaneously sprays the deposition material onto an entire surface of a display substrate. The substrate fixer is connected to the chamber and moves linearly, with the display apparatus is mounted on the substrate fixer. The deposition preventer is in the chamber surrounding an edge portion of the nozzle head and an edge portion of the substrate fixer. The deposition preventer is heated during a deposition process.

Abstract: A linear evaporation source includes: a crucible accommodating an evaporation material; a heating unit enclosing the crucible and heating the crucible; and a nozzle unit above the crucible, the nozzle unit including a nozzle plate and at least one nozzle protruding from the nozzle plate. A length of the crucible is about 5 times to about 30 times greater than a width of the crucible. The crucible includes molybdenum (Mo) in an amount of about 95.0 percentage by weight (wt %) to about 99.99 wt % and lanthanum oxide (La2O3) in an amount of about 0.01 wt % to about 5 wt %, with respect to the total weight of the crucible.
