Abstract: A display device manufacturing apparatus includes a mask assembly, and a deposition module configured to supply a deposition material toward the mask assembly. The deposition module includes a deposition frame, a spraying portion, a heater, and a close contact portion. The deposition frame has an internal space. The spraying portion includes a crucible portion and a nozzle portion. The heater heats the nozzle portion and is configured to be switchable between a first state and a second state with a higher heating value than the first state. The close contact portion brings the crucible portion and the nozzle portion into close contact with each other, and the close contact portion includes a pressing surface spaced apart from the spraying portion in the first state and configured to press on the spraying portion in the second state.

Abstract: A metal plate used for manufacturing a deposition mask has a thickness of equal to or less than 30 μm. An average cross-sectional area of the crystals grains on a cross section of the metal plate is from 0.5 μm2 to 50 μm2. The average cross-sectional area of crystal grains is calculated by analyzing measurement results obtained by an EBSD method, the measuring results being analyzed by an area method under conditions where a portion with a difference in crystal orientation of 5 degrees or more is recognized as a crystal grain boundary.
