Abstract: An apparatus for manufacturing a display device includes: a stage on which a display substrate is arranged; an ink discharge module which discharges ink onto the display substrate; and an ink supply module which supplies ink to the ink discharge module. The ink supply module includes: a storage portion in which ink is stored; a first flow path connecting the storage portion to the ink discharge module in a way such that ink stored in the storage portion flows into the ink discharge module; and a second flow path connecting the storage portion to the ink discharge module in a way such that ink supplied to the ink discharge module flows into the storage portion.

Abstract: A method for forming a resin layer, the method including selectively applying an ultraviolet ray curable material that reacts to ultraviolet rays on a target substrate, selectively curing a preliminary resin layer by irradiating at least a portion of an entire area of the preliminary resin layer formed of the ultraviolet ray curable material with first ultraviolet rays whose shape and amount of light are adjusted, and completely curing the preliminary resin layer by irradiating second ultraviolet rays having a different amount of light from the first ultraviolet rays whose shape and amount of light are adjusted.
