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.
