A method is capable of easily forming a colored layer such as color filters or organic EL layers only in an active region on a transparent substrate for manufacturing a color liquid crystal display or an organic EL display unit. The method includes the steps of: forming a fine partition of a predetermined pattern using a light-blocking material in an active region on the surface of the transparent substrate, and depositing a light-blocking material into a non-active region; applying plural colors of coloring materials containing a colorant and a photosensitive resin into fine recesses separated by the fine partitions while relatively scanning a nozzle discharging a coloring material with respect to the transparent substrate; exposing the transparent substrate from back side to apply the plural colors and cure; and developing the surface side of the transparent substrate, dissolving the coloring materials applied into the non-active region and remaining not cured, and removing the materials.
