Patent ID: 8043550

Claim:
A manufacturing method of a display device, the method comprising: providing a base substrate; forming on the substrate a master layer provided with a predetermined pattern of openings exposing portions of the base substrate; treating the surfaces of the master layer and the base substrate exposed through the opening of the master layer with a reagent; and supplying a first material inside the openings to form a first material layer, the reagent surface treatment causing the difference of interface tensions between the master layer and the supplied first material to be larger than the interface tension between the supplied first material and the substrate, and a top surface of the first material layer is lower than a top surface of the master layer; fabricating a mold provided with a light shielding film by forming a moldable material layer on the base substrate and the master layer and then curing the moldable material layer and the light shielding material; arranging, pressurizing, and exposing the mold on an insulation substrate having a photosensitive film formed thereon after separating the mold from the master layer; and developing the photosensitive film after separating the mold from the insulation substrate, wherein the first material is a light shielding material.
