ABSTRACT:
A non-oil repellent photosensitive material layer2and an oil repellent photosensitive material layer3formed by coating on a substrate1are exposed at the same time with light having a single wavelength (I-line) in accordance with bank regions and thereafter developed. In consequence, banks300are formed having a double-layer structure which is comprised of bottom layer portions31of a non-oil repellent material and top layer portions32of an oil repellent material. This blocks organic EL materials supplied between the banks300from moving beyond tops of the banks300and prevents color mixing of the organic EL materials. Further, since the bottom layer portions31between which organic layers are formed are made of the non-oil repellent material, the profiles of the organic layers will not change due to surface tension.
