Abstract
A non-oil repellent photosensitive material layerand an oil repellent photosensitive material layerformed by coating on a substrateare exposed at the same time with light having a single wavelength (I-line) in accordance with bank regions and thereafter developed. In consequence, banksare formed having a double-layer structure which is comprised of bottom layer portionsof a non-oil repellent material and top layer portionsof an oil repellent material. This blocks organic EL materials supplied between the banksfrom moving beyond tops of the banksand prevents color mixing of the organic EL materials. Further, since the bottom layer portionsbetween 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.
