1. A method for manufacturing a thin film patterning substrate, comprising:
- providing a substrate;
forming banks on a surface of said substrate so as to form a plurality of areas partitioned by said banks, each of the banks having a width of a (μ
m) and a height of c (μ
m), and each one of the plurality of areas having a width of b (μ
m);
providing ink-jet droplets of a liquid material in said areas to form a thin film layer, said ink-jet droplets having a diameter of d (μ
m),wherein said banks and said ink-jet droplets satisfy a relationship d/2<
b<
5d.

Abstract
Display devices such as EL elements or LED elements, are formed from thin film elements having banks of prescribed height and a thin film layer formed by an ink jet method in areas to be coated that are partitioned by those banks. The banks may be formed of an organic material on a bank formation surface configured of an inorganic material, plasma treatment is performed under conditions that the induction gas is fluorine-based and that fluorine is present excessively, and the areas enclosed by the banks subjected to surface treatment are filled with the liquid thin film material to form the thin film layer or layers.
