Claim:
A method of forming a film pattern by disposing functional liquid on a substrate, comprising: forming a plurality of banks on the substrate, adjacent banks beings separated by a trench having a plurality of first portions including a first width that are each connected by a plurality of second portions having a second width, the second width being greater than the first width and a transition region between the first portions and the second portions being hexagonal in shape when viewed in plan; disposing the functional liquid in the trench partitioned by the banks; and drying the functional liquid disposed on the substrate, wherein the forming of the banks includes: forming a thin film on the substrate, the thin film being made of a material for forming the banks; after forming the thin film on the substrate, performing lyophobic treatment on a surface of the thin film; and after performing the lyophobic treatment on a surface of the thin film, patterning the thin film into the shapes of the banks.
