1. A method of forming a film, said method comprising the steps of: a first step of forming a pattern film having linear portions on at least two sides thereof and projecting portions with a comb-teeth shape in a plan view at the linear portions; a second step of depositing a material for first and second functional films using said pattern film; and a third step of removing said material, which is deposited on said pattern film, with said pattern film so that said material deposited in a first region, which is not covered with said pattern film, is left as said first functional film and said material deposited in a second region, which is not covered with said pattern film, is left as said second functional film, wherein in said first step, a shape of said pattern film is formed such that a bottom surface of said first functional film has at least one first projecting portion corresponding to the projecting portion at one of the two sides and extending toward said second functional film and a bottom surface of said second functional film has at least one second projecting portion corresponding to the projecting portion at the other of the two sides and extending toward said first functional film.
