Abstract:
1. A method for forming a thin film pattern by ejecting liquid drops which are made from a liquid which contains conductive particles to a predetermined thin film forming area on a substrate, the method comprising: a step of forming linear patterns on the substrate including: forming a central pattern by ejecting first liquid drops onto the substrate; forming a first side section pattern by ejecting second liquid drops onto the substrate, the first side section pattern being next to a first side of the central pattern; and forming a second side section pattern by ejecting third liquid drops onto the substrate, the second side section pattern being next to a second side of the central pattern, wherein the first side and second side are on opposite sides of the central pattern, and a volume of each second and third liquid drop which is ejected to form each of the first side pattern and the second side pattern is greater than a volume of each first liquid drop which is ejected to form the central pattern, and wherein: a first pitch exists between the first liquid drops which are ejected to form the central pattern; a second pitch exists between the second liquid drops which are ejected to form the first side pattern; a third pitch exists between the third liquid drops which are ejected to form the second side pattern; and each of the second and third pitches is narrower than the first pitch.
