Abstract:
1. A method for manufacturing a substrate by insulating an area except a part of a surface area of a base, which has electrical conductivity; the method comprising: supplying a first functional liquid to the surface of the base including the surface area, which has electrical conductivity; drying the first functional liquid to form a first protection layer having a circumferential partition wall on the base; supplying a second functional liquid only within an area surrounded by the partition wall such that the second functional liquid is held within the area surrounded by the partition wall; drying the second functional liquid to form a second protection layer and forming a protection film which includes the first protection layer and the second protection layer so as to cover over the surface area of the base, which has electrical conductivity; insulating the substrate; and removing the protection film.
