Abstract
An electrode substrate in which a lower electrode and an upper electrode are well positioned by way of an insulating film could not be formed by a printing method since positional displacement is caused. The cost was increased outstandingly when using photomasks for positioning. In the present invention, positional displacement does not occur even when using the printing method since the upper electrode and the lower electrode are positioned in self-alignment. Accordingly, a semiconductor device such as a flexible substrate using an organic semiconductor can be formed with low cost by using the printing method.
