Abstract:
1. A method of manufacturing a matrix substrate, comprising steps of: preparing the matrix substrate; said matrix substrate comprising: a substrate with a principal surface; switching elements disposed on the principal surface of the substrate in a matrix form; pixel electrodes formed in correspondence with each of the switching elements; gate bus lines disposed on the principal surface of the substrate; and drain bus lines disposed on the principal surface of the substrate; wherein each switching element connects a drain bus line to a corresponding pixel electrode and a conduction state of each switching element is controlled by a signal applied to a corresponding gate bus line; forming an underlying film made of insulating material on each pixel electrode formed on the matrix substrate; forming a conductive film on the underlying film; forming a cover film made of insulating material on the conductive film; pattering the cover film; pattering the conductive film and the underlying film by using the patterned cover film as a mask; and heating the patterned cover film to fluidize the patterned cover film and cover the conductive film with the cover film.
