METHODS FOR MANUFACTURING WIRING SUBSTRATE, THIN FILM TRANSISTOR, DISPLAY DEVICE AND TELEVISION DEVICE

PROBLEM TO BE SOLVED: To provide a manufacturing technique for a display device manufactured by improving the utilization efficiency of materials and simplifying manufacturing processes, and to provide a technique for forming a pattern such as a wiring, constituting the display device, having a desired pattern with good controllability. SOLUTION: The subject method for manufacturing a wiring substrate includes the steps of: forming a first region having a material to be treated; modifying the surface of the material to be treated partly to form a second region having a boundary with respect to the first region; continuously discharging a composition containing a conductive material to a part of the first region across the boundary and the second region; solidifying the composition to form a conductive layer; and removing the conductive layer formed in the part of the first region across the boundary.
