Patent number: 10690975Abstract: Provided are an active-matrix substrate, a method for manufacturing the same, and a display device, which render it possible to inhibit electrostatic discharge from occurring during the process of manufacturing a display panel and suppress manufacturing cost. An IGZO film, which is positioned between a silicon oxide film included in a gate insulating film and an etch-stop layer, is annealed at 200 to 350° C. after a passivation film for protecting a TFT is formed. As a result, the passivation film is annealed, and the IGZO film is changed from a conductor to a semiconductor. Consequently, it is not only possible to suppress the occurrence of ESD, but also possible to eliminate the need to sever an electrostatic discharge prevention circuit from a display panel, resulting in a reduced cost of manufacturing a display device.Type: GrantFiled: March 24, 2017Date of Patent: June 23, 2020Assignee: SHARP KABUSHIKI KAISHAInventors: Tohru Okabe, Hirohiko Nishiki, Shinji Nakajima, Izumi Ishida, Shogo Murashige
