Abstract
In a TFT layer forming step, first, a semiconductor layer on a resin substrate is formed by performing a semiconductor layer forming step, and subsequently a gate insulating film is formed to cover the semiconductor layer by performing a gate insulating film forming step, and then a first metal layer is formed by performing a first metal film deposition step, a first photo step, and a first etching step, and a second metal layer is formed by performing a second metal film deposition step, a second photo step, and a second etching step, thereby forming a gate layer in which the first metal layer and the second metal layer are layered.
