Abstract:
1. A thin-film transistor array device manufacturing method, comprising: preparing a substrate; forming a first gate electrode above the substrate; forming a second gate electrode above the substrate and adjacent to the first gate electrode; forming a gate insulating film on the first gate electrode and the second gate electrode; forming, on the gate insulating film, a noncrystalline semiconductor film at least in a first region above the first gate electrode and a second region above the second gate electrode; irradiating the noncrystalline semiconductor film formed in the first region and the second region with a laser beam having continuous convex light intensity distributions in both a short-axis direction and a long-axis direction; and forming a first source electrode and a first drain electrode above the first region, and a second source electrode and a second drain electrode above the second region, wherein, in the irradiating, the first region and the second region are scanned with the laser beam in one direction in one scanning, an inner region of the laser beam passing through the first region, an outer region of the laser beam passing through the second region, the outer region of the laser beam being outside of the inner region and continuous from the inner region, a light intensity of the outer region being lower than a light intensity of the inner region, wherein the first region and the second region are offset in a direction perpendicular to the one direction.
