Abstract:
1. A display device comprising: a substrate; a scanning signal line formed over the substrate; an insulating film formed over the substrate and the scanning signal line; an image signal line; a pixel electrode; and a thin film transistor applied with a gate signal from the scanning signal line and comprising a semiconductor film formed over the insulating film, a drain electrode electrically connected to the image signal line, and a source electrode electrically connected to the pixel electrode, wherein the scanning signal line comprises a first metal film and a second metal film formed over the first metal film, with respect to a sectional view, the second metal film having a top surface with a width that is smaller than a width of a bottom surface of the first metal film at least in a crossover portion of the scanning signal line and the image signal line.
