Abstract:
1. A thin film transistor substrate comprising: on an insulating substrate, at least a gate electrode, a scanning line connected to the gate electrode, a gate insulating film, a semiconductor layer, a source electrode, a drain electrode, and a signal line connected to the drain electrode, wherein the gate electrode and/or the scanning line has a multilayer structure configured of a main wiring layer formed of a metal selected from Al, Ag and Cu or an alloy having a main component of Al, Ag and Cu, and of a nitrogen containing layer which is disposed below the main wiring layer and has nitrogen contained in the main wiring layer, wherein the main wiring layer and the nitrogen containing layer are formed such that respective side surfaces incline gently from the upper surface of the main wiring layer toward a lower layer.
