1. A method of producing a display panel board comprising:

  • a pixel electrode forming process of forming a pixel electrode formed from a transparent electrode film on a gate insulation film that covers a gate electrode;

    a semiconductor film forming process of forming a semiconductor film on the gate insulation film such that a part of the semiconductor film covers the pixel electrode, the semiconductor film forming process being performed after the pixel electrode forming process;

    an annealing process of processing the semiconductor film with annealing, the annealing process being performed after the semiconductor film forming process; and

    an etching process of processing the semiconductor film with etching such that a channel section overlapping the gate electrode is formed in a same layer as the pixel electrode, the etching process being performed after the annealing process.
