Active matrix substrate, method of manufacturing the same, and display and image-capturing devices utilizing the same

A display device, comprising:

• an active matrix substrate;
• and
• an electro-optical medium driven by the active matrix substrate,
• the active matrix substrate including:
• electrode wires constituted by scanning electrodes and signal electrodes that are arranged in a lattice;
• an insulating film provided at least on the electrode wires so as to have openings in predetermined areas at least either on the scanning electrodes or on the signal electrodes;
• and a metal layer stacked on the electrodes in the openings.

An image-capturing device, comprising:

• an active matrix substrate;
• and
• a photoconductor of which electric charge is read by the active matrix substrate
• the active matrix substrate including:
• electrode wires constituted by scanning electrodes and signal electrodes that are arranged in a lattice;
• an insulating film provided at least on the electrode wires so as to have openings in predetermined areas at least either on the scanning electrodes or on the signal electrodes;
• and a metal layer stacked on the electrodes in the openings.

A method of manufacturing an active matrix substrate, comprising the steps of:

• (a) forming scanning electrodes and signal electrodes, for acting as electrode wires, arranged in a lattice on a substrate;
• (b) forming an insulating film at least on the electrode wires so as to have openings in predetermined areas at least either on the scanning electrodes or on the signal electrodes;
• and
• (c) forming a metal layer selectively in the openings on the electrodes.
