1. An active-matrix liquid crystal display comprising:

  • a transparent upper substrate;

    a transparent lower substrate disposed opposite to the upper substrate;

    a liquid crystal filled and sealed in a space between the upper and the lower substrate;

    a plurality of parallel gate lines formed on the lower substrate;

    a plurality of parallel source lines formed on the lower substrate so as to extend perpendicularly to the gate lines;

    thin-film transistors formed at intersections of the gate lines and the source lines, respectively;

    pixel electrodes connected to the thin-film transistors, respectively; and

    storage capacitors connected to the pixel electrodes, respectively;

    wherein separate films are used as an insulating film included in the storage capacitors and a gate insulating film included in the thin-film transistors, respectively, and each of the storage capacitors has an upper electrode connected to the pixel electrode and a lower electrode disposed opposite to the upper electrode with the insulating film sandwiched between the upper and the lower electrode.
