1. A liquid crystal display device comprising:

  • a first insulating substrate and a second insulating substrate disposed to be opposite to the first insulating substrate;

    a liquid crystal layer being interposed between the first insulating substrate and the second insulating substrate;

    charges-holding capacitance sections, each of which has an upper electrode, a dielectric film and a lower electrode, wherein said dielectric film is formed between said lower electrode and the upper electrode at each of said charges-holding capacitance sections, and said upper electrode contacts with said dielectric film through a contact hole provided by perforating a protective film formed over said dielectric film, and a semiconductor layer provided between said protective film and said dielectric film is selectively etched to be only around said contact hole.
