Patent ID: 6894734

Claim:
A liquid-crystal display device comprising: a plurality of address wires formed on an insulating substrate; a gate insulating film formed on said address wires and on said insulating substrate; a plurality of data wires, said data wires crossing said address wires; an upper layer insulating film formed on said data wires and on said gate insulating film, said upper layer insulating film having a smaller thickness and higher dielectric constant than the gate insulating film; and a picture element area comprising: a transparent electrode, comprising a transparent conductive film, formed on said upper layer insulating film and surrounded by said address wires and said data wires; a thin-film transistor section for selectively connecting said data wires with said transparent electrode by a gate connected to said address wires; and a capacitor section comprising: a first electrode formed on said gate insulating film and comprising the same conductive film as in said data wires, and having an innermost portion formed over said address wires; a second electrode on said upper layer insulating film and comprising the same transparent conductive film as in said transparent electrode; and at least a portion of said upper layer insulating film formed between said first electrode and said second electrode.
