  • Liquid crystal display device
    Patent number: 4991939
    Abstract: A liquid crystal matrix display device is described which uses, as address devices, thin film transistors each comprising a gate, insulating film, semiconducting film, a source and a drain, and a picture element electrode formed in this order on an insulating substrate. The liquid crystal display device is characterized by source bus line-reinforcing thin film formed under the source bus line of each thin film transistor, on the same plane as the gate.
