摘要： A liquid crystal display device includes first and second substrate and a liquid crystal layer sealed between the substrates. A plurality of pixel elements are formed in a matrix pattern on the first substrate, and a plurality of driving nonlinear resistance elements are formed on the first substrate and electrically connected to the pixel electrodes, respectively. A plurality of parallel wiring electrodes are formed on the first substrate, respectively extending in parallel to the columns of the pixel electrodes, and electrically connected to the respective nonlinear resistance elements on the respective columns of the pixel electrodes. Each wiring electrode is divided at a dividing portion and has a pair of divided ends. Protecting nonlinear resistance elements are respectively formed on the divided ends of each wiring electrode so as to reduce potential difference between the divided ends when static electricity is generated at the dividing portions.

摘要： A thin film transistor of this invention has a structure obtained by sequentially stacking, on an insulating substrate, a silicon nitride film, a silicon oxide film, a polysilicon thin film with a channel region and source and drain regions facing each other via the channel region, an insulating film, and a gate electrode. The boron concentration decreases from the channel region toward the silicon nitride film in the silicon oxide film region between the channel region and the silicon nitride film. The silicon oxide film region between the channel region and the silicon nitride film is made up of a first region which is in contact with the channel region and has a boron concentration of 1×1016 atoms/cm3 or more, and a second region between the first region and the silicon nitride film, which has a boron concentration of less than 1×1016 atoms/cm3. The first region has a thickness of 200 Å or less.
