Liquid crystal display device
Abstract
A liquid crystal display device includes first and second substrate (24) and a liquid crystal layer sealed between the substrates. A plurality of pixel elements (28) are formed in a matrix pattern on the first substrate, and a plurality of driving nonlinear resistance elements (16) are formed on the first substrate and electrically connected to the pixel electrodes, respectively. a plurality of parallel wiring electrodes (12) 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 (20) and has a pair of divided ends (12a, 12b). Protecting nonlinear resistance elements (30) 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.
