Abstract
A liquid crystal display device includes transparent electrodes mutually extending in parallel, and lead patterns used as terminals leading from ends of the transparent electrodes, both formed on a cell substrate produced by separating a large glass substrate. In the device, extension patterns leading from other ends of the transparent electrodes are formed on the cell substrate, and minute gaps for discharging static electricity accumulated in the transparent electrodes during a production process are formed at portions of the extension patterns outside an effective display region. The liquid crystal display device is produced such that transparent electrodes, lead patterns used as terminals leading from ends of the transparent electrodes, extension patterns leading from the other ends of the transparent electrodes, and an identical potential pattern outside the cell substrate-formed patterns being conductive with the transparent electrodes are formed with a plurality of cell substrate-formed regions being adjacently positioned, minute gaps narrower than the gap between the adjacent transparent electrodes are formed within each cell substrate-formed region outside an effective display region, and the large glass substrate is cut so that a plurality of cell substrates are separately formed.
