Liquid crystal display device substantially free from cross-talk having varistor layers coupled to signal lines and picture electrodes

Claim 1

A liquid crystal display device comprising: a first transparent base; a plurality of picture element electrodes arranged on the first base; a plurality of signal lines for supplying electric signals to the picture element electrodes, and arranged adjacent to and spaced from the picture element electrodes on the first base; a plurality of varistor layers comprising fine varistor particles, through which the picture element electrodes are connected to the adjacent signal lines; a second transparent base arranged in parallel to and spaced from the first base; a plurality of scanning electrodes arranged on the second base, facing and spaced from the picture element electrodes; and a liquid crystal material layer arranged between the picture element electrodes and the scanning electrodes; wherein the distance (l 1 ) between the signal lines and the adjacent picture element electrodes is smaller than the distance (l 2 ) between the signal lines and the corresponding scanning electrodes on the second base whereby said varistor layers connecting the signal lines with the adjacent picture element scanning electrodes exhibit a threshold value voltage (V th ) smaller than a minimum voltage (V min ) under which an electric current is allowed to flow between the signal lines on the first base and the scanning electrodes on the second base through at least portions of the varistor layers extending from the signal lines toward the corresponding scanning electrodes on the second base.
