Abstract
A liquid crystal display device capable of displaying clear images without cross-talk, includes (a) a first transparent base, (b) a plurality of picture element electrodes on the first base (a), (c) a plurality of signal lines on the first base (a), (d) a plurality of varistor layers connecting the picture element electrodes (b) to the signal lines (c) therethrough, (e) a second transparent base in parallel to the first base (a), (f) a plurality of scanning electrodes on the second base (e), and (g) a liquid crystal material layer arranged between the picture element electrodes (b) and the scanning electrodes (f), and is characterized in that the scanning electrodes (f) have a size, shape and location satisfying a relationship with the varistor layers (d) such that a plurality of vacant spaces are formed between the scanning electrodes (f) and the varistor layers (d) face the vacant spaces but not the scanning electrodes.
