Abstract

An active matrix type liquid crystal display system having a liquid crystal composition being interposed between a first and a second substrates, a plurality of pixel parts being constructed with a plurality of scanning electrodes and a plurality of signal electrodes arranged in a matrix, a switching element being provided in each of the pixel parts, wherein the switching element is connected to a pixel electrode, the pixel electrode and a common electrode being so constructed as operable in keeping the major axes of the liquid crystal molecules parallel to the surface of the substrate. In the pixel part, the signal electrode and the pixel electrode is formed and a shield electrode is formed between the signal electrode and the pixel electrode. The system requires no transparent electrode, being excellent in visual angle characteristic, being high in contrast, being small in cross-talk producing probability.
