Preface
Since the discovery of liquid crystals in 1888 by Friedrich Reinitzer and the evidence of their existence as thermodynamically stable phases by Otto Lehmann at the beginning of this century basic research on the chemistry and physics of these mesophases has been carried out for three decades mainly in Germany and France. In the 1940s, 50s the interest in liquid crystal research, however, relaxed somewhat. But this situation abruptly changed in the middle of the 1960s when G.H. Heilmeier gave the first indication for an application of liquid crystals in electrooptical display technology. This aspect immensely stimulated liquid crystal research and led to an explosive growth of publications in this field over the last 25 years. By 1959, about 1400 compounds that form liquid crystalline phases were known; by 1992 this number had increased to about 50000. In portable devices like wristwatches, pocket calculators, measuring instruments, and laptop
