Abstract

Orientational electrooptic effects in liquid crystals (LC) have found wide practical use in information display devices. Obvious advantage of liquid crystals based on `twist effect' has been universally recognized. This advantage is mainly connected with the fact that in the case of normal incidence of light beam the geometry of `twist' elements is not characterized by any phenomena related to dispersion of refractive index, and that such LCs cope well with controlling white light beams. The use of orientational effects associated with the changing of birefringence is limited by a more rigid fixing of modulation characteristics to the light wavelength. Using of thin LC layers allows to take away this limitation.
