Abstract: Optically active tetrahydrofuran-2-carboxylic acid esters containing a mesogenic molecular building block are suitable as dopes in liquid-crystal mixtures. They result in liquid-crystalline ferroelectric phases having short switching times and in electroclinic phases having high electroclinic coefficients. A further advantage is that they induce a helix of very low pitch, so they are also suitable for helix compensation in LC mixtures. The compounds are symbolised by the general formula in which the symbols and indices essentially have the following meanings: R = alkyl/alkenyl or tetrahydrofurancarbonyloxy or -thio; j, l and n = zero, 1 or 2; k and m = zero or 1; -A , -A and -A = phenylene, cycloalkylene or corresponding N-, O- or S-containing heterocycles; -M and -M = bridges, such as -CO-O-, -OCH2- or -CH=CH-; and X = O or S.

Abstract: PURPOSE: To effectively suppress optical hysteresis by using a specified liq. crystal switch and a specified display element in a ferroelectric liq. crystal medium display. CONSTITUTION: The liq. crystal switch and display element are used in a display. The display element consists of a ferroelectric liq. crystal medium(FLC), two electrodes, one polarizer, two transparent carrier plates and one orienting layer. This orienting layer has direct electric connection with the electrodes and contains an electrically conductive polymer having repeating untis represented by formula I, wherein each of R and R is H, 1-16C alkyl, 1-16C alkoxy or halogen, X is S or NH, Y is BF4 , PF5 , PO4 , etc., (n) is an integer of 4-100 and (m) is an integer of 1-30. Optical hysteresis phenomenon in the FLC is suppressed.
