PCT No. PCT/EP89/00178 Sec. 371 Date May 15, 1989 Sec. 102(e) Date May 15, 1989 PCT Filed Feb. 27, 1989 PCT Pub. No. WO89/08691 PCT Pub. Date Sep. 21, 1989.Supertwist liquid crystal display elements with excellent steepness of the characteristic are obtained, if the nematic liquid crystal mixture satisfies the following conditions: a nematic phase range of at least 60 DEG C., a viscosity of 30 mPa.s or lower, and DELTA epsilon / epsilon ORTHOGONAL <2.0, where DELTA epsilon is the dielectric anisotropy and epsilon ORTHOGONAL is the dielectric constant in the direction of the short axis of the liquid crystal molecules.
