Abstract A liquid crystal display (LCD) cell comprising a twist nematic liquid crystal disposed between two electrode plates and polarizers and having a positive dielectric anisotropy. The optical path difference .DELTA.n.d is 0.2 to 0.7 µm. The absolute value of the twist angle .PHI. can be between 10° and 80°, the angle ? between the polarizers can be between 80° and 110° and the angle .THETA. between the surface orientation direction and the polarization direction on the screen on the light incidence side can be between -10° and 60°, preferably so that the polarizers are symme- trical of the nematic directors.
