ABSTRACT:
In a liquid crystal display device comprising a plurality of layer domains of a liquid crystal material between a first and a second substrate member with two adjacent ones of which domains made to serve as a first layer domain of a first twist angle of liquid crystal orientations and as a second layer domain of a second twist angle of liquid crystal orientations, an angle between the first and the second twist angles is selected between 80.degree. and 100.degree. with the liquid crystal material made to have a chiral pitch between 20 micrometers and 200 micrometers in each of the first and the second layer domains. Preferably, the liquid crystal orientations have a pretilt angle between 0.degree. and 1.50.degree. at an interface between the liquid crystal material layer domains and at least one of the first and the second substrate members.
