The present invention relates to a liquid crystal display device comprising a liquid crystal material sandwiched between two confinement plates ( ), the device being characterized by the fact that at least one of the plates ( ) is provided with treatment which defines degenerate or nearly degenerate azimuth anchoring without azimuth orientation memory.

Liquid crystal device comprising anchoring means on at least one confinement plate providing a degenerated orientation

A display device including two parallel transparent plates (,) having transparent electrodes on the inner surfaces thereof and containing a liquid crystal material (,). The device includes means defining a monostable anchoring for each plate (,), means (,) controllable to break at least one of the anchorings, and means for thereafter inducing volume bistability.

Bistable liquid crystal display device in which nematic liquid crystal has monostable anchorings
