ABSTRACT:
The nematic liquid crystal cell weakly doped by a chiral solute and of the electrically controlled birefringence type. Doping is such that the resulting cholesteric liquid crystal twist exceeds approximately twice the thickness of the liquid crystal coating and is less than approximately 8 times said thickness. Moreover, one of the sides of the cell is to be exposed to incident light and at least on said side, the cell comprises an advantageously linear polarizer. Application to the production of displays for moving images or pictures.
