Abstract: Cell with a double liquid crystal layer using the electrically controlled birefringence effect and process for producing a negative optical anisotropy uniaxial material usable in said cell.The cell can comprise two crossed rectilinear polarizers, three glass plates provided with transparent electrodes and placed between said polarizers, two liquid crystal layers between the plates and, between a plate and a polarizer, a sheet of the medium, whose extraordinary axis is perpendicular to the plates. This sheet can be obtained by heating a thermoplastic polymer up to the isotropic state, under a uniform pressure on the polarizers, cooling and eliminating the pressure. The cell is designed in such a way that the molecules of the respective layers tilt in two directions forming the same angle with the homeotropy direction, when an exciting voltage is applied between the electrodes, said directions, viewed in projection on a plate, also being opposite in the main observation plane.Application to the production of television screens.

Abstract: A process for the sequential control of a liquid crystal display means having different optical responses in alternating and steady fields. This process consists of applying to one side of a first electrode an a.c. potential V.sub.1 and to the other side an a.c. potential V.sub.2, with V.sub.2 -V.sub.1 constant, so that only line Y parallel to the sides of the first electrode is exposed to a reference potential V.sub.0 ; applying to one side of a second electrode an a.c. potential V.sub.3 and to the other side an a.c. potential V.sub.4, with V.sub.4 -V.sub.3 constant, so that only the line X parallel to the sides of the second electrode, intersecting the first, is exposed to V.sub.0 ; and applying a d.c. potential V.sub.5 to the two sides of one electrode, so that liquid crystal zone XY defined by the intersection of lines X and Y is only subject to potential V.sub.5 and that outside the zone the liquid crystal is subject to an a.c. potential difference, the displayed state of the zone resulting from a positive polarity of V.sub.5, the undisplayed state resulting from a negative polarity of V.sub.5 and the maintaining of a state resulting from the elimination of V.sub.5.
