A method suitable for producing large scale light modulating liquid crystal devices having a very thin layer, say 15µm thick, of liquid crystal containing material (6), preferably a mixture capable of forming polymer stabilised liquid crystal ("PSCT") material, sandwiched between two substrates (2, 4), at least one of which is glass. The liquid crystal containing material (6) is applied to the first substrate (2) before the second substrate (4) is brought into contact, and the substrates (2, 4) are compressed, for instance between rollers (18, 22), to achieve the required thickness of liquid crystal material. Spacers keep the substrates (2, 4) the requisite distance apart. Liquid crystal containing material (6) capable of forming PSCT material also requires polymerising, say, by exposing the compressed sandwich to UV radiation.

Cette invention se rapporte à un procédé adapté à la fabrication à grande échelle de dispositifs à cristaux liquides modulateurs de lumière, dotés d'une très fine couche, de l'ordre de 15 µm d'épaisseur, d'une matière (6) contenant des cristaux liquides et constituée de préférence d'un mélange susceptible de former un matériau à cristaux liquides stabilisé par un polymère ("PSCT"), pris en sandwich entre deux substrats (2, 4), l'un au moins de ces substrats étant constitué de verre. On applique ladite matière (6) contenant les cristaux liquides sur le premier substrat (2) avant d'amener le second substrat (4) en contact puis on comprime les deux substrats (2, 4), par exemple entre deux cylindres (18, 22), jusqu'à l'obtention de l'épaisseur requise de la matière à cristaux liquides. On maintient les deux substrats (2, 4) à une distance respective requise au moyen de séparateurs. Il est également nécessaire de polymériser ladite matière (6) contenant les cristaux liquides et susceptible de former le matériau PSCT en exposant la structure en sandwich comprimée à un rayonnement ultraviolet.
