Abstract[English]
The present invention relates to an LC medium comprising two or more polymerizable compounds one of which has a monocyclic group, to its use for optical, electro-optical and electronic purposes, in particular in LC displays, especially in LC displays of the PSA (polymer sustained alignment) or SA (self-aligning) mode, to an LC display of the PSA or SA mode comprising the LC medium, and to a process of manufacturing the LC display using the LC medium, especially an energy-saving LC display and energy- saving LC display production process.[French]
La présente invention concerne un milieu à cristaux liquides comprenant deux ou plusieurs composés polymérisables dont l'un possède un groupe monocyclique, son utilisation à des fins optiques, électro-optiques et électroniques, en particulier dans les écrans à cristaux liquides, notamment dans les écrans à cristaux liquides du mode PSA (alignement soutenu par polymère) ou SA (auto-alignement), un écran à cristaux liquides du mode PSA ou SA comprenant le milieu à cristaux liquides, et un procédé de fabrication de l'écran à cristaux liquides utilisant le milieu à cristaux liquides, notamment un écran à cristaux liquides à économie d'énergie et un procédé de production de l'écran à cristaux liquides à économie d'énergie.
