Abstract
Liquid crystal display with a liquid crystal layer which can be switched between two optically different states. Two support plates have the surfaces facing each other coated with an electrically conducting layer as well as an orientation layer with at least one orientation layer consisting of a polymer. The plates enclose the liquid-crystal layer. The polymer is liquid-crystalline and can be switched to the off-state and on-state--in the process of which it generates the rest state of the liquid-crystal layer in the off-condition and, in the on-condition, at least enhances the excited state of the liquid-crystal layer.
