Abstract
The present invention relates to a liquid-crystal (LC) display of the PSA (polymer sustained alignment) type, and to novel polymerisable compounds and novel LC media for use in PSA displays.
Claims25
A polymer sustained alignment-vertical alignment or polymer sustained alignment-optically compensated bend liquid-crystal display comprising:
- a liquid-crystal cell comprising two substrates, where at least one substrate is transparent to light and at least one substrate has an electrode layer, and a layer, located between the substrates, of a liquid-crystal medium comprising a polymerized component and a low-molecular-weight component, where the polymerized component is obtainable by polymerization of one or more polymerizable compounds between the substrates of the liquid-crystal cell in the liquid-crystal medium with application of an electrical voltage,
- wherein all polymerizable compounds present in the liquid-crystal medium contain exclusively methacrylate group(s) as polymerizable group(s), and the low-molecular-weight component comprises one or more mesogenic or liquid-crystalline compounds containing one or more alkenyl groups which are stable with respect to polymerization of methacrylate groups.
