Abstract
Official abstract text for this publication.
The present invention relates to a liquid-crystal (LC) display of the PS (polymer stabilized) or PSA (polymer sustained alignment) type, and to polymerizable compounds and LC media for use in PS (polymer stabilized) and PSA displays.
First claim
Opening claim text (preview).
The invention claimed is: 1. A polymer-stabilized (PS) or polymer sustained alignment (PSA) liquid crystal (LC) display containing an LC 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 of an LC medium comprising a polymerized component and a low-molecular-weight component located between the substrates, wherein the polymerized component is obtainable by polymerization of one or more…
