Patent ID: 8778466

Claim:
A polymer sustained alignment (PSA) liquid-crystal (LC) display comprising: an LC cell having two substrates, wherein at least one substrate is transparent to light and at least one substrate has an electrode layer, and a layer of a low-molecular-weight LC medium positioned between said substrates, said LC medium comprising one or more polymerised compounds, wherein said polymerised compound(s) is (are) obtained by polymerisation of one or more polymerisable compounds between the substrates of the LC cell in the LC medium with application of an electrical voltage, wherein at least one of the polymerisable compounds has a biaryl structural element of Formula I which is linked at at least one position to one or more polymerisable groups, optionally via an organic group or a spacer group, wherein A and B are each, independently of one another, an aromatic or fully or partially saturated ring, in which, in the individual rings, one or more CH groups are each optionally replaced by N, and one or more CH 2 groups are each optionally replaced by O or S in such a way that O and/or S atoms are not linked directly to one another, and where the individual rings may also be mono- or polysubstituted, and wherein said at least one polymerisable compound which contains a structural element of Formula I is employed as a racemate.
