Polymerizable compounds useful for making liquid crystal displays of the polymer sustained alignment type comprise polymerizable groups bonded to a biaryl structure

摘要

Polymerizable compounds (II) comprising polymerizable groups bonded to a biaryl structure (I), either directly or via an organic group or spacer group, are new. Polymerizable compounds comprising polymerizable groups bonded to a biaryl structure of formula (I), either directly or via an organic group or spacer group, are new. A, B : optionally substituted aromatic or at least partially saturated rings in which CH groups can be replaced by N and CH 2 groups can be replaced by O or S. Independent claims are also included for: (1) liquid crystal medium comprising a polymerized compound (II); (2) liquid crystal display of the polymer sustained alignment type comprising a liquid crystal medium as above in a cell between two substrates, including a transparent substrate and a substrate with an electrode layer, where the compound (II) is polymerized within the cell by applying an electrical voltage.
