Abstract
A method for fabricating a liquid crystal cell and related device includes providing an alignment layer of a light sensitive material on a substrate; and exposing the alignment layer to unpolarized or partially polarized light, to provide pretilt for the molecules of the alignment layer.
Claims17
A liquid crystal display device, comprising:
- an alignment layer provided on a substrate, said alignment layer including a light sensitive material and having an orientation dependent upon an exposure to obliquely incident light;
- and
- a liquid crystal material adjacent said alignment layer, said liquid crystal material having molecules having a pretilt, said pretilt having a magnitude depending on said orientation of the alignment layer.
Dependencies are inferred from the claim text.
