Abstract
A liquid crystal device has a surface alignment structure comprising a random or pseudorandom two dimensional array of alignment features (10) which are shaped and/or orientated to produce a desired alignment. Depending on the geometry and spacing of the features (10), the liquid crystal may be induced to adopt a planar, tilted, or homeotropic alignment.
