Abstract
Data of the cone angles found with 80 different polymers tested as alignment layers for surface stabilized ferroelectric liquid crystal displays are given. The structural properties of the polymers are correlated with their ability to give good, bistable alignment in such liquid crystal displays. The symmetry of the monomers and crystal surfaces are found to be of major importance, with polymers containing an ester group usually giving the best results.
