Abstract
The invention relates to photo-alignment layers for planar alignment of liquid crystals. Photo-alignment layers according to the invention exhibit a characteristic wavelength dependency of the dichroism in the uv wavelength range. The invention further relates to methods for providing such photo-alignment layers as well as liquid crystal devices containing them.
