LIQUID CRYSTAL ALIGNMENT LAYERS AND METHODS OF FABRICATION

摘要

Methods are provided for making layers with nano-and micro-patterned topographies by-laser action or inkjet printing on a first surface. These topographies have a periodicity of 5nm to 500 μι&eegr; in a first direction in the plane of the first surface. These layers can be used as anisotropic alty patterned alignment layers in electro-optical devices and generate an orientational order of at least 0.30.
