Abstract
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 5 nm to 500 μm in a first direction in the plane of the first surface. These layers can be used as anisotropically patterned alignment layers in electro-optical devices and generate an orientational order of at least 0.30.
