This paper presents a simple method to produce radial liquid crystal (LC) alignment layers using circular rubbing of poly( N -vinyl carbazole) (PVK) films. The produced layer can be used for fabricating axially symmetric homogeneous–radial, homeotropic–radial and radial–radial LC alignment devices b...
