Abstract
Liquid crystal (LC) alignment capabilities with ion beam (IB) exposure on a diamond like carbon (DLC) layer were studied. A high pretilt angle of 3.5° with IB exposure on the DLC layer can be obtained. Superior LC alignment with the IB alignment method on the DLC layer was observed until an annealing temperature of 200°C. Also, excellent voltage-transmittance (V-T) curve of the ion beam aligned twisted nematic (TN) cell with oblique ion beam exposure on the DLC surface for 1 min was observed. The fast response time of the ion beam aligned TN cell with oblique ion beam exposure on the DLC surface for 1 min can be achieved. The residual DC property of the ion beam aligned TN cell with ion beam exposure on the DLC layer for 1 min is almost same as that of the rubbing aligned TN cell on a rubbed polyimide (PI) surface.
