摘要：

Contained in this report are studies on liquid crystal (LC) alignment capabilities and the generation of pre-tilt angles with ion beam (IB) exposure on a diamond like carbon (DLC) thin film layer. A high pre-tilt angle of 3.5degrees via IB exposure on the DLC thin film layer can be obtained. Superior LC alignment via the IB alignment method on the DLC thin film layer was observed up to an annealing temperature of 200degreesC. A high LC pre-tilt angle and good thermal stability during LC alignment via the IB alignment method on the DLC thin film layer can be achieved.
