Abstract:
1. A method for forming an LCD device comprising: providing a first substrate; generating grooves on said substrate to form a grooved surface profile; depositing a first alignment film layer of inorganic or organic material on said grooved surface of said first substrate in conformance with said grooved surface profile; aligning said first alignment film layer in response to an ion beam applied incident to said grooved surface in an alignment direction parallel to a groove direction, said aligning eliminating 90° meta-stable alignment states at the surface of first alignment film layer of inorganic or organic material and increasing an alignment force for constraining deposited LC material to an alignment direction parallel to the grooves due to enhanced topographic un-symmetry so that alignment other than along the grooved surface profile is energetically unfavorable; and, aligning a second substrate having a flat surface profile and a second alignment film layer formed thereon opposite said first substrate to form a plurality of LCD cells having liquid crystal (LC) molecules deposited therein, said LC molecules aligning parallel to the alignment direction of said first alignment film layer formed on said grooved surface of said first substrate enabling decreased potential energy of said LC material, wherein LC molecules align parallel to the grooves for enhanced LCD performance.
