Abstract:
1. A liquid crystal display (LCD) device comprising: a first substrate having a grooved surface profile; a first alignment film layer of inorganic or organic material formed on said grooved surface of said first substrate and having said grooved surface profile, said first alignment film of inorganic or organic material having 90° meta-stable alignment states eliminated at the surface of said alignment film layer and having an increased 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 a second substrate having a flat surface profile and a second alignment film layer formed thereon, said second substrate aligned opposite said first substrate for forming a plurality of LCD cells having said liquid crystal (LC ) material deposited therein, said LC molecules aligning parallel to the alignment direction of said alignment film layer formed on said grooved surface of said first substrate, wherein aligning the LC molecules parallel to the grooves enables decreased potential energy of said LC material.
