ABSTRACT:
Multi-domain liquid crystal cells having twist angles less than 90 degrees, and LCDs containing such liquid crystal cells, are provided. Such liquid crystal cells are stable, particularly at zero and high fields, and provide wide viewing angles. Also provided are methods of using an adjustable particle beam in combination with a mask to generate multi-domains alignments. Such methods are useful for producing liquid crystal cells in general, and for producing the novel multi-domain low twist angle liquid crystal cells of the present invention in particular.
