Abstract:
A method of generating a patterned alignment direction on an alignment surface for a liquid crystal display cell comprising:forming a first alignment direction on said alignment surface;forming a second alignment direction on said alignment surface;said first and said second alignment directions are formed by a sequence of treatments selected from a group consisting of a first sequence and a second sequence;said first sequence comprises a first step of rubbing said alignment surface and thereafter a second step of selectively exposing said alignment surface to a treatment selected from a group consisting of exposure to electromagnetic radiation and exposure to a particle beam;said second sequence comprises a first step of exposing said alignment surface to a treatment selected from a group consisting of electromagnetic radiation and a particle beam thereafter selectively exposing said alignment surface to another particle beam;said particle beam and said another particle beam are said first particle beam and said second particle beam are directed at said surface at an adjustable energy, at an adjustable angle with respect to said alignment surface and at an adjustable time to adjust the pretilt angle of a liquid crystal molecule with respect to said alignment surface.
