Abstract
A method of fabricating multi-domain liquid crystal cell includes the steps of providing first and second substrates, the first and second substrates being coated with photo-alignment layer, covering the substrate with a mask which has a plurality regions having different transmittances, exposing the substrate to vertical light having a first polarization direction, and exposing the substrate to oblique light. The photo-alignment materials include polysiloxane-based materials.
