Abstract:
1. A liquid crystal alignment process comprising steps of: providing a first substrate and a second substrate to form a liquid crystal accommodating space therebetween; pouring a liquid crystal composition into the liquid crystal accommodating space, the liquid crystal composition comprising liquid crystal molecules, a first monomer material, and a second monomer material, wherein the second monomer material is a non-polar monomer material having a lipophilic structure and the first monomer material is a polar monomer material having a hydrophilic structure; applying a voltage difference to the first and second substrates for arranging the liquid crystal molecules at a pre-tilt angle; and exposing the liquid crystal composition by mixed multi-spectrum rays including rays of at least two spectrums for polymerizing the first monomer material and the second monomer material to form two second polymer alignment layers on two opposite surfaces of the first and second substrates and two first polymer alignment layers on two opposite surfaces of the two second polymer alignment layers.
