A liquid crystal alignment process comprises 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; 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 for polymerizing the first monomer material and the second monomer material to form at least one type of liquid crystal alignment polymer on opposite surfaces of the first and second substrates. The liquid crystal alignment process is capable of improving the efficiency of exposure procedure, reducing time to manufacture products, and is capable of solving the problems of high costs and waste pollution.

Liquid crystal alignment process

A liquid crystal display panel includes an active component array substrate, a color filter substrate, a pair of alignment films and a liquid crystal layer. The active component array substrate has a first plane. The color filter substrate has a second plane opposite to the first plane. The alignment films are disposed on the first plane and the second plane respectively. The liquid crystal layer is disposed between the alignment films and includes a liquid crystal material, a photo initiator and a first monomer material. The liquid crystal material, the photo initiator and the first monomer material are mixed together. When being irradiated by ultraviolet light, the photo initiator enables the first monomer material to react in a polymerization to form the alignment films.
