  • Publication number: 20120099063
    Abstract: An alignment film for spontaneously aligning liquid crystal is used to align a plurality of liquid crystal grains and comprises a first substrate, a second substrate, a liquid crystal layer, a first transparent conductive layer, a second transparent conductive layer, a first alignment film and a second alignment film. The first and second alignment films are made of anodic aluminum oxide and have a plurality of nanometric pores respectively. The liquid crystal layer is interposed between the first and second alignment films. The nanometric pores of the first and second alignment films induce the liquid crystal grains to align spontaneously. Thereby, the problems of contamination, denatured material and non-uniform alignment, which are caused by the conventional liquid crystal alignment technology, can be solved. Further, the fabrication process of the alignment film can integrate with the current LCD process to fabricate a large-size LCD panel.
