Abstract
The present invention provides an alignment method of an FFS liquid crystal display panel. The method includes adding a light-sensitive small-molecule compound in a rubbing alignment material, carrying out rubbing alignment after formation of an alignment film, and afterwards, conducting boxing of the FFS liquid crystal display panel, and then applying an electrical voltage to cause liquid crystal molecules to rotate to a position substantially parallel to a substrate, and carrying out UV irradiation to cause polymerization of the light-sensitive small-molecule compound to form polymer bumps so as to keep the liquid crystal molecules in parallel to the substrate. The liquid crystal molecules, after the alignment, show a pre-tilt angle having a zero angle value and can, under the condition of providing a strong anchoring force of the alignment film, reduce the pre-tilt angle of the liquid crystal molecules and improve quality of displaying of the FFS liquid crystal display panel.
