Abstract
The invention provides a manufacturing method for VA type LCD panel. The manufacturing method of the present invention adds a photo-initiator and a polymeric monomer to LC material, and uses UV light to irradiate through a mask so that the polymeric monomer polymerizes in accordance with the mask pattern to form polymer protrusions on the array substrate side to achieve the effect similar to protrusion or slit. The method is applicable for the LC molecules to form the pre-tilt angle so that the LC molecules in the panel are lined up along the normal direction. The method is simple, eliminates ITO etching process on the array substrate side, and reduces costs.
