The product is applied in LCD panel manufacturing process. After irradiation with specific light, the polymer in the product has the ability of alignment, so that the liquid crystal molecules can be arranged along the alignment direction of the molecules. Therefore, the liquid crystal panel can achieve high resolution, wide viewing angle and other high imaging technology quality. Furthermore, our product is tolerant to over-exposure, so that simple facilities even high power LED could be used for alignment. Consequently, the yield and quality of products will be greatly improved.
