Abstract
In a provided vertical alignment method, a pixel region, and the pixel region is divided into four sub regions of equal sizes which each is designed to be a square, and a pattern unit on the mask comprises a photic region corresponding to one sub region and a shading region corresponding to the other three sub regions in shape and size. The mask is employed to implement linear UV light irradiation to one sub region according to a certain irradiation angle to obtain a alignment direction of the one sub region, and then, the position of the mask and the certain irradiation angle of the irradiation are maintained to be unchanged. By rotating the pixel region 90° with three times, and the irradiation is implemented to the other three sub regions. Accordingly, the four sub regions have four alignment directions different from one another.
