Abstract

The invention provides a vertical photo-alignment method and a liquid crystal display panel manufacturing method. According to the vertical photo-alignment method, pixel areas are designed to be in a square shape, each pixel area is divided into four sub areas which are the same in size, each pattern unit, corresponding to the corresponding pixel area, on the corresponding photomask comprises a light-transmitting area and a shading area, and the shape and size of each light-transmitting area are the same as the shape and size of one of the sub areas of the corresponding pixel area; firstly, the photomasks are utilized to conduct ultraviolet light irradiation on one of the sub areas in the corresponding pixel area according to a certain irradiation angle, and the photo-alignment direction of the sub area is obtained; then, the positions of the photomasks and the linear ultraviolet light irradiation direction are maintained unchanged, a base plate is rotated, ultraviolet light irradiation is sequentially conducted on the other three sub areas of the corresponding pixel area, and the corresponding pixel area is made to have four sub areas which are different from one another in photo-alignment direction. The vertical photo-alignment method and the liquid crystal display panel manufacturing method are high in photo-alignment precision, simple in method and low in cost.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a vertical light alignment method and a manufacturing method of a liquid crystal display panel. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) is one of the most widely used flat panel displays at present, and a liquid crystal panel is a core component of the liquid crystal display. A liquid crystal panel is usually composed of a color filter substrate (ColorFilterSubstrate, CFSubstrate), a thin film transistor array substrate (ThinFilmTransistorArraySubstrate, TFTArraySubstrate), and a liquid crystal layer (LiquidCrystalLayer) disposed between the two substrates. Generally, pixel electrodes and common electrodes are respectively arranged on the array substrate and the color filter substrate. When a voltage is applied to the pixel electrode and the common electrode, an electric field will be generated in the liquid crystal lay...
