Abstract

The invention provides an alignment method of a liquid crystal panel, the liquid crystal panel and a display device. The alignment method of the liquid crystal panel comprises the following steps of forming a first electrode with a slit and a first alignment film covering the first electrode on a first substrate, forming a second electrode on the second substrate and a second alignment film covering the second electrode, irradiating the first alignment film or the second alignment film by using ultraviolet light to form alignment force, and enabling the liquid crystal to drop and be attached to the first substrate and the second substrate, so that a liquid crystal layer is formed between the first substrate and the second substrate. According to the alignment method of the liquid crystal panel provided by the invention, the exposure dark lines at the segmentation positions of the pixels can be reduced, so that the transmittance is improved.

Description

technical field [0001] The invention relates to the technical field of display equipment manufacturing, in particular to an alignment method of a liquid crystal panel, a liquid crystal panel and a display device. Background technique [0002] Liquid Crystal Display (LCD) has many advantages such as thin body, power saving, and no radiation, and has been widely used, such as LCD TV, mobile phone, personal digital assistant, digital camera, computer screen or notebook computer screen, etc. . At present, TFT-LCD liquid crystal panels can be divided into three categories, namely twisted nematic / super twisted nematic (TN / STN) type, in-plane switching (IPS) type and vertical alignment (VA) type. While ultraviolet induced multi-domain vertical alignment (ultraviolet induced multi-domain vertical alignment, UV 2 A) is a photo-alignment technology for VA-type liquid crystal panels. Its name comes from the multiplication of ultraviolet UV and VA mode of liquid crystal panels. Its pr...
