Abstract

The invention discloses a liquid crystal panel and an alignment film thereof. The alignment film is made of modified polyimide with conjugated double bonds on a lateral chain. The resistance value of the polyimide is reduced through the characteristic of the conjugated double bonds, so that the resistance value of the alignment value is less than that of a liquid crystal material in the liquid crystal panel, and the imidization rate of the modified polyimide alignment film is improved. Charged ions of a liquid crystal layer are conducted through the conjugated double bonds of the lateral chain of the modified polyimide for preventing the ion concentration of partial region from increasing and further improving the problem of image sticking.

Description

technical field [0001] The present invention relates to a liquid crystal panel and its alignment film, in particular to a modified polyimide alignment film (Polyimide alignment film), which can improve the problem of image sticking in liquid crystal screens. Background technique [0002] Liquid Crystal Display (LCD) has been widely used in various electronic products, such as figure 1 As shown, the main components of the liquid crystal panel 10 include two opposite substrates 11 , 12 ; a liquid crystal layer 13 sandwiched between the two substrates 11 , 12 ; and two alignment films 14 , 15 . The alignment films 14 and 15 are disposed on opposite inner surfaces of the two substrates 11 and 12 and adjacent to the liquid crystal layer 13 . [0003] Liquid crystal displays are often used to display dynamic or static images. When the liquid crystal display displays a static image for a long time and then displays other images, it is easy to have an image or outline left over fr...
