| description | A liquid crystal alignment film (6), which is arranged on a substrate (1) of a liquid crystal panel. The alignment film (6) at least comprises alignment molecules and photosensitive molecules. The alignment molecules comprise polyamic acid and/or polyimide, and the photosensitive molecules are terphenyl molecules and/or terphenyl molecules with substituent groups; and the mass percentage of the alignment molecules to the photosensitive molecules is 3-7% : 0.0002-0.2%. Further provided are a manufacturing method for such an alignment film (6) and a liquid crystal panel manufactured using such an alignment film (6). By introducing photosensitive molecules to optimize the function of an alignment film material, the reaction rate of a polymerizable monomer can be adjusted to a suitable production range, and the reaction uniformity of the polymerizable monomer within a reaction region can be improved, thereby effectively reducing mura conditions, and improving the optical grade of the liquid crystal panel.
