An alignment film coating machine and a coating method are provided. The alignment film coating machine includes an equipment for carrying a substrate, a spray head for spraying PI droplets, and an air knife disposed on the equipment and located on one side of the spray head. The air knife is used for moving along the equipment and blowing uniform impact air curtain to the PI droplets after the spray head sprays the PI droplets on the substrate. By adding the air knife into the alignment film coating machine, the diffusion ability of the PI droplets is improved due to the uniform impact air curtain blown by the air knife. The resistance in diffusion is overcome. The PI droplets enter the via hole. Mura, which is induced by a relatively thicker PI film around the via hole as a result of the accumulation of the PI droplets, is prevented.

The present invention provides a photosensitive monomer of which hydrogen atoms of benzene ring of a hard core are substituted by fluorine atoms to increase the electronegativity of the hard core, so that the curing voltage of the curing process is reduced. The photosensitive monomer of the present invention not only reduces the curing voltage and curing time of the curing process of liquid crystal panels, but also increases the pretilt angle of liquid crystal molecules to reduce the response time of a liquid crystal display, so that image sticking and MURA phenomenon are reduced.

Photosensitive monomer and liquid crystal panel

The present invention provides a polymerizable monomer, a liquid crystal composition containing the polymerizable monomer and a vertical alignment liquid crystal panel. The polymerizable monomer which the present invention provides may generate free radicals more easily under the UV exposure, so as to solve the RM residue due to the improvement of the curing ability of the RM and thus improve the image sticking issue of the liquid crystal panel.

Liquid crystal composition and liquid crystal panel

The present invention discloses a reactive monomer of liquid crystal. The reactive monomer of liquid crystal is added with at least one fluoro group. Because hydrocarbon bonds of a side chain of polyimide surface of an alignment film has a fluorophobic effect, the fluoro group of the reactive monomer of liquid crystal can lower the interaction between the polyimide surface of the alignment film and the reactive monomer of liquid crystal to thus evenly deposit the liquid crystal composition containing the reactive monomers of liquid crystal onto the polyimide surface of the alignment film. Thus, it can avoid from occurring the phenomenon of drop Mura defect occurred during implementing the ODF technology.
