  • Patent number: 9216562
    Abstract: The present invention discloses an alignment film and the manufacturing method for liquid crystal display panel. The method comprises preparing a first substrate, a second substrate and a liquid crystal, at least one of the first substrate and the second substrate being provided with an alignment film; the material of the alignment film comprising a solvent and a substance dissolved in the solvent, the substance comprising at least one first polymer, the first polymer comprising a main chain and a side chain; folding the first substrate and the second substrate, and injecting the liquid crystal between the first substrate and the second substrate to form a liquid crystal cell; applying voltage to the liquid crystal cell, and then irradiating the liquid crystal cell with UV light. Through the above way, the present invention can reduce the mura phenomenon in the liquid crystal display panel and improve the display quality.
