Abstract

A method for manufacturing a liquid crystal display panel, comprising: applying an isotropic alignment film on a color film substrate and an array substrate (S101); irradiating the alignment film with linearly polarized ultraviolet light so that the isotropic alignment film is converted into an anisotropic alignment film to form a pre-tilt angle of the alignment film (S104); adding, drop-by-drop, liquid crystal molecules in the color substrate having a sealing frame, the liquid crystal molecules being doped with thermally reactive monomers (S105); aligning and bonding the color film substrate and the corresponding array substrate (S106); providing an adhesive frame on the periphery of the liquid crystal display panel (S107); and thermally curing the adhesive frame, whilst causing the thermally reactive monomers in the liquid crystal molecules to form a polymer on the surface of the alignment film, so as to improve the anchoring force on the liquid crystal molecules from the alignment film.

Description

technical field [0001] The invention relates to the field of panel fabrication, in particular to a fabrication method of a liquid crystal display panel. Background technique [0002] With the development of science and technology, people have higher and higher requirements for the display effect of the liquid crystal display panel. In order to improve the display response speed of the liquid crystal display panel, the array substrate and color filter substrate of the liquid crystal display The liquid crystal molecules provide a pre-tilt alignment film. [0003] The existing alignment films are all made by photo-alignment, that is, a layer of isotropic alignment film is coated on the surface of the array substrate and the color filter substrate, and then the alignment film is irradiated with ultraviolet polarized light, so that the isotropic The homogeneous alignment film reacts chemically and becomes anisotropic, thereby aligning the liquid crystal molecules. By using phot...
