Manufacturing method for liquid crystal panel

Abstract

The invention provides a manufacturing method for a liquid crystal panel. The manufacturing method comprises the steps that a first base plate, a second base plate, a first operating line and a second operating line are supplied; the first operating line is used for the manufacturing processes of precuring, curing and exposing, and the second operating line is used for the manufacturing processes of cleaning and drying; a first alignment solution is applied to the first base plate, a second alignment solution is applied to the second base plate, the first alignment solution is a photolysis type high-molecular compound, and the second alignment solution is a photoisomerization high-molecular compound; the first base pate coated with the first alignment solution and the second base plate coated with the second alignment solution are simultaneously supplied to the first operating line, the steps of precuring, curing and exposing are performed on the first operating line, only the exposed first base plate is supplied to the second operating line to be cleaned and dried, and therefore the first base plate and the second base plate which are each provided with an alignment film are formed; frame glue is formed on one of the first base plate and the second base plate; liquid crystal materials are enclosed, and the liquid crystal panel is formed by gluing the first base plate and the second base plate with the frame glue.

Description

technical field [0001] The invention relates to the field of manufacturing liquid crystal displays, in particular to a method for manufacturing a liquid crystal panel. Background technique [0002] The main manufacturing process of the liquid crystal display includes the manufacture of a liquid crystal panel (liquid crystal panel) and the assembly of a liquid crystal display module (LCM). The manufacturing method of the liquid crystal panel is mainly to seal the liquid crystal between the color filter plate as the upper substrate and the thin film transistor array substrate as the lower substrate. For liquid crystal displays, it is very important to align the long axis direction of the liquid crystal molecules with the surface of the substrate at a uniform tilt angle, and the alignment material that can arrange the liquid crystal molecules at a uniform pre-tilt angle is called an alignment film. (alignment layer). In the existing method of manufacturing liquid crystal pane...

Problems solved by technology

In the existing method of manufacturing liquid crystal panels, a photosensitive polymer compound is generally selected as an alignment liquid to manufacture an alignment film, and a light source of a certain wavelength is used to irradiate the photosensitive polymer compound to cause a photochemical reaction to induce liquid crystal molecules to move toward a specific direction. Direction alignment, since there are many types of photosensitive polymer compounds that can be used to manufacture alignment films, and different types of photosensitive polymer compounds have differences in structure, if different types of photosensitive polymer compounds are still used The same manufacturing method will lead to bright spots in the prepared alignment film, which will lead to poor display effect of the liquid crystal panel.
