Problems solved by technology

[0004] Since the color resistance is set on the upper substrate (array substrate), in order to prevent the color resistance from absorbing ultraviolet light, the ultraviolet light is irradiated on one side of the lower substrate (color filter substrate), however, the reactive monomers on the edge of the liquid crystal panel The reaction is still incomplete. In the process of Image Sticking, the reaction monomer undergoes a secondary reaction to cause a pre-tilt angle shift, and a whitening phenomenon is formed at the edge of the liquid crystal panel.

Abstract

The invention discloses a method for manufacturing aggregate-stabilized vertical alignment liquid crystal display panel, which comprises a liquid crystal preparation step, a substrate preparation step, a first irradiation step, a second irradiation step and a third irradiation step. In the third irradiation step, a third ultraviolet light is irradiated from a second side of the liquid crystal panel to aggregate the reactive monomer of the liquid crystal layer in an edge area.

Description

technical field [0001] The invention relates to a manufacturing method of a liquid crystal display panel, in particular to a manufacturing method of an aggregate-stabilized vertical alignment liquid crystal display panel. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (TFT-LCD) occupies a mainstream position in the current flat panel display field due to its advantages of high chromaticity, small size, and low power consumption. As far as TFT-LCD display panels currently on the mainstream market are concerned, they can be divided into three types, namely Twisted Nematic (TN) or Super Twisted Nematic (STN) type, in-plane switching (In -Plane Switching (IPS) type, and Vertical Alignment (Vertical Alignment, VA) type. Compared with other types of liquid crystal displays, the VA type liquid crystal display has a very high contrast ratio, and has a very wide application in large-size displays, such as televisions. Among them, the polymer stabilized ve...
