Manufacturing method of oriented film and LCD panel

Abstract

The invention discloses a manufacturing method of an oriented film, comprising: forming a solidifiable material layer with a side chain on a first substrate; sticking a first substrate and a second substrate to cause the solidifiable material layer to face the second substrate; filling a liquid crystal layer between the first substrate and the second substrate to ensure that the liquid crystal layer can be contacted with the solidifiable material layer; applying an electric field to cause the side chain to face a preset direction; solidifying the solidifiable material layer to cause the side chain to be in crosslinking and be solidified, and ensuring that the solidifiable material layer has liquid crystal orientation. The manufacturing method of an LCD panel comprises: forming a first UV-curing material layer with a first side chain on the first substrate; forming a second UV-curing material layer with a second side chain on the second substrate; sticking the first substrate and the second substrate to cause the first UV-curing material layer to face the second UV-curing material layer; filling the liquid crystal layer between the first substrate and the second substrate; causing the liquid crystal layer to contact with the first UV-curing material layer and the second UV-curing material layer; applying a first electric field to cause the first side chain to face the first preset direction; and photocuring the first UV-curing material layer to cause the UV-curing material layer to have the first orientation.

Description

technical field [0001] The present invention relates to a method for manufacturing an alignment film, and in particular to a method for manufacturing an alignment film for a liquid crystal display panel. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) has gradually replaced traditional cathode ray tube (Cathode Ray Tube, CRT) display device due to its advantages such as light and thin body, low power consumption and no radiation, and is applied to various electronic products. For liquid crystal display devices, how to simplify the manufacturing process and save the manufacturing cost has always been an urgent need to be solved. [0003] Generally speaking, the manufacturing process of a liquid crystal display device mainly includes an array manufacturing process (Array Process), a panel manufacturing process (Cell Process) and a module manufacturing process (Module Process). Among them, the array manufacturing process is mainly to form ele...

Problems solved by technology

[0005] Since the known technology uses a contact method to form the alignment film, that is, rubbing the alignment film to form dents, powder debris will remain in the process, requiring washing equipment to wash, thus increasing the manufacturing process steps and costs

In addition, other unexpected dents or scratches may occur during friction, which will reduce the yield, and the electrostatic problem caused by friction may also easily cause damage to the circuit on the substrate.

In addition, orientation equipment can also increase production costs
