Problems solved by technology

Since hydrofluoric acid is an irritating liquid, it is easy to affect the environment
At the same time, the flatness of the surface of the glass substrate cannot be guaranteed during the processing process, which reduces the yield of the product and the cost is high

Abstract

A method of manufacturing a liquid crystal display panel comprises: forming multiple spacers and a frame respectively on the surfaces of a first transfer board and a second transfer board; in a vacuum chamber, adsorbing the first transfer board and a first substrate to integrally form a first substrate assembly, and adsorbing the second transfer board and a second substrate to integrally form a second substrate assembly; forming a thin-film transistor array on the first substrate and a color filter layer on the second substrate; reversing the first substrate assembly so that the TFT array and the color filter layer are arranged oppositely, and providing frame glue and filling liquid crystal between the first substrate and the second substrate, and attaching them into a whole; laser-cutting a first frame to separate the first transfer board and the first substrate, cutting a second frame to separate the first transfer board and the second substrate, and removing the first transfer board and the second transfer board.

Description

technical field [0001] The present invention relates to a method for manufacturing a liquid crystal display panel. Background technique [0002] In the manufacturing process of the existing liquid crystal display panel, liquid crystal molecules are poured on the glass substrate forming the TFT array and between the glass substrate with the color filter layer to form the liquid crystal display panel. However, in order to meet the user's demand for thinner and lighter products, how to make the liquid crystal display device thinner and lighter is still one of the important topics of current research in the industry. [0003] In the prior art, a chemical reaction between hydrofluoric acid (HF) and glass is used to reduce the thickness of the glass substrate, so as to realize the thinning of the glass substrate. As hydrofluoric acid is an irritating liquid, it is easy to have an impact on the environment. At the same time, the flatness of the surface of the glass substrate cann...
