Liquid crystal display panel and method for making the same

Abstract

The invention provides a liquid crystal display panel and a production method thereof, wherein, the liquid crystal display panel comprises a first substrate, a second substrate, a liquid crystal layer arranged between the first substrate and the second substrate, a patterned black matrix layer arranged on the surface of the first substrate, a patterned first color filter layer arranged on the surface of the first substrate, a plurality of first spherical spacers and a plurality of second spherical spacers, wherein, the protruding part of the patterned first color filter layer covers part of the patterned black matrix layer. The first spherical spacers are arranged on the surface of the patterned black matrix layer, the second spherical spacers are arranged on the surface of the protruding part of the patterned first color filter layer, the bottom surfaces of the second spherical spacers and the bottom surfaces of the first spherical spacers are positioned on the different planes in the liquid crystal display panel. The liquid crystal display panel can improve the allowable range of the liquid crystal filling amount.

Description

Technical field [0001] The present invention relates to a liquid crystal display panel and a manufacturing method thereof, and more particularly to a liquid crystal display panel including a hybrid ball spacer structure and a manufacturing method thereof. Background technique [0002] With the development of liquid crystal display technology becoming more and more mature, liquid crystal display devices have been widely used in various information products, such as portable information products such as notebook computers, personal digital assistants, and mobile phones, and have even gradually replaced traditional cathode ray tube displays. The main components of the liquid crystal display device include a liquid crystal display panel, which includes two transparent substrates and a liquid crystal layer arranged between the transparent substrates, and the gap between the transparent substrates is maintained through a sealant and a spacer. The current commonly used liquid crystal fi...

AI Technical Summary

Problems solved by technology

Although the liquid crystal display panel 20 only needs one photolithography process to form the photoresist spacers 28, an additional process is still required to form the metal matrix layer 30, so the liquid crystal display panel 20 still has the disadvantage of complicated processes.

[0005] In addition, traditional photoresist spacers have the disadvantage of high material cost, so how to make spacers with different heights or spacers between transparent substrates with less cost and simple process to improve liquid crystal filling The allowable range of the amount is still one of the topics that the liquid crystal display panel industry needs to study urgently
