Problems solved by technology

Each product adopts different particle sizes of supports according to different designs. Due to the inconsistency of particle sizes of supports used in different products, it is necessary to prepare binders containing different supports (also called glue adjustment). In addition Different products produced on the production line need to be replaced with adhesives containing different supports, which increases the time and work flow of the production line changeover, which is not conducive to the rapid changeover of the production line to promote lean production, and the adjusted one contains supports The shelf life of the adhesive is only 3 to 8 days. After replacing the product, the remaining adhesive containing the support can only be scrapped if it is not used up within the shelf life, resulting in a waste of certain production materials.

Abstract

The invention discloses a color filter substrate, wherein a display area of the color filter substrate is provided with first spacers, and a seal agent coating area of the color filter substrate is provided with second spacers. The invention further discloses an LCD (liquid crystal display) panel, wherein a display area of the color filter substrate of the LCD panel is provided with first spacers, a seal agent coating area of the color filter substrate is provided with second spacers, and the color filter substrate is combined with an array substrate of the LCD panel by virtue of a binder coated in the seal agent coating area. The second spacers in the LCD panel play a supporting role, and accordingly, the thickness of the LCD panel is kept uniform. Meanwhile, the invention further discloses manufacturing methods for the color filter substrate and the LCD panel.

Description

technical field [0001] The invention relates to the production field of liquid crystal panels, in particular to a color filter substrate, a liquid crystal panel and a manufacturing method thereof. Background technique [0002] Liquid crystal display is the most widely used flat-panel display due to its high display quality, low price, and easy portability. Monitors with high-resolution color screens are widely used as monitors or laptop screens. [0003] The liquid crystal display commonly used at present usually consists of upper and lower substrates and a middle liquid crystal layer, and the substrate is composed of glass and electrodes. In addition, a traditional liquid crystal display panel is composed of a color filter substrate, a thin film transistor array substrate (thin film transistor array substrate, TFT array substrate, array substrate), and a liquid crystal layer (liquid crystal) disposed between the two substrates. crystal layer). [0004] In recent years, t...
