Motherboard and substrate of LCD (Liquid Crystal Display) panel and manufacture method of substrate

Abstract

The invention discloses a motherboard and a substrate of an LCD (Liquid Crystal Display) panel and a manufacture method of the substrate. The substrate of the LCD panel comprises a first substrate and a second substrate, wherein a first barrier layer is arranged on the edge of the first substrate, a second barrier layer matched with the first barrier layer is arranged in a corresponding position of the second substrate, and the first barrier layer and the second barrier layer are matched to form a sealing layer. In the technical scheme of the embodiment, through the barrier layers arranged onthe substrates, a sealing layer is formed by utilizing the match of the barrier layers on the substrates when the motherboard is formed in buckling the substrates, the buckled substrates are sealed to effectively prevent grinding liquid from entering the substrates when the substrates are ground, and the process steps in buckling the box are reduced.

Description

Technical field [0001] The embodiments of the present invention relate to the field of liquid crystal display technology, and in particular to a method for manufacturing a motherboard, a substrate, and a substrate of a liquid crystal display panel. Background technique [0002] With the development of liquid crystal display technology, liquid crystal display panels have been widely used in various industries. At the same time, users have higher and higher requirements for liquid crystal display panels, and the development of light and thin liquid crystal display panels is one of the important development trends. [0003] At present, in order to meet the market's demand for ultra-thin and short-sized LCD panels, the LCD panel is usually made lighter and thinner by grinding based on the thickness of the original LCD panel's motherboard. figure 1 It is a schematic diagram of applying frame glue on the substrate when the glass substrate is boxed in the prior art. Such as figure 1 As sh...

Problems solved by technology

[0004] The inventor found in the process of realizing the present invention that: when the motherboard of the existing liquid crystal display panel adopts a frame glue sealing method to protect the liquid crystal layer when the box is assembled, the frame glue occupies a large area, so that the edge utilization rate of the glass substrate is relatively low. Low, and when the box is sealed with frame glue, there are many process steps and complicated process, the sealing quality is unstable, which affects the sealing effect. When grinding the motherboard of the liquid crystal display panel behind the box, it may still be due to the frame glue Poor sealing leads to the entry of abrasive liquid, which damages the liquid crystal molecules in the liquid crystal layer and affects the image display effect of the mother board of the liquid crystal display panel
