Problems solved by technology

[0006] However, on the one hand, the current black matrix is ​​generally made of resin, and the resin material itself has the problem of easy water absorption. Therefore, in the long-term use of the liquid crystal panel, the moisture absorbed by the resin material from the environment will easily cause liquid crystal Corrosion of the metal structure in the panel, so designing the black matrix 12 too long will obviously further aggravate the risk of corrosion, resulting in a decrease in the reliability of the liquid crystal pa

Abstract

The invention discloses a liquid crystal display panel and a manufacture method thereof. The liquid crystal display panel comprises an active element array substrate and a colorful filtering substrate, wherein the active element array substrate and the colorful filtering substrate are connected through frame sealing glue. The active element array substrate comprises a base, a public electrode wire and a plurality of film transistors. The colorful filtering substrate comprises a black matrix. The liquid crystal display panel comprises a display area and a frame area surrounding the display area. The active element array substrate further comprises a light absorbing layer with light absorbing property. The light absorbing layer is arranged inside the frame area and located between the base and a metal structure, closest to the base, in the frame area. The liquid crystal display panel can greatly reduce frame light leakage of the liquid crystal display panel on the premise that the black matrix is not lengthened so that the outer edge of the black matrix is aligned to the outer edge of the base.

Description

technical field [0001] The invention relates to a liquid crystal panel, in particular to a liquid crystal panel and a manufacturing method of the liquid crystal panel. Background technique [0002] A liquid crystal display generally includes a liquid crystal panel and a backlight module. The liquid crystal panel usually includes an active element array substrate, a color filter substrate and a liquid crystal layer between the two. [0003] A liquid crystal panel usually has a display area and a frame area surrounding the display area. figure 1 Shown is a schematic cross-sectional view of the frame area on one side of the liquid crystal panel. Such as figure 1 As shown, a color filter substrate 1 includes a base 11, a plurality of color filter units (not shown) disposed on the base 11 and a black matrix 12, the black matrix 12 is actually in the display area and There are distributions in the frame area. The black matrix located in the display area is mainly used to isolat...
