Abstract

The invention discloses a composition, an ultraviolet absorption band, a liquid crystal display panel and a manufacturing method of the liquid crystal display panel. The composition comprises the following components in parts by weight: 30-70 parts of an ethylene-vinyl acetate copolymer and 30-70 parts of (E)-6(4-(4-hexane sulfonyl) phenylethenyl) phenoxy) hexane-1-alcohol. The ultraviolet absorption band is prepared from the composition. The liquid crystal display panel comprises the ultraviolet absorption band. The manufacturing method of the liquid crystal display panel comprises a coating step and a folding step. The composition is coated between a frame sealing adhesive and a display area and is used for absorbing ultraviolet light to be irradiated into the display area while curing the frame sealing adhesive, so that the distance a from the outer edge of a mask plate to the display area can be reduced; meanwhile, the distance b from the outer edge of the mask plate to the inner edge of the frame sealing adhesive can be reduced, so that the narrow-frame liquid crystal display panel can be manufactured.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a composition, an ultraviolet absorption tape, a liquid crystal display panel and a manufacturing method thereof. Background technique [0002] Narrow bezel liquid crystal display panels have become a research hotspot in the field of display due to their larger display screen, beautiful appearance and better user experience. [0003] Such as figure 1 As shown, a conventional liquid crystal display includes: a color filter substrate 1, a black matrix 2, a display area 3, an array substrate 4, a mask plate 5 and a sealant 6; the factors determining the width of the frame e of the liquid crystal display panel include: the mask plate The distance a from the outer edge to the display area, the distance b from the outer edge of the mask to the inner edge of the sealant, the width c of the sealant, and the cutting accuracy d. [0004] Among them, the frame sealant 6 is usually a ...
