A sealant (9), a method for producing bezel-less liquid crystal display, and a bezel-less liquid crystal display produced by the same. The sealant (9) comprises: an azopyridine derivative represented by the structural formula (1); one or more of polyvinyl alcohol and ethylene-vinyl acetate copolymer; and a solvent, wherein m in the structural formula (1) is an integer of 8-20; and a mass ratio of the azopyridine derivative to the one or more of polyvinyl alcohol and ethylene-vinyl acetate copolymer is 1/99-15/85. A color filter substrate (6) and an array substrate (7) of a liquid crystal display are bound under the irradiation of ultraviolet light by using the photothermal effect and the binding property of a mixture of an azopyridine derivative and one or more of polyvinyl alcohol and ethylene-vinyl acetate copolymer, while the bezel of the liquid crystal display panel is not occupied, so as to obtain a bezel-less liquid crystal display.
