Abstract
The invention provides frame glue, a display panel and a manufacturing method of the display panel, the frame glue is applied to the display panel, and the frame glue comprises epoxy resin; the composite particle comprises a shell and a liquid curing agent, the shell is provided with an accommodating space, the liquid curing agent is accommodated in the accommodating space, the shell is made of a solid inert material, and the liquid curing agent can be subjected to curing reaction with the epoxy resin. The shell of the composite particles in the frame adhesive provided by the embodiment of the invention is made of the solid inert material, so that the shell is easy to break after being extruded in the manufacturing process of the display panel, and then the liquid curing agent in the shell flows out of the shell and is subjected to curing reaction with the epoxy resin, so that the UV curing rate is improved, and compared with the prior art, the cost is reduced. Therefore, more frame glue is subjected to curing reaction, pollution of the acrylic resin which is not completely cured to liquid crystals is reduced, and the problem that the frame glue pollutes the liquid crystals is solved.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a sealant, a display panel and a manufacturing method of the display panel. Background technique [0002] During the display panel manufacturing process, UV light curing is first performed, and some acrylic small molecules are developed and polymerized to survive the acrylic macromolecule, so that the frame glue is basically shaped and a certain adhesion is formed; the subsequent thermal curing process is carried out, and the thermal initiator causes the environmental Oxygen resin undergoes a polymerization reaction to form a polymer, and some unreacted acrylic small molecules will also undergo a polymerization reaction to form a polymer during the thermal process. This process produces a stronger adhesive force, making the two substrates of the display panel tight. tightly together. [0003] However, during the manufacturing process of the display panel, due to the s...
