Estimating the term…
The invention discloses a frame-sealing agent, a display panel and a display device. The frame-sealing agent comprises an acrylic resin, an epoxy resin, a thermal curing agent and an ultraviolet photoinitiator, wherein the frame-sealing agent further comprises a compound which decomposes to produce a gas under a condition of light irradiation, heating or high temperature. In the invention, by providing a compound that decomposes to produce a gas under a condition of light irradiation, heating or high temperature, when the frame-sealing agent is cured, the compound decomposes to produce a gas with the effect of light irradiation, heating or high temperature. The light leak of the display screen at the position of backlight is obstructed by the gas. Additionally, the pressure of the gas can retard the diffusion of liquid crystal molecules, so that the contamination of the liquid crystal caused by the too early contact between the liquid crystal and the frame-sealing agent and the relevant display badness are avoided.
A display panel comprising a first substrate, a second substrate, and a frame-sealing agent cured between the first substrate and the second substrate, wherein the frame-sealing agent comprises an acrylic resin, an epoxy resin, a thermal curing agent, an ultraviolet photoinitiator, a silver halide wherein the halogen is Cl, Br or I, and at least one selected from the group consisting of ammonium carbonate, potassium permanganate, potassium chlorate and ethylbenzene.
