  • Patent number: 10141538
    Abstract: A sealant, a display panel and a display device are provided. The sealant includes: a main body material and a reflective material distributed in the main body material. In the case that the display device adopts the sealant, due to the scattering effect of the reflective material, the light incident onto the sealant is scattered by the reflective material and the light scattered by the reflective material cannot be continuously propagated along an original total reflection propagation direction, so that the light, which is originally totally reflected, emerges from the display panel, and thus the light extraction efficiency of the display panel is improved.
