The present disclosure provides a packaging adhesive, a packaging method, a display panel, and a display device. The packaging adhesive includes a frit, an organic solvent, and a material with a thermal expansion coefficient larger than that of the frit. Using the packaging adhesive provided by the present disclosure, the thermal expansion coefficient of the packaging adhesive from which the organic solvent is removed may be enhanced by doping the material with a thermal expansion coefficient larger than that of the frit into existing glass cement, so that in a packaging process using laser radiation, an expansion volume of the packaging adhesive when heated is increased. In this way, a gap between the packaging adhesive and an array substrate is effectively reduced, and a packaging effect is improved.
