Abstract: Embodiments of the present application disclose an encapsulation material, a display panel, and an encapsulation method. By mass percentage, the encapsulation material includes a main resin, 20%-50%; a dilute monomer, 20%-50%; a stabilizer, 0.01%-2%; a microgel, 1%-10%; a chain transfer agent, 0.01%-5%; and an initiator in a remaining percentage balance. The encapsulation material can be cured under action of UV light to form an encapsulation layer, anti-aging performance of the encapsulation layer can be improved, and toughness can be enhanced to reduce warpage. The microgel structure can enhance the toughness of the encapsulation layer and make it have excellent corrosion resistance. Ester activated vinyl sulfonate is used as the chain transfer agent to make an average chain length in a polymer network shorter, reduce a risk of shrinkage cracks appearing during curing, and enhance the toughness of the encapsulation layer after the curing.
