The present invention relates to a resin composition for surface sealing of an organic EL element, comprising: an alicyclic compound (A) having an oxetanyl group or an epoxy group; The cyclic compound (B) that satisfies the following conditions; the condition of the cyclic compound (B): the ring in the cyclic compound (B) is an aliphatic ring or a heterocyclic ring, and the ring is an aliphatic ring In this case, the cyclic compound is a compound having a different structure from the compound used as the alicyclic compound (A). The resin composition for surface sealing of an organic EL element of the present invention has an excellent liquid refractive index, and by curing the resin composition with energy rays such as light or heat, excellent visible light transmittance and light resistance, high Tg, Cured product with low curing shrinkage and water vapor transmission rate, so it is especially suitable as surface sealing material for organic EL elements. |
