description The present invention relates to a sealing agent for a display which can be applied to a flexible display or a display having a curved shape. Particularly, the present invention relates to a sealing agent for a display including a compound having a specific structure in the molecule. The sealing agent for a display shows excellent adhesion strength to an adherent and has flexibility compatible with low water permeability, and thus is useful as a sealing agent particularly for a display requiring adhesiveness to an organic film, a flexible display or a display having a curved shape. The sealing agent for a display includes (A) an urethane (meth)acrylate obtained by reacting (a) a polyol, (b) an organic polyisocyanate and (c) a hydroxyl group-containing (meth)acrylate, and includes, as ingredient (a), a dimeric diol or a polyester diol formed from a dimeric diol and a polyhydric carboxylic acid.
