Disclosed are a radiation curable resin having an extremely low possibility of contaminating liquid crystals, and a liquid crystal sealing material using such a radiation curable resin. Specifically disclosed is a liquid crystal sealing material characterized by containing a radiation curable resin (a) represented by the general formula (1) below, a photopolymerization initiator (b) and a filler (c) having an average particle diameter of not more than 3 m. (In the formula (1), R1 represents a hydrogen atom or a methyl group; R2 may be the same or different and respectively represent a hydrogen atom, a halogen atom, a hydroxyl group, a monovalent straight chain, branched or cyclic alkyl group having 1-10 carbon atoms or an alkoxy group having 1-10 carbon atoms; m represents an integer of 1-4; R3 represents a hydrogen atom or a methyl group; R4 represents a straight chain, branched or cyclic alkyl group having 1-10 carbon atoms; l represents a range of positive numbers from 1 to 5; and the repeating unit number
