The present invention provides a sealing agent for liquid crystal dropping methods, which has excellent photocurability and is capable of suppressing liquid crystal contamination. The present invention also provides a vertically conducting material and a liquid crystal display element, each of which is produced using the sealing agent for liquid crystal dropping methods. The present invention is a sealing agent for liquid crystal dropping methods, which contains a curable resin and a photopolymerization initiator, and wherein the photopolymerization initiator contains a compound represented by formula (1) and an oxime ester compound so that the weight ratio of the compound represented by formula (1) to the oxime ester compound is from 1:3 to 1:100. In formula (1), each of R1 and R2 represents a hydrogen atom or an -NR3 2 group, and R1 and/or R2 represents an -NR3 2 group; and each R3 represents a hydrogen atom or an alkyl group having 1-4 carbon atoms. In this connection, the R3 moieties may be the same as or different from each other.
