More Information
Summary:This sealing agent for a display element according to the present invention comprises (A) an alicyclic epoxy compound having a cycloalkene oxide structure, (B) an oxetane compound, (C) an aliphatic epoxy compound (being different from said alicyclic epoxy compound), and (D) a cationic polymerization initiator, wherein the alicyclic epoxy compound (A), the oxetane compound (B), and the aliphatic epoxy compound (C) each have a weight-average molecular weight of 180 or more, and an oxygen atom content represented by formula (1) of 15% or more. (1): Oxygen atom content (%) = the total mass of oxygen atoms per molecule/weight-average molecular weight × 100
