Abstract

A display sealing material composition includes a photopolymerization initiator and a photocuring monomer, the photocuring monomer comprising: a monomer not having the aromatic hydrocarbon group; and a monomer having two or more substituted or unsubstituted phenyl groups. An organic protection layer obtained by curing the composition for a display sealing material has approximately 400 nm/min or less plasma etching rate being represented by formula 1 below and approximately 2 nm or less surface roughness.Plasma etching rate(nm/min)=(0−1)/  <Formula 1>wherein T0, T1, and M are set forth in the specification.
