Claim 0:
1. An optical resin comprising:
in the optical resin disposed on a surface of a molding member sealing a light emitting chip or a surface of a light emitting device having a light emitting chip,
oligomers, monomers and additives;
wherein the monomer include acrylate having an epoxy group without using acrylate having a hydroxyl group,
the monomer includes IBOA (Iso-bornyl Acrylate), two or more dilution monomers, and glycidyl methacrylate (GMA),
wherein the additive includes a photoinitiator of ultraviolet wavelength and an amine-based light stabilizer,
wherein in the oligomer and the monomer, a content of the oligomer is 20-25%, a content of the IBOA is 40-50%, a content of the two or more dilution monomers is 10-20%, and a content of the glycidyl methacrylate is 10 to 15%,
wherein the optical resin is a curable transparent resin, and
wherein a content of the monomer in the optical resin is three times higher than the content of the oligomer.
