Patent ID: 8475912

Claim:
A coating composition for forming a low-refractive-index layer, the composition comprising: about 70 to about 95 parts by weight of a fluorine compound including a first fluorine compound represented by Formula 1 below; (CH 2 ═CR 1 COO) 2 R f Formula 1 about 0.1 to about 15 parts by weight of a reactive silicon compound; about 1 to about 20 parts by weight of a (meth)acrylate compound; about 0.1 to about 10 parts by weight of a polymerization initiator; and a solvent, wherein: the first fluorine compound represented by Formula 1, the reactive silicon compound, the (meth)acrylate compound, the polymerization initiator, and the solvent are each different from one another, in Formula 1, R 1 is a hydrogen atom or a methyl group and the R f in Formula 1 is a moiety represented by one of Formulae 2(a)-(e) below: in Formula 2(a)-(e), R f1 is a linear C 1-10 perfluoro group, and R f2 , R f3 , R f4 , and R f5 are each independently a linear C 1-14 perfluoro group, and all parts by weight are based on 100 parts by weight of a total solid content of the composition.
