Abstract
A coating composition for forming a low-refractive-index layer includes a first fluorine compound represented by Formula 1 below, (CH2═CR1COO)2Rf Formula 1 and a reactive silicon compound, a (meth)acrylate compound, a polymerization initiator, and a solvent. The first fluorine compound represented by Formula 1, the reactive silicon compound, the (meth)acrylate compound, the polymerization initiator, and the solvent may each be different from one another, and in Formula 1, Rf may be a C1-19 perfluoro group, and R1 may be a hydrogen atom or a methyl group.
