Abstract
An isocyanurate compound for forming an organic anti-reflective coating layer, which has superior stability and etch rate at a high temperature, and which has a high refractive index, is represented by following Formula 1. In Formula 1, R is independently a hydrogen atom or a methyl group, Ris independently a chain type or ring type saturated or unsaturated hydrocarbyl group of 1 to 15 carbon atoms containing 0 to 6 of hetero atoms, and Rindependently a chain type or ring type saturated or unsaturated hydrocarbyl group of 1 to 15 carbon atoms containing 0 to 15 of hetero atoms, wherein, Rcan have at least two bonding parts, and in the case that Rhas at least two bonding parts, the rest parts except Rof the compounds represented by Formula 1 can connect to the Rto form a polymer structure.
