An acryl-based compound of the present invention is represented by chemical formula 1. The acryl-based compound does not comprise a halogen element, and has a high refractive index greater than or equal to 1.65 of a refractive index. In chemical formula 1, R_1 and R_2 are each independently an alkylene group of 2 to 10 carbon atoms, an arylene group of 6 to 20 carbon atoms, an alkyl arylene group or an aryl alkylene group of 7 to 20 carbon atoms. Ar_1 is an aryl group of 6 to 10 carbon atoms. X_1 and X_2 are each independently -O- or -S-. Y_1 and Y_2 are each independently a hydrogen atom, -OH, -NH_2, or a (meth)acrylate group wherein R_3 is a hydrogen atom or a methyl group; X_3 is -O- or -N(R)-(R is a hydrogen atom or an alkyl group); and * exhibits a binding portion. At least one of Y_1 and Y2 is the (meth)acrylate group. An average value of n_1 and n_2 is each independently 1 to 4. |
