PURPOSE: An environment-friendly photopolymerizable composition is provided to form an optical sheet of a back light unit with excellent luminance characteristic as a non-halogen compound showing high refractive index. CONSTITUTION: A photopolymerizable composition includes a bisphenol diacrylate-based derivative represented by chemical formula 1 or 2. In chemical formulae, a, b and c are the same or different, and are an integer of 0-15; z is an integer of 0-15; m, x and y are the same or different, and are an integer of 0-15; when a, b and c are not 0, m, x and y are not 0; and R and R^2 - R^11 are hydrogen atom or C1-15 alkyl group, C6-30 aromatic ring, OH, SH or C1-15 alkyl-substituted amino group. |
