PURPOSE: A photo absorbing compound and a visible ray-based photo-sensitive composition including the same are provided to improve the photo stability of the composition by selectively absorbing light in a wavelength of 400-600nm. CONSTITUTION: A photo absorbing compound is represented by chemical formula 1. In the chemical formula 1, the R1 is hydrogen, halogen, nitro, sulfoxide, benzene, or naphthalene group. The R2 is carbon, oxygen, nitrogen, sulfur, methyl carbon, or dimethyl carbon group. The R3 is oxygen or sulfur. The R4 and the R5 are respectively hydrogen or alkyl group. The n is 1 to 2. A photo-sensitive composition includes the compound and further includes a resin, a binder, a solvent, and a catalyst. |
