Abstract
A polythiol composition according to exemplary embodiments includes a first polythiol compound which provides a maximum peak in a high performance liquid chromatography (HPLC) analysis graph obtained at a wavelength of 230 nm, and a second polythiol compound having a molecular weight greater than that of the first polythiol compound and represented by CHS. A ratio of a peak area of the second polythiol compound to a peak area of the first polythiol compound, which are measured through the HPLC analysis graph at the wavelength of 230 nm, is 0.05 to 5.0%.
