A lead-free front dielectric composition is provided to be environment-friendly by not comprising lead component and bismuth component which are harmful to the human body, to suppress yellowing, and to lower driving voltage of a display device. A lead-free front dielectric composition for a display device comprises SiO2 10-20 weight%, B2O3 35-53 weight%, and Al2O3 10-20 weight%; first oxides 15-40 weight% including a mixture of at least two kinds selected from the group consisting of ZnO, BaO and SrO; second oxides 10-20 weight% containing a mixture of Li2O and K2O; and third oxides 0.1-3 weight% selected from the group consisting of Co3O4, NiO, MnO, CuO and their mixture.
