Abstract: A coating composition may include a glass frit including Phosphorus Oxide (P2O5), Silicon Oxide (SiO2), Boron Oxide (B2O3), a group I-based metal oxide, Barium Oxide (BaO), Sodium Fluoride (NaF), Titanium Oxide (TiO2), Stannous Oxide (SnO), Zinc Oxide (ZnO), and an adhesion enhancement component. The P2O5 may be included by about 40 wt % to about 55 wt % based on a total weight of the glass frit. The SiO2 may be included by about 5 wt % to about 15 wt % based on the total weight of the glass frit. The B2O3 may be included by about 5 wt % to about 10 wt % based on the total weight of the glass frit. The group I-based metal oxide may be included by about 3 wt % to about 10 wt % based on the total weight of the glass frit. The ZnO may be included by about 10 wt % to about 25 wt % based on the total weight of the glass frit, and the TiO2 may be included by about 0.1 wt % to about 5 wt % based on the total weight of the glass frit.
