ABSTRACT:
There is provided a glass ceramic material for plasma display, in which glass fine grains (A) having a softening point of 570-640° C. are in 40-70 wt %, and glass fine grains (B) having a softening point of 480-540° C. are in 30-60 wt %, the glass ceramic material for plasma display being characterized in that the glass fine grains (A) comprise 2-12 wt % of SiO2, 50-58 wt % of B2O3, 10-20 wt % of Al2O3, 0-6 wt % of ZnO, 0-2.8 wt % of Li2O, and 10-22 wt % of at least one selected from MgO, CaO, SrO and BaO and that refractive index of the glass fine grains (A) is 1.53-1.56.
