PROBLEM TO BE SOLVED: To obtain a substrate glass for a plasma display capable of giving a high luminance color image even of NiO or CoO is added so as to obtain high contrast. SOLUTION: The glass contains 0.1-10 wt.% Nd2 O3 and is a compsn. consisting of, by weight, 50-75% SiO2 , 0.5-15% Al2 O3 , 10-27% MgO+CaO+SrO+ BaO, 7-15% Li2 O+Na2 O+K2 O, 0-9% ZrO2 , 0.5% TiO2 , 0-1% Cl, 0-1% SO3 and 0.1-10% Nd2 O3 . |
