PROBLEM TO BE SOLVED: To incorporate no lead into a glass layer covering an electrode at a front substrate or the like in a plasma display device. SOLUTION: The glass for covering electrode is essentially composed of, by mol% based on the following oxides, 15 to 65% B<SB>2</SB>O<SB>3</SB>, 2 to 30% SiO<SB>2</SB>, 5 to 45% MgO+CaO+SrO+BaO, 2 to 25% Li<SB>2</SB>O+Na<SB>2</SB>O+K<SB>2</SB>O, 0 to 30% Al<SB>2</SB>O<SB>3</SB>, 0.1 to 15% Bi<SB>2</SB>O<SB>3</SB>and 0 to 15% P<SB>2</SB>O<SB>5</SB>, and in which, in the case ZnO is comprised, its content is <5 mol%, and does not comprise PbO. In the plasma display device, an electrode formed at a front substrate or a rear substrate is covered with glass for covering electrode. COPYRIGHT: (C)2007,JPO&INPIT
