PROBLEM TO BE SOLVED: To provide a plasma display device all positively charged, equipped with green-color phosphor with little absorption of or reaction to water, carbon monoxide, carbon dioxide or carbon hydride. SOLUTION: In the plasma display device, a green-color phosphor layer consisting of at least one kind selected from: general formula M<SB>1-a</SB>(Ga<SB>1-x</SB>Al<SB>x</SB>)<SB>2</SB>O<SB>4</SB>: Mn<SB>a</SB>(provided, M is a kind out of Zn, Mg, Ca, and Sr); general formula (Y<SB>1-a-y</SB>Gd<SB>a</SB>)(Ga<SB>1-x</SB>Al<SB>x</SB>)<SB>3</SB>(BO<SB>3</SB>)<SB>4</SB>:Tb<SB>y</SB>; general formula (Y<SB>1-a-y</SB>Gd<SB>a</SB>)(Ga<SB>1-x</SB>Al<SB>x</SB>)<SB>3</SB>(BO<SB>3</SB>)4:Ce<SB>y</SB>, Tb<SB>y</SB>; general formula (Y<SB>1-a-y</SB>Gd<SB>a</SB>)BO<SB>3</SB>:Tb<SB>y</SB>; or general formula (Y<SB>1-a-y</SB>Gd<SB>a</SB>)<SB>3</SB>(Ga<SB>1-x</SB>Al<SB>x</SB>)<SB>5</SB>O<SB>12</SB>:Tb<SB>y</SB>.
