PURPOSE: A high quality plasma display panel which includes a blue phosphor composition is provided to accomplish high brightness and high color reproduction range by using blue phosphor compositions which displays high color purity and strong light emission rate. CONSTITUTION: A high quality plasma display panel which includes blue phosphor composition includes a blue phosphor composition which is represented by the following chemical formula: (aSr, bCa, cBa, dMg) 2 (a'B, b'Si, c'Al, d'Ge, e'In, f'Ga) 5O 9 (a''Cl, b''F, c''Br, d''I) :a'''Eu, B'''Ce, C'''Tm, D'''Yb, E'''Pr, F'''Sm, G'''Sn, H'''Pb, I'''Mn. In the chemical formula, 0.5 Δ a + b + c+ d Δ 0.9999, a + b + c+ d + a''' + b''' + c''' + d''' + e''' + f''' + g''' + h''' + i''' = 1, a' + b' + c' + d' + e' + f' = 1, a'' + b'' + c'' + d'' = 1, 0.8 < a' Δ 1, 0.5 Δ a'' Δ 1, and 0.0001 Δ a''' Δ 0.5.
