Provided are a phosphor used in a PDP, which is a compound represented by Formula 1 below and a PDP including a phosphor layer comprising the phosphor. <?in-line-formulae description="In-line Formulae" end="lead"?>(Y<SUB>1-x-y</SUB>Gd<SUB>x</SUB>Tb<SUB>y</SUB>)Al<SUB>r</SUB>Q<SUB>3-r</SUB>(BO<SUB>3</SUB>)<SUB>4 </SUB>Formula 1 <?in-line-formulae description="In-line Formulae" end="tail"?> where 0<x<=1, 0<y<=1, Q is Sc, In, or Ga, and 0<=r<3. When the phosphor is used to form a green phosphor layer of a PDP, the luminance saturation problem of a conventional green phosphor can be overcome. In addition, a PDP including a phosphor layer comprising the phosphor has a wider color reproduction range and no reduction in luminance according to the mixing ratio of each phosphor contained in the phosphor compared with a conventional phosphor used in a PDP. Therefore, a PDP including a phosphor layer comprising the phosphor can have far superior image qualities.
