PURPOSE: A scanning drive circuit for plasma display panel is provided to decrease a size of a hardware by using an address/display simultaneous driving method and relatively decreasing switches for a scanning drive. CONSTITUTION: Power switching circuits(SS1,...,SS6) output two electric potentials which are simultaneously used among a first voltage(V1), a second voltage(V2), a third voltage(V3), a fourth voltage(V4) and a ground voltage(Vg) according to a timing control signal of a controller. Each line switching circuit(SL11,SL12,SL21,SL22,...,D11,D12,D21,D22,...) is connected to an input terminal of corresponding scanning electrode lines(Y1,Y2,...,Yn) and outputs one scanning electrode line(Y1,Y2,...,Yn) corresponding to one electric potential between two electric potentials inputted from the power switching circuits(SS1,...,SS6).
