PURPOSE: A current driving circuit of a plasma display panel and an apparatus thereof are provided to make a generated current flow in a plurality of current-driven ICs of a display panel uniformly and to output a driving current to the display panel with a fixed density through the current-driven IC and to perform gamma correction to the driving currents. CONSTITUTION: According to the current driving apparatus, current driving ICs(1,2,3,4) and a reference current source(5) are connected between a high potential voltage(VDD) and a low potential voltage(GND) in cascade. Thus, a reference resistor(Rr) included in each current driving IC and the reference current source are connected each other in cascade so that an external reference current(IRef) flows through the reference resistor of each current driving IC from the high potential voltage(VDD).
