A plasma display apparatus is disclosed. The plasma display apparatus includes a scan electrode and a sustain electrode positioned parallel to each other, and an address electrode positioned to intersect the scan electrode and the sustain electrode. A reset signal is supplied to the scan electrode, and a first bias signal is supplied to the address electrode to overlap the reset signal. A voltage magnitude of the first bias signal satisfies the following Equation: 0.15 g≦ΔV≦0.6 g, where ΔV is a magnitude of a highest voltage of the first bias signal in unit of volt, and g is an interval between the scan electrode and the sustain electrode in unit of μm.
