Claim 8:
9. A driving method of a light emitting display device comprising a display panel including a subpixel comprising an organic light emitting diode having an anode electrode connected to a first power line and a cathode electrode, a capacitor configured to store a data voltage and including a first electrode and a second electrode, and a driving transistor having a first electrode connected to the cathode electrode of the organic light emitting diode, a gate electrode connected to the first electrode of the capacitor, and a second electrode connected to the second electrode of the capacitor and a second power line, and a driver configured to drive the display panel, the driving method comprising:
applying an initialization voltage to the second power line; and
turning on the driving transistor such that the initialization voltage is applied to a node at which the cathode electrode of the organic light emitting diode and the first electrode of the driving transistor are interconnected via the second electrode of the driving transistor.
