    Abstract: A method of driving a display panel in an organic light-emitting display device is provided. The method determines whether a single color image is displayed on the display panel or a multiple color image is displayed on the display panel, applies an initialization voltage, for initializing an anode of an organic light-emitting element included in a non-light-emitting pixel, to the anode of the organic light-emitting element included in the non-light-emitting pixel when the multiple color image is displayed on the display panel, and applies a lateral leakage prevention voltage that is higher than the initialization voltage to an anode of an organic light-emitting element included in an adjacent non-light-emitting pixel that is located within a reference distance from a light-emitting pixel when the single color image is displayed on the display panel.

    Abstract: An organic light-emitting display device includes a plurality of anodes and an auxiliary electrode disposed on the substrate. The auxiliary electrode is separated from the plurality of the anodes. The organic light-emitting display device further includes an organic layer disposed on the plurality of the anodes, an opening penetrating the organic layer to expose the auxiliary electrode, and a cathode disposed on the organic layer and the exposed auxiliary electrode. The cathode is electrically connected to the auxiliary electrode. The opening has a first width at a proximal end and a second width at a distal end. The distal end is closer to the auxiliary electrode than the proximal end. The first width is smaller than the second width.
