Abstract: A display device includes a substrate including a display area including pixels, a pad area comprising pads and located adjacent to the display area and a side wiring area located adjacent to the pad area; and a printed circuit film attached to the pad area located on a back surface of the first substrate. The plurality of pads include first pads that electrically connect the printed circuit film to the pixels and at least one second pad disposed between adjacent ones of the first pads. The display device further includes at least one connection portion that electrically connects a first pad of the first pads and the at least one second pad to each other. Each of the first pads includes a first-first pad located on a front surface of the first substrate and a first-second pad located on the back surface of the first substrate.

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.
