    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: A backlight unit includes a light conversion member; a light guide plate including a light exit surface, a rear surface facing the light exiting surface, and connection surfaces including a first surface and a second surface facing each other to connect the light exit surface and the rear surface; a reflective member; and a light source emitting a first color light incident to the first surface and a portion of the first color light reaches the second surface on which the reflective member is disposed to specularly reflect the portion of the first color light. The light conversion member is disposed on the light exit surface, receives the first color light from the light guide plate, and emits a second color light different from the first color light.
