There is provided a device for driving a light-emitting display panel in which output limiter means is added to a DC-DC converter which associates a boosting operation. In the drive device, even though a forward voltage of a monitor element increases to operates the limiter means, predetermined display quality can be assured without considerably disrupting a color balance. On a display panel, a display region in which display pixels of R, G, and B are arranged and an arrangement region for monitor elements which monitor forward voltages of R, G, and B are formed. Output voltages obtained by the respective DC-DC converters are controlled based on the forward voltages obtained by the monitor elements. An output limiter is constituted by zener diodes to prevent converter output values from being excessive by increases in forward voltages from the monitor elements due to aging. Limiter values obtained by the zener diodes are set at different levels. The drive device is designed to preventacolor balance from being considerably disrupted even though a limiter operation is executed due to aging.
