A driving circuit capable of decreasing an error of a gray level voltage without affecting a voltage drop when a gray level signal of a D/A converter is generated in an analog switch, and an organic electroluminescence display using the same. The driving circuit includes first and second switch units to select respective first and second reference voltages to correspond to a data signal; a resistor including a plurality of resistor arrays to receive and distribute the first and second reference voltages by utilization of at least two resistances to generate a gray level voltage; a third switch unit to select one resistor array out of the plurality of arrays to correspond to the data signal and to transmit the first and second reference voltages to the selected resistor array; and a fourth switch unit to output the gray level voltage, generated by the resistor array, to correspond to the data signal.
