A driving circuit is capable of displaying various gray level values. The driving circuit generates a data voltage, includes a first decoder adapted to output first decoding signals using upper bits of a digital data signal, a switch unit adapted to select a first reference voltage and a second reference voltage corresponding to first decoding signals, the second reference voltage being lower than the first reference voltage, where two first decoding signals select identical first and second reference voltages, a second decoder adapted to output second decoding signals using lower bits of the digital data signal, and voltage distribution units are adapted to receive and distribute the selected first and second reference voltages, where one voltage distribution unit includes a data voltage generation unit adapted to receive two second decoding signals to generate a data voltage.
