Abstract: A driving device includes an output timing controller which controls an output timing of a first driving voltage and a second driving voltage respectively generated from a first voltage generator and a second voltage generator. A third driving voltage output from the output timing controller is provided to a first data driver and a second data driver, and also provided to a gamma voltage generator to generate a plurality of gamma voltages. Accordingly, a reverse electric potential between the third driving voltage and the gamma voltages is prevented from being generated in the first and second data drivers, therefore, preventing the first and second data drivers from being damaged.
