Zusammenfassung:	A driving device of a display apparatus and a display apparatus including the same are provided to enhance driving voltages in initial operation by implementing a temperature control voltage generator at a feedback stage of a DC/DC converter. A driving device of a display apparatus includes a DC/DC(Direct Current) converter and a driving voltage generator(700). The DC/DC converter, including a feedback stage(FB), generates driving voltages. The driving voltage generator includes a temperature sensor, an OP AMP(OPerational AMPlifier), and a temperature control voltage generator(710). The temperature control voltage generator receives voltage from the temperature sensor and generates output voltages through an output stage of the OP AMP. An output voltage of the temperature control voltage generator is supplied to the feedback stage of the DC/DC converter.
