Provided are a display device capable of preventing burning by suppressing occurrence of a VCOM shift which occurs when a liquid crystal panel is driven for a long period of time, and a drive method thereof. Since a source output voltage corresponding to each of tone levels from a tone value 0 to a tone value 224 agrees with a flicker regulation voltage, a shift amount from the flicker regulation voltage is set to 0 mV, and a source output voltage corresponding to a tone value 255 is obtained by further adding +40 mV as a shift amount to 4.05 V which is the flicker regulation voltage. In such a manner, a source output voltage, increased at a high tone level and in the vicinity thereof, is applied to source bus lines SL 1 to SLm and written into each liquid crystal capacitance Ccl. |
