A display device includes a display panel, a power supply part which is located in the outside of the display panel and generates a power voltage for driving pixels, and a power voltage control part which receives a power voltage from the power supply part, divides the power voltage to generate a partial voltage, compares the partial voltage with a predetermined reference voltage to output a comparison result signal, and controls the output of the power supply part to make the partial voltage equal to the reference voltage based on the comparison result signal. So, the display device can supply a power voltage with a constant voltage level to the display panel. |
