Display device

The display device includes: a display panel including a plurality of pixels; a data driver applying a data signal to the display panel; the scanning driver comprises a plurality of scanning driving stages and sequentially applies scanning signals to the display panel; a light-emitting driver including a light-emitting driving stage and sequentially applying a light-emitting signal to the display panel; a controller that controls the scan driver, the light emission driver, and the data driver; and a power supply voltage generating section generating a power supply voltage including a high voltage and a low voltage, and supplying the high voltage of different magnitude or the low voltage of different magnitude to at least one of the plurality of scan driving stages and the light emitting driving stages. At this time, the power supply voltage generation unit generates a first high voltage, a first low voltage, a second high voltage smaller than the first high voltage, and a second low voltage larger than the fi
