1. A display device comprising:
a display panel, which receives a driving voltage and an initialization voltage;
a power manager, which provides the driving voltage to the display panel; and
a voltage generator, which receives a feedback driving voltage from the display panel and generates the initialization voltage based on the feedback driving voltage,
wherein the voltage generator increases the initialization voltage when the feedback driving voltage increases and decreases the initialization voltage when the feedback driving voltage decreases,
wherein the feedback driving voltage is a voltage that is fed back to the voltage generator after the driving voltage supplied from the power manager passes through the display panel,
wherein the display panel includes a plurality of pixels,
wherein at least one of the plurality of pixels includes a light emitting element including a first electrode and a second electrode,
the power manager provides the driving voltage to the second electrode of the light emitting element, and
the voltage generator receives the feedback driving voltage from the second electrode of the light emitting element.
