1. A display device comprising:
a display panel including a pixel configured to receive a driving voltage;
a voltage generator configured to generate the driving voltage and to determine a voltage level of the driving voltage based on a voltage control signal; and
a driving controller configured to control driving of the display panel,
wherein the driving controller includes:
a current compensator configured to calculate a load based on a previous image data and to output compensation image data having a target luminance by compensating for a current image data based on the load, and
wherein the driving controller is configured to:
turn on the current compensator in a normal mode such that an image is displayed with the target luminance, and
turn off the current compensator in a setting mode such that an image corresponding to the current image data is displayed with a given reference luminance.
