Display device, electronic device including the same, and method of driving the same

A display device comprising:

• a display panel comprising a first display area in which first pixels are disposed at a first density and a second display area in which second pixels are disposed at a second density lower than the first density, wherein each of the first pixels and the second pixels comprises a light-emitting element;
• a power supply circuit configured to supply a first anode initialization voltage to the light-emitting element included in each of the first pixels and supply a second anode initialization voltage to the light-emitting element included in each of the second pixels;
• and
• a timing controller configured to control the power supply circuit so that a voltage level of the second anode initialization voltage becomes greater than a voltage level of the first anode initialization voltage.
