1. A display device comprising:
a display panel including a plurality of pixels and divided into a first display area which operates at a first operating frequency and a second display area which operates at a second operating frequency; and
a voltage generator, which provides an anode initialization voltage to the plurality of pixels,
wherein, in an operation mode, the anode initialization voltage has a first voltage level when pixels corresponding to the first display area among the plurality of pixels are driven, and
wherein, in the operation mode, the anode initialization voltage has a second voltage level different from the first voltage level when pixels corresponding to the second display area among the plurality of pixels are driven.
