1. A display device, comprising:
a display panel including a plurality of pixels;
a data driver configured to apply a plurality of data voltages generated based on input image data to the pixels;
an initialization voltage generator configured to generate an initialization voltage that initializes a light emitting element included in each of the pixels;
a timing controller configured to generate a constant current control signal based on a load of the input image data; and
a constant current generator configured to generate and transmit a constant current to the initialization voltage generator in response to the constant current control signal,
wherein the timing controller is configured to generate the constant current control signal corresponding to a set constant current value determined based on the load, and
wherein the constant current generator is configured to generate the constant current having the set constant current value.
