1. A display device, comprising: a plurality of first pixels disposed in a first pixel area and initialized by a voltage of a first initialization power source; a plurality of second pixels disposed in a second pixel area and initialized by a voltage of a second initialization power source different from the first initialization power source; a data driver that supplies a data signal to a plurality of data lines connected to the first pixels and the second pixels; and a scan driver that supplies a scan signal to a plurality of scan lines connected to the first pixels and the second pixels, wherein a black data signal supplied from the data driver to the first pixels and a black data signal supplied from the data driver to the second pixels are set to a same voltage, wherein the first pixels comprise pixels of a first color and pixels of a second color, and wherein the voltage of the first initialization power source supplied to the pixels of the first color and the voltage of the first initialization power source supplied to the pixels of the second color are set to be different from each other, wherein the voltage of the first initialization power source supplied to the pixels of the first color and the voltage of the first initialization power source supplied to the pixels of the second color are set to be different from each other in response to a different temperature.
 
11. A method of driving a display device, comprising: initializing a light emitting element included in each of a plurality of first pixels disposed in a first pixel area while supplying a voltage of a first initialization power source; and initializing a light emitting element included in each of a plurality of second pixels disposed in a second pixel area while supplying a voltage of a second initialization power source different from the first initialization power source, wherein a voltage of a black data signal supplied to the first pixels and a voltage of a black data signal supplied to the second pixels are set to be the same wherein the first pixels comprise pixels of a first color and pixels of a second color, and wherein the voltage of the first initialization power source supplied to the pixels of the first color and the voltage of the first initialization power source supplied to the pixels of the second color are set to be different from each other, wherein the voltage of the first initialization power source supplied to the pixels of the first color and the voltage of the first initialization power source supplied to the pixels of the second color are set to be different from each other in response to a different temperature.
