a light emitting layer disposed on the first electrode in correspondence to the light emitting area; and
a second electrode disposed on the light emitting layer.

4. The display device of claim 1 , wherein the display panel comprises:
a base substrate;
a circuit element layer disposed on the base substrate;
a first electrode disposed on the circuit element layer in correspondence to the light emitting area;
a pixel defining film disposed on the circuit element layer to define the light emitting area and the transmitting area;
a light emitting layer disposed on the first electrode in correspondence to the light emitting area; and
a second electrode disposed on the light emitting layer, wherein the second electrode does not overlap the transmitting area.

5. The display device of claim 1 , wherein
the first display area comprises a first driving area, and the second display area comprises a second driving area and a third driving area,
the first driving area comprises a first scan driver which drives a plurality of first scan lines, and first pixels respectively connected to the plurality of first scan lines,

8. The display device of claim 7 , wherein
the driving controller outputs the first to third scan control signals in a way such that at least one of the first to third scan drivers is activated.

9. The display device of claim 5 , further comprising:
a second driving circuit,
wherein the first driving circuit drives the first display area to display an image in the first display area, and
the second driving circuit drives the second display area to display an image in the second display area.

10. The display device of claim 9 , wherein
the first driving circuit comprises:
a first driving controller which outputs a first data signal and a first data control signal; and
a first data driver which drives first data lines in response to the first data signal and the first data control signal, and
the second driving circuit comprises:
a second driving controller which outputs a second data signal and a second data control signal; and
a second data driver which drives second data lines and third data lines in response to the second data signal and the second data control signal,
wherein each of the first pixels is connected to a corresponding one of the first data lines,
each of the second pixels is connected to a corresponding one of the second data lines, and
each of the third pixels is connected to a corresponding one of the third data lines.

11. The display device of claim 10 , wherein
