5. The display panel of claim 1 , further comprising:
a first potential supply electrode disposed in the bezel area to supply a first potential to the pixel array of the active area;
a second potential supply electrode disposed in the bezel area to supply a second potential lower than the first potential to the pixel array of the active area; and
first potential supply lines connected to the first potential supply electrode, extended to the active area, and disposed to avoid the at least one module area.
6. The display panel of claim 5 , further comprising:
another first potential supply electrode disposed in the bezel area to supply the first potential to the pixel array.
7. The display panel of claim 6 , wherein both ends of the first potential supply electrode and the other first potential supply electrode are connected by link lines disposed in the bezel area.
8. The display panel of claim 1 , further comprising:
shift registers of a gate driver disposed in the bezel area positioned on both sides of the active area to generate a gate signal to be supplied to the pixel array.
9. The display panel of claim 1 , wherein one of a camera, a speaker or a sensor is disposed on a surface of the display panel by overlapping the at least one module area.
10. The display panel of claim 1 , further comprising:
gate lines and data lines disposed in the active area to supply a gate signal and a data signal to the pixel array;
wherein the gate lines and the data lines are disposed to avoid the at least one module area.
11. The display panel of claim 1 , wherein the at least one module area includes only the at least one insulation layer between the adjacent pixels of the pixel array.
12. The display panel of claim 1 , the at least one insulation layer is located on a whole area of the at least one module area.
13. The display panel of claim 1 , wherein the second planarizing film is directly on the connection electrode, and continuously disposed in the light-transmissive area and the adjacent pixels of the pixel array.
14. A display apparatus comprising:
a display panel having an active area including at least one module area; and
a camera module disposed on the at least one module area,
wherein the active area comprises a pixel array,
wherein each pixel in the pixel array includes an organic light emitting diode, a thin film transistor, and a connection electrode connecting the organic light emitting diode to the thin film transistor,
wherein the at least one module area is configured to have a light-transmissive area including at least one insulation layer between adjacent pixels of the pixel array,
wherein the at least one insulation layer comprises a first planarizing film disposed between the thin film transistor and the connection electrode,
wherein the first planarizing film is disposed in the light-transmissive area and the adjacent pixels of the pixel array,
wherein the organic light emitting diode includes an anode electrode, an organic light emitting structure, and a cathode electrode sequentially stacked on the at least one insulation layer,
wherein the cathode electrode is not positioned in the at least one module area.
15. The display apparatus of claim 14 , wherein the anode electrode is connected to the thin film transistor via the connection electrode.
16. The display apparatus of claim 14 , wherein the cathode electrode covers in the entire region of the active area excluding the at least one module area.
17. The display apparatus of claim 16 , further comprising:
an encapsulation layer on the cathode electrode,
wherein the encapsulation layer is disposed closer to the cathode electrode than to the anode electrode.
18. The display apparatus of claim 14 , wherein the cathode electrode is formed of magnesium, calcium, aluminum, silver, or an alloy thereof.
