a second mirror layer including at least one selected from the group consisting of indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide, and indium oxide.

4. The display device of claim 1 , wherein the sub-pixel includes first through third sub-pixels that emit different color lights from each other; and
wherein the transparent window is substantially collinear with one of the first through third sub-pixels.

5. The display device of claim 4 , wherein the transparent window is substantially collinear with biggest one of the first through third sub-pixels.

6. The display device of claim 1 , wherein the sub-pixel includes first through third sub-pixels that emit different color lights from each other; and
wherein the transparent window includes first through third transparent windows that are substantially collinear with the first through third sub-pixels, respectively.

7. The display device of claim 1 , wherein a ratio of a size of the transparent window to a size of the pixel ranges from about 3% to about 40%.

8. The display device of claim 1 , wherein the camera unit further includes:
a supporting member surrounding the camera module.

9. The display device of claim 1 , wherein the camera unit further includes:
a moving member connected to the camera module, the moving member configured to move the camera module.

10. The display device of claim 1 , wherein the display unit is disposed on the minor member.

11. The display device of claim 1 , wherein the encapsulation unit includes:
an encapsulation layer including a first organic layer disposed on the display unit and a first inorganic layer disposed on the first organic layer.

12. The display device of claim 11 , wherein the mirror member is disposed on the first organic layer or the first inorganic layer.

13. A display device comprising:
a display driver configured to provide a driving signal to a plurality of pixels;
a substrate;
an encapsulation unit opposite to the substrate;
a display unit disposed between the substrate and the encapsulation unit, the display unit including the plurality of pixels;
a camera unit disposed on one side of the substrate, the camera unit including at least one camera module and controlled based on a camera control signal; and
a mirror member disposed on one side of the encapsulation unit,
wherein each of the plurality of pixels includes:
a sub-pixel having an organic light emitting diode that is located in an emission region of a plurality of emission regions; and
a transparent window located in a transparent region of a plurality of transparent regions,
wherein the mirror member is physically apart from the organic light emitting diode, the mirror member includes:
a plurality of mirror patterns disposed on the one side of the encapsulation unit, the mirror patterns located in a mirror region and including a plurality of openings overlapping the plurality of emission regions and the plurality of transparent regions in a plan view; and
a mirror layer disposed on the mirror patterns and the one side of the encapsulation unit, the mirror layer located in the emission region, the mirror region, and the transparent region, and
wherein a reflectivity of the mirror patterns is higher than a reflectivity of the mirror layer.

14. The display device of claim 13 , wherein the display driver includes:
a scan driver configured to provide a scan signal to the plurality of pixels;
a data driver configured to provide a data signal to the plurality of pixels;
an emission driver configured to provide an emission control signal to the plurality of pixels;
a camera driver configured to generate the camera control signal; and
a controller configured to control the scan driver, the data driver, the emission driver, and the camera driver.

15. The display device of claim 14 , wherein the controller generates a control signal for operating the plurality of pixels by a simultaneous emission driving manner in which a single frame is divided into a non-emission period in which the plurality of pixels are in a non-emission state while the data signal is supplied to the plurality of pixels, and an emission period in which the plurality of pixels are in an emission state.

16. The display device of claim 15 , wherein the camera driver generates the camera control signal such that the camera unit is turned-off in the emission period.

17. The display device of claim 15 , wherein the camera driver generates the camera control signal such that the camera unit is turned-on during the non-emission period.
