1. A transparent display device, comprising:
a substrate provided thereon with a display area, in which a plurality of subpixels is disposed, and a non-display area adjacent to the display area;
anode electrodes provided in each of the plurality of subpixels over the substrate;
a light emitting layer provided over the anode electrodes;
a cathode electrode provided over the light emitting layer;
a pixel power line provided over the substrate and extended in the display area in a first direction;
a common power line provided over the substrate and extended in the display area in the first direction; and
a gate line extended in a second direction crossing the common power line and the pixel power line,
wherein the display area includes a non-transmissive area provided with the common power line and the pixel power line, and a transmissive area that transmits external light and is provided between the common power line and the pixel power line,
wherein the anode electrodes include a first anode electrode on the common power line, a third anode electrode on the pixel power line, and a second anode electrode provided between the first anode electrode and the third anode electrode, and
wherein at least a part of the first anode electrode is disposed to overlap a first overlapping area where the common power line and the gate line overlap each other, and at least a part of the third anode electrode is disposed to overlap a second overlapping area where the pixel power line and the gate line overlap each other.
