1. A display device, comprising:
a substrate including an active area and a non-active area which encloses the active area;
a transistor on the substrate in the active area;
a planarizing layer on the substrate and the transistor in the active area and the non-active area;
a light emitting diode which is on the planarizing layer in the active area and includes an anode, an organic light emitting layer, and a cathode;
a first conductive pattern on the planarizing layer in the non-active area;
a second conductive pattern on the first conductive pattern in the non-active area; and
a plurality of dummy organic patterns which is disposed between the first conductive pattern and the second conductive pattern and is formed of the same material as the organic light emitting layer,
wherein an air gap is disposed between the plurality of dummy organic patterns.
