Abstract: A display device is disclosed. An example display device according to an embodiment of the present disclosure includes a substrate configured to define a plurality of pixel areas disposed to be spaced apart from each other. The device includes a plurality of transmissive areas disposed between the plurality of pixel areas. The device includes a plurality of pixels disposed in the plurality of pixel areas and each including a plurality of sub pixels. The device includes a plurality of repair lines disposed between the plurality of sub pixels and made of a transparent conductive material, in which the plurality of repair lines is disposed on the same layer and spaced apart from each other. Therefore, the repair lines, which are used to repair the plurality of sub pixels when the plurality of sub pixels is defective, may be formed as a single-layer structure made of a transparent conductive material.
