1. A display device comprising:
a substrate including a first area and a bending area adjacent to the first area:
a conductive line disposed on the substrate, the conductive line including a first part disposed in the first area and a second part disposed in the bending area:
a first inorganic insulating laver disposed between the substrate and the first part; and
an organic insulating laver disposed between the substrate and the first and second parts, wherein the second part is flat,
the first part includes a sloped portion with respect to an upper surface of the substrate, the sloped portion overlapping at least an edge of the first Inorganic insulating laver, and
the conductive line includes at least one protrusion protruding alternately at right and left sides along a length of the conductive line in a direction perpendicular to an extending direction of the conductive ling in a plan view, and
wherein a width of the conductive line measured in the direction perpendicular to the extending direction of the conductive line is greater in a portion including the at least one protrusion than in a portion not including the at least one protrusion.
