Abstract
A pattern structure for a display device includes a substrate, a protrusion pattern on the substrate, a first conductive pattern covering an upper surface of the protrusion pattern, an interlayer insulating layer on the first conductive pattern and including a contact hole, and a second conductive pattern on the interlayer insulating layer and connected to the first conductive pattern. The contact hole overlaps the protrusion pattern and the first conductive pattern.
