Abstract: A display device includes a pixel, a signal line electrically connected to the pixel, and a signal pad connected to the signal line. The signal pad includes a first conductive pattern disposed on the pad part, a second conductive pattern disposed on the first conductive pattern, and an insulating pattern, which, in a cross-section, is disposed between the pad part of the signal line and the second conductive pattern, and in a plan view, overlaps the second conductive pattern. The insulating pattern passes through the first conductive pattern via an upper reinforcement hole defined in the first conductive pattern.

Abstract: A display device includes a first conductive pattern layer connected to a signal line, a second conductive pattern layer connected to the first conductive pattern layer, and an insulation pattern layer disposed between the signal line and the second conductive pattern layer and overlapping the second conductive pattern layer. The second conductive pattern layer exposes a portion of an upper surface and a side surface of the insulation pattern layer. The second conductive pattern layer includes first and second edge portions disposed on the upper surface of the insulation pattern layer and facing each other in a second direction intersecting a first direction. A distance between the first and second edge portions decreases as moving along the first direction in a first region of the upper surface of the insulation pattern layer, and increases as moving along the first direction in a second region of the upper surface.
