Abstract: A display device includes a display panel including a display region in which a light emitting element and a signal line are disposed, and a non-display region which is adjacent to the display region and in which a pad connected to the signal line is disposed. The pad includes a first conductive pattern at which the pad is connected to the signal line, an insulating pattern which is on the first conductive pattern and defines protrusions adjacent to each other in a direction along the first conductive pattern, a second conductive pattern on the insulating pattern and electrically connected to the first conductive pattern, and a conductive member between the protrusions and at least partially in the second 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.
