Abstract: A display device includes a substrate including a display area and a peripheral area surrounding the display area, a plurality of pads in a first direction of the peripheral area of the substrate and in a second direction perpendicular to the first direction, and a circuit film on the pads. Each of the pads includes a signal line on the substrate, a first dummy pattern on the substrate and spaced apart from the signal line in the first direction, and a first insulating pattern between the signal line and the first dummy pattern on the substrate.

Abstract: A display device includes a display panel including a pixel layer displaying an image, and a pad part electrically connected to the pixel layer. The display device includes a flexible circuit film combined with the pad part of the display panel. The flexible circuit film includes a base film, a first conductive line disposed on a first surface of the base film, a first conductive pad extending from the first conductive line and electrically connected to the pad part of the display panel, a cover layer covering the first conductive line and exposing the first conductive pad, and a protrusion pattern disposed on the cover layer, adjacent to the first conductive pad, and facing a side surface of the display panel.
