Abstract: A display device includes a display substrate comprising a polymer layer including a first non-bending area, a second non-bending area that overlaps the first non-bending area when viewed in a plan view, and a bending area arranged between the first non-bending area and the second non-bending area. A display element layer is disposed on the polymer layer. A plurality of signal pad groups is disposed in the second non-bending area and is configured to be electrically connected to the display element layer. An upper substrate is disposed on a top surface of the display substrate. A flexible circuit board comprising a plurality of connection pad groups is arranged in correspondence to the signal pad groups. An area of the upper substrate is larger than an area of the display substrate when viewed in a plan view.

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.
