A chip-on film and a display device including the same are disclosed. The chip-on film includes a first base film, a second base film positioned on the first base film, a film pad portion positioned on at least one side of the second base film and exposed to the outside of the first base film, and a coating layer positioned on one surface of the first base film.

Flexible interconnects, flexible integrated circuit systems and devices, and methods of making and using flexible integrated circuitry are presented herein. A flexible integrated circuit system is disclosed which includes first and second discrete devices that are electrically connected by a discrete flexible interconnect. The first discrete devices includes a first flexible multi-layer integrated circuit (IC) package with a first electrical connection pad on an outer surface thereof. The second discrete device includes a second flexible multi-layer integrated circuit (IC) package with a second electrical connection pad on an outer surface thereof. The discrete flexible interconnect is attached to and electrically connects the first electrical connection pad of the first discrete device to the second electrical connection pad of the second discrete device.
