  • FLEXIBLE FILM, DISPLAY DEVICE HAVING THE SAME AND METHOD OF FABRICATING THE DISPLAY DEVICE
    Publication number: 20100259514
    Abstract: A flexible film, a display device and a method of fabricating a display device are disclosed. The flexible film includes a polyimide film and first and second metal films formed on the polyimide film. The display device includes a panel, a driver for driving the panel, a flexible film having a circuit pattern and disposed between the panel and the driver, and a conductive film electrically connecting the panel and the driver with the flexible film. Because the metal films are formed on the polyimide film with cleaved imide rings, plating properties, adhesion strength (bond strength) and heat resistance can be improved, and a fine circuit pattern can be easily implemented.
