Abstract

A bonding method of a flexible film is provided, which includes: positioning an anisotropic conductive film on a plurality of first signal lines formed on the flexible film to be bonded to a thin film transistor (TFT) panel; arranging the anisotropic conductive film on the TFT panel to align the first signal lines formed on the flexible film and a plurality of second signal lines formed on the TFT panel; positioning at least one portion of a protection film for protecting the second signal lines of the flexible film to be overlapped with the TFT panel; and pressing the flexible film and the TFT panel.

Claims (11)

1. A display device comprising:

a thin film transistor (TFT) panel including a plurality of first signal lines;

a flexible film including a plurality of second signal lines and a protection film protecting the second signal lines; and

an anisotropic conductive film connecting the first signal lines and the second signal lines, wherein the protection film exposes a portion of the second signal lines, the first signal lines and the exposed second signal lines are aligned to match each other, and a portion of the protection film overlaps the TFT panel, and a portion of the protection film adjacent the anisotropic conductive film has an end with an uneven shape of a constant thickness.

2. The device of claim 1 , wherein the anisotropic conductive film overlaps at least one portion of a flexible body of the flexible film.

3. The device of claim 1 , further comprising forming a cover layer on a surface of the flexible film which is not attached to the anisotropic conductive film.

4. The device of claim 3 , wherein the cover layer is formed on a portion of the TFT panel.

5. The method of claim 1 , wherein dummy lines without signal transmission capabilities are formed beside the second signal lines.

6. The device of claim 5 , wherein the dummy lines are the outermost lines with respect to the second signal lines.

7. The device of claim 5 , wherein the dummy lines have widths wider than widths of the second signal lines.

8. The device of claim 5 , wherein the number of dummy lines is two or more.
