Patent ID: 7633761

Claim:
A flexible circuit film comprising: a base substrate having a first surface and a second surface opposite the first surface; a driver chip formed on the base substrate; a first signal transmission line formed on the first surface of the base substrate, the first signal transmission line being electrically connected to an output terminal of the driver chip; a second signal transmission line formed on the first surface of the base substrate, the second signal transmission line being electrically connected to an input terminal of the driver chip; a first crack-preventing portion formed on the second surface of the base substrate and disposed corresponding to an angled portion of the first signal transmission line to prevent the angled portion of the first signal transmission line from cracking; and a second crack-preventing portion formed on the second surface of the base substrate and disposed corresponding to an angled portion of the second signal transmission line to prevent the angled portion of the second signal transmission line from cracking.
