ABSTRACT:
A flexible circuit film whose signal lines are resistant to cracking even upon bending is presented. The flexible circuit film includes a base substrate, a signal transmission line and a crack-preventing portion. The signal transmission line is formed on a first surface of the base substrate. The crack-preventing portion is formed on a portion of a second surface of the base substrate that is opposite to the first surface to prevent cracking of the signal transmission line. The crack-preventing portion is formed on the part of the flexible circuit film that is bent by a large angle when the flexible circuit film is assembled with another component.
