Abstract
A flexible circuit board includes a base substrate, a driving chip, an input transmission line, an output transmission line and a connecting transmission line. The driving chip is on a surface of the base substrate. The input transmission line is on the surface of the base substrate and electrically connected to an input terminal of the driving chip. The output transmission line is on the surface of the base substrate and electrically connected to an output terminal of the driving chip. The input transmission line is electrically connected to the output transmission line through the connecting transmission line.
