ABSTRACT:
An exemplary flexible printed circuit board (2) includes a wiring layer (21). The wiring layer includes a number of conductive lines (211). Each of the conductive lines includes a finger (213), a line portion (212) and a junction portion (214) between the finger and the line portion. A width of the finger is greater than a width of the line portion, a width of the junction portion gradually changes from the width of the line portion to the width of the finger. The flexible printed circuit board has high reliability.
