The disclosure is related to a flexible printed circuit board. The flexible printed circuit board comprises a connecting area and a plurality of gold fingers disposed inside the connecting area, wherein the distances of the gold fingers are different. The disclosure is further related to a liquid crystal display. By the above manner, the disclosure is able to change the distances between the adjacent gold fingers to increase the number of the gold fingers without changing the size of the flexible printed circuit board so as to solve the impedance matching problem of the gold fingers of the flexible printed circuit board, and in the meanwhile to increase the assembling yield rate of the flexible printed circuit board.
