PURPOSE: A junction structure between PCB and flexible printed circuit cable is provided to improve junction efficiency by preventing non-soldered area and thermal loss during junction. CONSTITUTION: A junction structure comprises a PCB having a plurality of patterns formed at an end of the PCB, and dummy patterns(120) formed at both ends of the string of patterns, wherein dummy patterns are not connected to an internal circuit; and a flexible printed circuit cable(200) having a plurality of patterns(210) formed to be longer than the patterns formed at the PCB, and dummy patterns(220) formed at both ends of the string of patterns, wherein dummy pattern are not connected to the internal circuit. The junction surface between the PCB and the flexible printed circuit cable has at least one reference hole(230).
