1. A flexible printed circuit board (FPCB) comprising:
a circuit terminal including a circuit pattern, the circuit pattern including a plurality of pins, and the circuit terminal being configured to couple to a connector; and
a reference mark, wherein the reference mark formed in the FPCB acts as a reference point when an outer shape of the FPCB is processed, wherein the reference mark is formed to contact the circuit pattern, the reference mark being disposed at an outer edge of the circuit pattern in a width direction of the circuit terminal, wherein the reference mark includes a first reference mark and a second reference mark, wherein, in a plan view, the first reference mark partially overlaps a lengthwise direction of pins of the plurality of pins, and
wherein, in the plan view, the second reference mark does not overlap the lengthwise direction of the pins.
