Abstract: There are provided an electromagnetic interference filter for removing common mode electromagnetic interference, in which electromagnetic interference of a low frequency band and a high frequency band is removed in a single filter because of a wide block frequency band, a power supply apparatus including the electromagnetic interference filter, and a display apparatus including the electromagnetic interference filter. The electromagnetic interference filter includes a core part including at least two legs electromagnetically coupled and forming a closed magnetic circuit; a coil part including first and second rectangular copper wires respectively wound in a single layer around the at least two legs and removing common mode electromagnetic interference included in power transferred from a power line; and a support part having a mounting area in which the core part having the coil part wound therearound is mounted.
