Line filter and display device comprising same

A display device including a display panel, the display device comprising:

• a power supply board, configured to supply power to the display device, and including a line filter,
• wherein the line filter is configured to remove noise and the line filter includes:
• a case, connectable to a printed circuit board to thereby allow the line filter to be electrically connected to the printed circuit board;
• a magnetic core to be accommodated in the case while the case is connected to the printed circuit board;
• a core cover coupleable to the case to cover the magnetic core while the magnetic core is accommodated in the case;
• a coil wound around an outside of the case and the core cover;
• and
• a separator coupleable to the case and the core cover,
• wherein the separator includes:
• a base;
• an isolating portion protruding from the base to be insertable into the case and the core cover to thereby allow the separator to be coupled to the case and the core cover so as to isolate a region in which the coil is wound;
• and
• a stepped portion protruding from the base and in contact with one surface of the case to separate the base from the printed circuit board,
• wherein at least a portion of the case is disposed on one side of the printed circuit board, and
• wherein the base is disposed spaced apart from the printed circuit board on another side opposite to the one side of the printed circuit board.
