Light source unit, backlight unit and liquid crystal display including the same, and method thereof

A backlight unit comprising:

• a light source unit including light emitting diodes and a printed circuit board in which a fitting hole is disposed, the light emitting diodes including a lead terminal, the lead terminal including a base part and a fitting part protruding from the base part, and the fitting part of the lead terminal fitted into the fitting hole of the printed circuit board and securing the light emitting diode to the printed circuit board, the fitting part including:
• a protruding portion protruding from the base part in a first direction and is inserted into the fitting hole;
• and
• a head portion disposed at a distal end of the protruding portion and connecting the lead terminal of the light emitting diode to the printed circuit board;
• and
• a receiving member in which the light source unit is received.

A liquid crystal display comprising:

• a light source unit including light emitting diodes and a printed circuit board in which a fitting hole is disposed, the light emitting diodes including a lead terminal, the lead terminal including a base part and a fitting part protruding from the base part, and the fitting part of the lead terminal fitted into the fitting hole of the printed circuit board and securing the light emitting diode to the printed circuit board, the fitting part including:
• a protruding portion protruding from the base part in a first direction and is inserted into the fitting hole;
• and
• a head portion disposed at a distal end of the protruding portion and connecting the lead terminal of the light emitting diode to the printed circuit board;
• a receiving member in which the light source unit is received;
• and
• a liquid crystal panel disposed above the light source unit and displaying images.
