Light source unit and backlight assembly having the same

A light source unit comprising:

• a light-emitting diode(s) housing package (LED package) which houses at least one LED chip;
• and
• a printed circuit board on which the LED package is mounted,
• wherein the printed circuit board comprises a support plate, a first conductive member disposed directly on the support plate and electrically connected to the LED chip, and a second conductive member disposed directly on the support plate, the second conductive member is spaced apart from the first conductive member and is electrically connected to the LED chip,
• wherein the first conductive member directly contacts a side of the LED package, the second conductive member directly contacts another side of the LED package which is opposite the side of the LED package, and the first conductive member comprises a first protrusion which protrudes toward the second conductive member, and the second conductive member comprises a second protrusion which protrudes toward the first protrusion,
• wherein the LED package and the first protrusion are spaced apart and connected electrically in parallel,
• wherein the first protrusion and second protrusion comprise a metal, and
• wherein the first protrusion and the second protrusion are disposed between the support plate and the LED package and are not disposed below the LED package.
