A liquid crystal display, wherein a printed circuit board equipped with light emission diodes serving as a light source is disposed on the rear surface of a reflection plate, to reduce manufacturing costs of the product by reducing a number of parts forming a back light unit and to easily emit heat, includes a liquid crystal panel, light emission diodes to emit light to be illuminated on the liquid crystal panel, a printed circuit board equipped with the light emission diodes, and a reflection plate to reflect light emitted from the light emission diodes toward the liquid crystal panel and includes through holes to pass the light emission diodes therethrough, wherein the printed circuit board is coupled to a rear surface of the reflection plate.
