Abstract

Provided are a heat radiation printed circuit board and a method of manufacturing the same, the heat radiation printed circuit board being produced by the method including: forming a circuit layer having an insulating layer, a circuit pattern and a solder resist on a first area of one surface of a metal substrate; and forming a bending part in a second area, in which the insulating layer is not formed, by bending the metal substrate, whereby a crack can be prevented in advance from being generated in the insulating layer, and durability and reliability of the heat radiation printed circuit board and a backlight unit applying the same can be improved.
