Abstract

Disclosed is a radiant heat circuit board mounted in a chassis providing a light guide passage of a backlight unit. The radiant heat circuit board includes a first region on which a heat generating element is mounted and a second region bent with respect to the first region, in which a bottom surface of the second region is bonded to the radiant heat adhesion layer to make contact with the bottom surface of the chassis. The radiant heat circuit board is bent to have an angle equal to or greater than 90 so that a mask is easily formed during a solder paste coating procedure, and a length of the radiant heat circuit board is extended so that thermal radiation is improved.
