Abstract

Disclosed herein is a backlight unit (1), capable of easily forming a curved or three-dimensional shape. The backlight unit (1) according to the present invention comprises a light guide panel (10) which includes a light guide plate having on one surface of both surfaces thereof a plurality of notches (11), an uneven dot pattern, a printed dot patter or a sanded surface, of a light diffusion plate; a luminous means which includes a lamp (31) mounted on a PCB (33) to emit light to the light guide panel (10); a groove (13) formed along an edge of the light guide panel (10) so that the luminous means is installed in the light guide panel; and a thin heat radiating plate (50) fixed on a back surface of the PCB (33) along the groove.
