A back light unit and a manufacturing method thereof capable of improving efficiency of a manufacturing process are disclosed. The back light unit includes a light source, a light guiding plate which uniformly transmits a light beam generated by the light source, and a cover portion which forms an external appearance and fixes the light guiding plate, wherein a resin material is charged between the light guiding plate and the cover portion to couple the light guiding plate and the cover portion.

Back light unit and manufacturing method thereof

A back light unit, in which bright lines produced from point light sources, light emitting diodes, in an oblique direction are removed, so that brightness can be uniformly maintained at a liquid crystal panel. The back light unit includes a prism light guide plate, light emitting diodes provided on one side of the prism light guide plate, and a bright-line dead section provided to the prism light guide plate so as to uniformly scatter light of each light condensing section generated by light emitted from the light emitting diodes, to prevent a spectrum of the light in a specific direction, and to prevent bright lines from being produced.
