1. A backlight unit having light emitting diodes comprising:

  • a substrate disposed thereon with conductive lines;

    a plurality of light emitting diodes each bonded to an upper surface of the substrate and spaced a predetermined distance apart from the substrate, and electrically connected to the conductive lines of the substrate;

    a transparent resin encompassing the plurality of light emitting diodes and formed on the upper surface of the substrate; and

    optical transmission means disposed on an upper surface of the transparent resin, the means including first means for preventing light emitted from the light emitting diodes from being totally reflected by allowing an incident angle of the light to be less than a threshold angle, and second means for diffusing and emitting the light.
