A backlight unit of a liquid crystal display includes a plurality of light
emitting diode packages arranged in a matrix while being spaced a uniform
distance apart from each other. Each light emitting diode package
includes one or more light emitting diode chips and is structured such
that light generated from the light emitting chips is emitted in the
horizontal direction. A reflector consists of a plurality of reflection
cells connected to each other in a matrix. Each of the reflection cells
of a unit size has each of the light generating packages positioned at
the center thereof, and reflects the light, emitted from the light
emitting diode at the center thereof in the horizontal direction, in the
vertical direction.
