Abstract
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.
