Abstract: PURPOSE: A white light LED(Light emitting diode) backlight unit using a quantum dot light conversion layer is provided to solve for degradation in light emitting efficiency by reducing half amplitude. CONSTITUTION: A light guide plate and a diffusion sheet(200) changes a dot emitting light emitted by a light source(100) into a surface emitting light. A quantum dot light conversion layer(300) includes a quantum dot which reproduces colors by using the surface emitting light and is separated from the light source. A polarizing plate and an LCD(Liquid Crystal Display)(400) are located on an emission path which passes through the light conversion layer.
