<p>PURPOSE: A polarized light source, a BLU equipping the same and an LCD module for offering a polarized light BLU are provided to reduce the light loss by a DBEF(Double Brightness Enhancement Film) by equipping polarized light source. CONSTITUTION: A BLU(Backlight Unit) is arranged on a lower substrate and irradiates the light polarized to the lower plate. The BLU includes a LGP(Light Guide Plate)(63) which beneath locates an LCD panel(50) and an LED(Light Emitting Diode)(61). Non-polar LED is arranged in the side of LGP and emits the light polarized to LGP. A lower polarized film locates between the lower plate and BLU. An upper polarized film(57) emits the polarization value.</p> |
