The present invention relates to a backlight unit capable of reducing the power consumption thereof and lengthening the lifespan of a light source, and to a liquid crystal display comprising the same. To this end, the present invention provides a backlight unit for use in a liquid crystal display including an absorbing polarizing film which allows light of a first polarization to exit and absorbs light of a second polarization, wherein the backlight unit includes a plurality of R, G and B LED light sources for generating R, G and B random polarized light, respectively, and a reflective polarizing film which allows light of a first polarization of at least one random polarized light from among R, G and B random polarized light generated from the LED light sources to exit, reflects light of a second polarization of at least one random polarized light from among R, G and B random polarized light generated from the LED light sources, and allows light of first polarization and second polarization ...
