    Abstract: A backlight unit and an LCD(Liquid Crystal Display) having the same are provided to suppress the loss of light in an air layer positioned between a light guiding plate and a reflecting layer, by coating a rear surface of the light guiding plate with a reflective material having higher refractive index than the light guiding plate so as to totally reflect the light advancing in a direction of the rear surface of the light guiding plate. A lamp(134) generates light. A light guiding plate(112) guides the light generated from the lamp. A coating layer(120) is formed on a rear surface of the light guiding plate to reflect the light advancing in a direction of the rear surface of the light guiding plate. The coating layer has a higher refractive index than the light guiding plate. The coating layer is formed of aluminum or silver. An anti-oxidizing layer is formed on a surface of the coating layer to prevent the oxidation of the coating layer.
