An LCD includes an LCD panel, a light guiding plate including a light guiding plate main body disposed behind the LCD panel and a reflective polarizing layer formed on a surface of the light guiding plate main body to face the LCD panel, and a light source disposed on at least one side of the light guiding plate. The LCD has a high light efficiency by using a light guiding plate since a reflective polarizing layer is formed on the light guiding plate.
