A liquid crystal display having a display panel including first and second display regions that are different from each other, a light source supplying light to the display panel, and a light guide plate having an area which is divided into a first region corresponding to the first display region and a second region corresponding to the second display region, the light guide plate allowing light incident from the light source to progress toward, wherein each of the first and second regions includes a light incident surface through which the light is incident, a light emitting surface through which the light successively incident from the light incident surface emits, and a rear surface opposed to the light emitting surface. The light emitting surface of the first region includes a plurality of first optical patterns refracting the light emitted by the light source to prevent light leakage from the first region onto the second display region.
