PURPOSE: A liquid crystal display device is provided to prevent hot-spot and light leakage of a light incoming unit by changing a shape of a prism sheet into a saw tooth shape. CONSTITUTION: One part of a lower prism sheet(142) is cut off by an area where light leakage is not generated in an area where an LED(Light Emitting Diode) array is faced. One part of the lower prism sheet forms a saw tooth shape. A light is not incident to a lower prism sheet through a light guide plate(120). The light is incident to an upper prism sheet(141). It prevents light leakage by the upper prism sheet. |
