PURPOSE: An edge lighting back light unit is provided to replace an LED light source by mixing the LED light source and an LED bar and to minimize an optical mixing space by laminating an LED bar array, a pattern diffusing plate, and parts of an optical sheet. CONSTITUTION: An LED(Light Emitting Diode) light source(112) is attached to the side of an LED bar array. The LED bar array reflects the light of the LED light source to the upward. LED bars(110-1) are arranged on the upper side of the LED bar array in a constant interval. A protrusion(116) for securing a recycling space is included on the LED bar. A diffusing plate is laminated on the upper of the LED bar array. A prism sheet concentrates the light on the diffusing plate using a prism pattern. |
