Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a backlight unit and to provide a liquid crystal display device employing the same. SOLUTION: This backlight unit includes: a plurality of light emitting device units arranged on a base plate to form at least one line, an optical plate positioned above the plurality of light emitting units, and a light transmission diffusion plate positioned on the optical plate to diffuse and transmit incident light. The optical plate comprises: a plurality of reflection mirrors formed on the bottom surface thereof to face the plurality of light emitting device units to reflect light directly emitted upward from the plurality of light emitting device units, and a saw-tooth reflection/refraction pattern formed on the opposite surface thereof to further spread incident light by reflection.
