摘要： A backlight unit and an LCD apparatus employing the same. The backlight unit includes: a base plate, a plurality of light emitting units arranged on the base plate to form at least one line, an optical plate disposed above the plurality of light emitting units, and a light transmission diffusion plate disposed on the optical plate to diffuse and transmit incident light. The optical plate includes: a plurality of reflection mirrors formed at a lower surface thereof to face the plurality of light emitting units to reflect light directly emitted upward from the plurality of light emitting device units, and a saw-tooth reflection/refraction pattern formed at an upper surface thereof to spread incident light at a wide angle.
