A lighting device according en embodiment of the present invention comprises: multiple light sources to emit light; a printed circuit board having the light sources which are arranged at predetermined intervals; a reflective film layer to reflect the light emitted from the light sources to the front surface of the lighting device; multiple light emitting rods located on the reflective film layer; and a pattern printing unit which is formed to be printed on the reflective film layer and is located in correspondence to each of the light emitting rods. The lighting device of the present invention uses the light emitting rods instead of a light guide panel, and comprises the pattern printing unit formed between the light emitting rod and the reflective film layer, thereby making light brightness uniform in the surface of a backlight unit, reducing the thickness of the lighting device, and reducing manufacturing costs. |
