A guide lamp apparatus for a vehicle may include a light source, a light division lens that may be arranged on a front of the light source and divides a light emitted from the light source into a plurality of lights, and a front light collection lens that may be arranged on a front of the light division lens and forms predetermined patterned images on a road surface. The apparatus comprises a laser disposed in or adjacent to a housing. This manufacturing method can reduce the problems caused by the unwanted semiconductor layer, hence improving the quality of the TFT. Each wall plate forms open-ended slots that are symmetrically arranged.
