Patent ID: 8523417

Claim:
A vehicular headlamp comprising: a projection lens disposed on an optical axis extending in a vehicular longitudinal, direction, a light source disposed rearwardly of a rear-side focal point of the projection lens, a reflector disposed rearwardly of the rear-side focal point of the projection lens to reflect light from the light source toward the projection lens, and a liquid crystal shutter disposed in the proximity of the rear-side focal point of the projection lens, wherein the liquid crystal shutter comprises: a pair of transparent plates disposed at a predetermined interval in a direction of the optical axis, a liquid crystal member disposed between the pair of transparent plates, and a pair of polarization plates disposed on an outer surface of the pair of transparent plates, wherein the liquid crystal member is disposed only in a part of an area between the pair of transparent plates, wherein the pair of polarization plates are disposed only in an area of the outer surface of the pair of transparent plates corresponding to an area in which the liquid crystal member is disposed, and wherein the area in which the liquid crystal member is disposed comprises: a first area for blocking a part of reflected light from the reflector such that light emitted from the projection lens forms a low-beam distribution pattern having a cut-off line at an upper end edge, and a second area for blocking light emitted from the projection lens and then reflected by a road surface ahead of a vehicle toward a space above the cut-off line.
