A vehicular headlamp (10) includes a projection lens (12), a light source (14a), a reflector (16), and a liquid crystal shutter (20). The liquid crystal shutter (20) includes a pair of transparent plates (32), a liquid crystal member (34), and a pair of polarization plates (36). The liquid crystal member (34) is disposed only in a part of an area between the pair of transparent plates (32). The pair of polarization plates (36) are disposed only in an area of the outer surface of the pair of transparent plates (32) corresponding to an area in which the liquid crystal member (34) is disposed. The area in which the liquid crystal member (34) is disposed includes a first area (Z1) for blocking a part of reflected light from the reflector such that light emitted from the projection lens (12) forms a low-beam distribution pattern having a cut-off line at an upper end edge, and a second area (Z2) for blocking light emitted from the projection lens (12) and then reflected by a road surface ahead of a vehicle toward a space above the cut-off line. |
