Abstract:
In a vehicular lamp, a polarization rotation element is disposed only in an optical path of second light from a second reflector toward a PBS, first light and the second light condensed toward a liquid crystal element are condensed at a first condensing point in common, the liquid crystal element is located at the first condensing point, the second light reflected by the PBS is condensed at a second condensing point deviated from the optical path of the light from a first reflector toward the PBS and the optical path of the second light from the second reflector toward the PBS.
