Abstract
A vehicular lamp includes: a light source; a projection optical system that projects light emitted from the light source forward; a liquid crystal element arranged at a rear focal point of the projection optical system; a first polarizing plate disposed in an optical path between the liquid crystal element and the projection optical system, for transmitting light of a specific polarization component; a condensing optical system that condenses the light toward the liquid crystal element; a polarizing beam splitter that transmits first light with one polarization component and reflects and separates second light with the other polarization component; a reflecting optical system that reflects the first light toward the liquid crystal element; and a polarization rotation element that rotates a polarization direction of one of the first light and the second light to coincide with the other light in terms of a polarization direction thereof.
