A lamp unit for a vehicular lamp system performing selective light irradiation to the surroundings of the own vehicle includes: a light source; an optical shutter part that modulates light emitted from the light source; and an optical system that projects the light transmitted through the optical shutter part. The optical shutter part includes: polarizers; a liquid crystal element disposed between the polarizers and where the initial alignment of liquid crystal molecules is horizontally aligned and causes an alignment change in the in-plane direction upon electric field application; a first optical plate which is a positive A-plate disposed between the polarizers closer to the light source and the liquid crystal element; and a second optical plate which is a positive C-plate disposed between the first optical plate and the liquid crystal element.
