Abstract

In a projector according to an aspect of the present disclosure, first light in a first wavelength band output from a first light source sequentially passes through a first light guiding part and a first parallelizing part and enters a light combiner. Second light in a second wavelength band output from a second light source sequentially passes through a second light guiding part and a second parallelizing part and enters the light combiner. Third light in a third wavelength band output from a third light source sequentially passes through a third light guiding part and a third parallelizing part and enters the light combiner. A first focal length of the first parallelizing part is longer than a first length from a first light incident end to a first light exiting end of the first light guiding part, a second focal length of the second parallelizing part is longer than a second length from a second light incident end to a second light exiting end of the second light guiding part, and a third focal length of the third parallelizing part is longer than a third length from a third light incident end to a third light exiting end of the third light guiding part.
