Abstract

A beam splitter outputs a light, which includes two polarized light components, when the splitter receives laser lights from laser light sources. The splitter is arranged such that when the light, which is outputted from the splitter and is reflected by or transmitted through a screen, is incident on a projection surface of a windshield, polarization directions of the two polarized light components are different from each other and are not parallel to a plane of incidence, which is formed at a point of incidence of the light on the projection surface.
