Abstract

An image display device including a laser light source; an optical element; and a transmitting-reflecting member, the image display device which displays an image by forming the image by light which is emitted from the laser light source and making image light after forming the image to be incident on the transmitting-reflecting member, wherein the laser light source is arranged such that there are more S polarization components of the image light which is incident on the transmitting-reflecting member with respect to the transmitting-reflecting member than P polarization components, and a mobile object including the image display device.
