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.
Claims13
An image display device, comprising:
- a laser light source;
- an optical element;
- and
- a transmitting-reflecting member,
- wherein the image display device displays an image by forming the image by light that is emitted from the laser light source and makes image light after forming the image 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 that is incident on the transmitting-reflecting member with respect to the transmitting-reflecting member than P polarization components,
- wherein the optical element is arranged on an optical path between the laser light source and the transmitting-reflecting member, and is a lens array which includes a plurality of lenses on which the image is formed,
- an effective cross-section of the light that is emitted from the laser light source is one of vertically long and horizontally long with respect to the transmitting-reflecting member, and
- an effective cross-section of light that has been transmitted through the lens array is the other of horizontally long and vertically long with respect to the transmitting-reflecting member.
