Title:
IMAGE DISPLAY DEVICE AND MOVING BODY
Document Type and Number:
Japanese Patent JP2020074025
Kind Code:
A
Abstract:
To provide an image display device that can improve visibility of a virtual image.SOLUTION: An image display device 1000 forms an image with light from a semiconductor laser, and makes image light after forming the image incident on a transmission reflection member (reflection surface element 10). In the image display device, the semiconductor laser is arranged so that an S-polarization component of the image light made incident on the transmission reflection member becomes larger than a P-polarization component of the image light with respect to the transmission reflection member. In this case, visibility of a virtual image can be improved.SELECTED DRAWING: Figure 1
