US Patent 10983423 Image display device

An image display device includes a display unit which displays a first image and a second image, and a projection optical system which directs light of the first image and light of the second image toward a windshield. The display unit displays the first image and the second image in different display areas on the same plane. The projection optical system sets an image point of the light of the first image and an image point of the light of the second image, so that a first virtual image and a second virtual image are formed at positions having different distances from a viewing point within a visible area.
