Abstract
A virtual image display device includes a display surface and a projection optical system that projects a light ray from the display surface toward a transparent member. The projection optical system includes a convex lens. An optical path of a first light ray, which is emitted from one point on the display surface and is reflected by the front surface of the transparent member coincides with an optical path of a second light ray, which is emitted from the one point and is reflected by the back surface of the transparent member, due to refraction in the convex lens. The center of the convex lens is displaced from a reference axis Z that passes through the one point and extends in a direction perpendicular to the display surface. The display surface is positioned closer to the convex lens than a focal point of the projection optical system.
