Abstract
A virtual image display device includes: an image forming element which forms an image to be displayed; and an optical element which reflects a light emitted from the image forming element to display a virtual image. The optical element has a concave shape opposite to a traveling direction of the light emitted from the image forming element. The light emitted from the image forming element enters the optical element without being reflected by other optical element. The image forming element is arranged in a direction substantially orthogonal to a direction of viewing the virtual image through the optical element.
