Abstract
A virtual image display device includes a display element, a light-guiding system configured to guide imaging light that exits the display element, and a mirror member having a first surface where the imaging light that exits the light-guiding system is incident while being refracted and a second surface that reflects the imaging light that passes through the first surface and causes the imaging light to exit the mirror member through the first surface where the imaging light is refracted. In the mirror member, the curvature of the first surface differs from the curvature of the second surface.
