Abstract
The display system displays a virtual image as if it is at a target position in a target space. The system satisfies a condition where |1/L−1/Lmax| is larger than 0 but is equal to or smaller than 0.06. L[m] denotes a display distance defined as a distance from a point-of-view position for the virtual image to a display position of the virtual image. Lmax [m] denotes a maximum value of a target distance defined as a distance from the point-of-view position to the target position.
