Abstract
The present invention makes it possible to reduce a difference in resolution between respective regions of a virtual image while reducing distortion of an image. A translucent screen is disposed to be inclined with respect to an optical axis of projection light such that a difference between a first optical path length to a first reflection part of the display light emitted from a first end far from display light reflected toward a second reflection part by the first reflection part, and a second optical path length of display light emitted from a second end closer to reflected toward the second reflection part by the first reflection part than the first end becomes smaller.
