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.

Virtual image display device

Provided is a head-up display which facilitates the differentiation of information contained in a stereoscopic display and which enables display having a stereoscopic effect, by rotating either a first display surface of a first image generation unit corresponding to a first virtual image display surface, or a reflection unit for aiming first display light emitted from the first image generation unit at a front window shield (transmission/reflection unit), to change the angle formed by the first virtual image display surface and a second virtual image display surface.
