Patent attributes
An image display device includes an image formation device and an optical system that brings an image from the image formation device to an eyeball of an observer. 0 (degrees)≤ω2<ω1 is satisfied where an image-formation-device first strike point (CP1) is a point where an extended line of an optical axis of the optical system intersects with an image exit surface of the image formation device, an image-formation-device second strike point (CP2) is a point where an extended line of a pupil center line of the eyeball of the observer intersects with the image exit surface of the image formation device, ω1 represents an angle between the extended line of the optical axis of the optical system and a first normal line (NL1), and ω2 represents an angle between the extended line of the pupil center line and a second normal line (NL2).
