There is provided an excellent image display device allowing observation of a surrounding scene by a video see-through method. While an authentication process is being performed, a head-mounted display 100 superimposes, and displays, an authentication screen on a video see-through image captured by an outside camera 312. Accordingly, a user is enabled to observe the surrounding scene by the video see-through image during the authentication process. Even when using the head-mounted display 100 while walking outdoors, the user is enabled to constantly grasp his/her surroundings, and the safety may be secured.

It is an object of the present invention to provide a configuration which are less likely to cause a distortion in an observed image when the position of the image display device in the eyeball direction of an observer is adjusted. An image display device according to the present invention includes: an image formation device (40); and an optical system (52) that brings an image from the image formation device (40) to an eyeball (11) of an observer. 0 (degrees).sub.2<.sub.1 is satisfied where an image-formation-device first strike point (CP.sub.1) is defined as a point where an extended line of an optical axis of the optical system (52) intersects with an image exit surface of the image formation device (40), a first normal line (NL.sub.1) is defined as a normal line to the image exit surface of the image formation device (40) passing through the first strike point (CP.sub.1), an image-formation-device second strike point (CP.sub.2) is defined as a point where an extended line of a pupil center line of the eyeball (11) of the observer intersects with the image exit surface of the image formation device (40), a second normal line (NL.sub.2) is defined as a normal line to the image exit surface of the image formation device (40) passing through the second strike point (CP.sub.2), and .sub.1 represents an angle between the extended line of the optical axis of the optical system (52) and the first normal line (NL.sub.1), and .sub.2 represents an angle between the extended line of the pupil center line of the eyeball of the observer and the second normal line (NL.sub.2).
