Problems solved by technology

[0005] However, since the human body is not bilaterally symmetrical, if the adjustment mechanism of the conventional head-mounted display is used to adjust the eye width, the eye width may not be appropriate due to different observers.

Abstract

Provided is an image display device. Interpupillary adjustment can be carried out properly and rapidly according to different observers. The image display device is characterized in that the image display device used while mounted on a head of an observer includes: a left-eye display unit having an optical section adapted to form a virtual image for a left eye of the observer; a right-eye display unit having an optical section adapted to form a virtual image for a right eye of the observer; and an interpupillary adjustment mechanism adapted to adjust a distance between the left-eye display unit and the right-eye display unit, wherein the interpupillary adjustment mechanism includes a first adjustment mechanism capable of simultaneously adjusting a position of the left-eye display unit and a position of the right-eye display unit, and a second adjustment mechanism capable of independently adjusting only either one of the position of the left-eye display unit and the position of the right-eye display unit.

Description

Technical field [0001] The present invention relates to an image display device. Background technique [0002] Provided is an application of a head-mounted display (HMD: HeadMount Display) that is installed on the head of an observer and used and displays an image recognized by the observer as a virtual image (for example, refer to Patent Document 1). [0003] This head-mounted display has an adjustment mechanism for adjusting the distance (eye width) between the display unit for the left eye and the display unit for the right eye. This adjustment mechanism moves the display unit for the left eye and the display unit for the right eye symmetrically in conjunction with each other. [0004] Patent Document 1: Japanese Patent Application Publication No. 2007-81984 [0005] However, since the human body is not symmetrical, if the eye width is adjusted by the adjustment mechanism of the conventional head mounted display, the eye width may be inappropriate due to different observers.
