To provide an eye glass display capable of preventing the defocus of an image projected to eyes even when the image projection lens after lens grinding processing is applied on the lens is different in size.

A slope-like guide groove 11 is graved in the image projection lens 3. The guide groove 11 is formed so that it become deeper on the outer side of the image projection lens 3 and shallower on the center side of the lens 3. A guide part 12 is disposed in a display unit 9, and the leading end part of the guide part 12 comes in contact with the guide groove 11. Thus, in the case of a large-sized image projection lens 3, as shown in Fig. (a), the guide part 12 comes in contact with the deep part of the guide groove 11, then, the display unit 9 is positioned close to the image projection lens 3. On the other hand, in the case of the small-sized image projection lens 3, as shown in Fig.(b), the guide part 12 comes in contact with the shallow part of the guide groove 11, then, the display unit 9 is positioned away from the image projection lens 3. Consequently, an optical path length from the display unit 9 to an HOE 5 never change.
