`IMAGE DISPLAY DEVICE AND ADJUSTMENT
`FOR ALIGNMENT
`
`BACKGROUND OF THE INVENTION
`
`[0001] 1. Field of the Invention
`[0002] The present invention relates to an image display
`device by which an optical image signal based on image
`information is projected onto a display means to display an
`image, and a method for adjusting optical elements of in the
`image display device into alignment.
`[0003] 2. Description of the Prior Art
`[0004] FIG. 95 is a diagrammatic representation of a
`conventional image display device. Reference numeral 1
`denotes a luminous elem
