Claims
- 1. An image display device comprising:illuminating means; projecting means; reflection type light valve means having a light incidence/reflection plane; and an almost hermetically closed space shut off from the outside air, wherein said illuminating means illuminates said reflection type light valve means and said projecting means projects light reflected by said reflection type light valve means to make a screen image, and wherein said almost hermetically closed space comprises a plurality of structural members and the light incidence/reflection plane of said reflection type light valve means contacts at least two structural members of said plurality of structural members.
- 2. An image display device comprising:illuminating means; projecting means; reflection type light valve means having a light incidence/reflection plane; an almost hermetically closed space shut off from the outside air; and position adjusting means for adjusting a position of said reflection type light valve means, wherein said position adjusting means are provided outside said almost hermetically closed space, and wherein said illuminating means illuminates said reflection type light valve means and said projecting means projects light reflected by said reflection type light valve means to make a screen image.
- 3. An image display device comprising:illuminating means; projecting means; reflection type light valve means having a light incidence/reflection plane; an almost hermetically closed space shut off from the outside air; and position adjusting means provided in a single direction nearly orthogonal to the optical axis of illumination and the optical axis of projection and for adjusting said reflection type light valve means, wherein said illuminating means illuminates said reflection type light valve means and said projecting means projects light reflected by said reflection type light valve means to make a screen image, and wherein said almost hermetically closed space comprises a plurality of structural members and the light incidence/reflection plane of said reflection type light valve means contacts at least two structural members of said plurality of structural members.
- 4. An image display device according to claim 2, wherein a shading elastic member is interposed between said reflection type light valve means and said almost hermetically closed space.
- 5. An image display device according to claim 3, wherein a shading elastic member is interposed between said reflection type light valve means and said almost hermetically closed space.
- 6. An image display device according to claim 2, wherein said position adjusting means comprises means for adjusting the position of said reflection type light valve means in a direction of the optical axis of illumination.
- 7. An image display device according to claim 3, wherein said position adjusting means comprises means for adjusting the position of said reflection type light valve means in a direction of the optical axis of illumination.
