摘要： A viewing optical system for display apparatus, includes an ocular optical member for leading an observation image formed by an observation image forming member to an exit pupil has a first prism member and a second prism member. The first prism member has a first entrance surface, a reflecting surface and a first exit surface disposed to face each other across a first prism medium. The second prism member has a second entrance surface and a second exit surface disposed to face each other across a second prism medium. The first and second prism members are cemented together with a holographic element interposed between the first exit surface and the second entrance surface. The reflecting surface has a positive power. The first exit surface and the second entrance surface are each formed from a plane or cylindrical surface. The holographic element also has a plane of cylindrical surface.

摘要： A full-color hologram capable of generating a bright image and reproducing colors in all color regions is formed by multiple recording or multilayer recording with four different dominant wavelengths for reconstruction. The full-color hologram has one reconstruction wavelength in the vicinity of the peak wavelength 555 nm of the spectral luminous efficiency curve, i.e. in the range of 550 nm to 560 nm, and further has three other reconstruction wavelengths in the three primary color regions of red, blue and green, i.e. in the three regions of 615 nm to 680 nm, 380 nm to 470 nm, and 485 nm to 515 nm, respectively.
