| abstract | An image display apparatus capable of providing a sufficiently good image with respect to a shift of a crystalline lens from the center of an eyepiece generated when an eyeball is moved and a chromatic aberration at that time is also provided. Light emitted from a two-dimensional light emitting type first photoelectric element orthogonal to a light beam emission direction is projected onto first and second light diffusers independent of the left and right eyes via a relay optical system. And image display for projecting and forming a wide-area image with a viewing angle of ± 22.5 ° or more on the retina in the eyeball through the first and second eyepiece optical systems corresponding to the light diffuser, respectively. A distance between centers of the first and second light diffuser images is in the range of 5.5 to 7.5 cm, and the first and second eyepiece optical systems are each composed of a plurality of eyeball lenses. And at least one of the lens surfaces of the convex lens is a conic surface having a conic constant K <−1, and the light diffuser is a micron grade of metal oxide or metal carbide and has a fine particle size. Transmission type diffuser with coated abrasive grains coated on the transmission plate An image display apparatus is provided. [Selection] Figure 4A |
