Abstract:
An image display apparatus comprising a display section for displaying an image, an eyepiece optical system, and a transparent plate-shaped member for holding the eyepiece optical system, the image display apparatus being used with the eyepiece optical system placed in front of a viewer's eyes and with the plate-shaped member facing the eyes, the image display apparatus directing light from the display section via the eyepiece optical system to the eyes so that the viewer is presented with a virtual image of the image displayed on the display section and simultaneously permitting light from an outside world to be transmitted through the plate-shaped member so as to be directed to the eyes so that the viewer is presented with an image of the outside world,wherein a boundary surface between the eyepiece optical system and the plate-shaped member is so arranged as not to reflect light from the outside world incident thereon at an angle of incidence greater than a Brewster angle toward the eyes.
