Abstract
An information display device comprises a housing installed in an instrument panel of a motor vehicle. The housing has a window opening facing toward the vehicle cabin. A first display device is installed in the housing and has a screen on which a first image is displayed. A second display device is installed in the housing and has a screen on which a second image is displayed. A half mirror is installed and inclined in the housing in a manner to cover the screens of both the first and second display devices, so that the image forming light beams from the screens are reflected backward by the half mirror. A concave mirror is installed in the housing behind the half mirror, so that the image forming light beams from the half mirror are reflected forward by the concave mirror. The first and second display devices are positioned at laterally spaced positions in the housing, so that first and second virtual magnified images produced by the respective light beams from the concave mirror can be viewed or recognized from only two positions respectively.
