Filed: 1991-12-27
Abstract: PURPOSE:To attain the variable display of large area on a direction-selective transparent member by making information display light incident on the direction-selective transparent member and forming the real image of information on the direction-selective transparent member. CONSTITUTION:This display device uses the direction-selective transparent member 1 which scatters and transmits incident light from a specific direction and also transmits incident light from a direction different from the specific direction as it is. The information display light L which is emitted from an optical information display means D is made incident on the direction-selective transparent member 1 from the specific direction through an optical member A. Further, the optical member A forms the real image of the information on the direction-selective member 1. The real image of the information formed on this direction-selective transparent member 1 is emitted as scattered light from the opposite outgoing-side flank of the direction-selective member 1 from the incoming side. Therefore, when the direction-selective transparent member 1 is viewed from a specific position on the outgoing-side flank, the display information can be seen on a scene in a direction different from the specific direction of the incoming side.
