PROBLEM TO BE SOLVED: To install an indicator at any arbitrary position so as to be easily recognized as a spatial information indicator by transmitting light emitted from a light source through a transmission indicator original, forming the image of this transmitted light on a non-spherical mirror and displaying the indicator at a virtual display position. SOLUTION: A system is composed of an information display device 1, pixel display 2, non-spherical mirror 3 installed on the pixel display 2, light source 4 installed on the pixel display 2, and transmission indicator original 5 installed on the pixel display 2. Then, the pixel displays 2 more than plural are used and since the transmission indicator original 5 is irradiated on the non-spherical mirror 3 by the light source 4, the respective pixel indicators 2 combine and form images similar to the transmission indicator original 5 in the space. In this case, on the other hand, arbitrary indicator information can be displayed by changing the transmission indicator original 5. Thus, light radiated from the light source 4 is transmitted through the transmission indicator original 5, the image of this transmitted light is formed by the non-spherical mirror 3, and the indicator is displayed at the virtual display position.
