Abstract (en)
A display apparatus utilizing afterimage comprises a plurality of display boards disposed alongside a track of vehicles at such intervals that a passenger in a running vehicle can see the character or pattern on the display boards in a continuous flow by the action of afterimage. Shielding means having a vertical slit is provided at a distance away from the display surface of each display board to cover the display surface. A passenger in a running vehicle sees one display board after another disposed alongside the track through the slit cut in the shielding means as the vehicle moves forward. Because adjoining display surfaces are kept from overlapping, the passenger can clearly see the character or pattern that appears to remain at a standstill or moving.
