Abstract: A three-dimensional image display device includes a display plate for producing light-emission or optical variations by an external electrical, magnetic, or optical operation, or a display member for arranging LEDs in matrix, a drive circuit for vibrating the display plate in a specified direction with respect to the display surface of the display plate, a shape data memory for storing two-dimensional sectional images for displaying on the display plate, through an input circuit, a position detector for detecting the position of the display plate while the display plate is vibrating, a controller for controlling so that a specified part of the display plate emits light or produces an optical variation for a specified time only, utilizing positional data from the position detector to display the two-dimensional sectional images on the display plate in sequence while the display plate is vibrating.
