PROBLEM TO BE SOLVED: To display an image stimulating high presence feeling for the viewer sitting on a back seat. SOLUTION: This image display system or the like is provided with a plurality of seats 1 placed in a plurality of rows, a concaved screen 2r placed in front of each seat 1, and a projecting device for projecting the image on the concaved screen 2r. A screen radius R which indicates a distance from a screen center G being a geometric center in relation to the arc of the concaved screen 2r to the concaved screen 2r is larger than the distance between the seat (I) of the center of a front row among respective seats 1 and the concaved screen 2r. Because the center of curvature G of the concaved screen 2r is placed far hehind than the seat (image center I) of the front row center, the presence feeling is secured even in the back seat.
