PROBLEM TO BE SOLVED: To provide a display apparatus that can accomplish displaying of photo-images on the displaying face to give an impression of depth.SOLUTION: A display apparatus comprises an irradiating light source, a display board 30 and a projecting member. On the display face 30a of the display board 30, a plurality of reflective face parts 34 whose extending direction is aligned to the circumferential direction CD are so formed as to be arrayed in the diametric direction RD. On the projecting member, a plurality of ejection faces that are arranged in the circumferential direction CD with gaps between them and eject light from the irradiating light source toward each reflective face part 34 are formed. By the light ejected by each ejection face in the diametric direction RD, a linearly extending optical image is projected on the display face 30a. And each reflective face part 34 is concavely curved in a direction away from each ejection face, and the curvature 1/R of the curve in each reflective face part increases as its distance from each ejection face in the diametric direction RD increases. |
