PROBLEM TO BE SOLVED: To obtain an image display device using lenticular lenses with, for example, a novel configuration which causes less faults.SOLUTION: In an image display device of an embodiment, a first lens member includes a plurality of first cylindrical lenses extending along a first direction and arranged in a second direction orthogonal to the first direction; and a plurality of first protruding parts protruding from between the two first cylindrical lenses adjacent to each other and extending along the first direction. A second lens member has a configuration identical to a configuration of the first lens member. The image display device is configured such that each of the plurality of first protruding parts is inserted between the two second cylindrical lenses adjacent to each other, a plurality of second protruding parts is overlapped one another in a state where each second protruding part is inserted between the two first cylindrical lenses adjacent to each other, and an image is visible through the first lens member and the second lens member.SELECTED DRAWING: Figure 1 |
