Abstract:
1. An image display device comprising: a lens array; and a scanner to two-dimensionally scan the lens array with a light beam for image display, wherein each of lenses of the lens array includes a convex surface with different curvatures in two directions orthogonal to an optical axis of the lens and to each other, in the lens array a shape of the lenses are a hexagon and the lenses are densely arranged, the shape of the hexagon is formed by extending an interval between a pair of opposing sides in a direction orthogonal to the opposing sides, the opposing sides among sides of the hexagon are most parallel to a direction in which the lens array is two-dimensionally scanned with the light beam, and X/Y=1, where X is a distance from a center of a lens to a midpoint of a border line between two neighboring lenses, and Y is a distance from the center of the lens to a top side or bottom side of the lens.
