According to one embodiment, an image display device having a display portion and a deflection element array. The display portion displays a display image including element images arranged in a first direction. The first deflection element array opposes to the element images. Each element image has element pixels having a width W in the first direction. The element pixels are arranged in the first direction and composing N rows. Each N row includes a plurality of the element pixels and arranged in a second direction orthogonal to the first direction. The element pixels of an i-th (1≦i≦N−1) row and the element pixels of an (i+1)th row are arranged such that a distance in the first direction between a first reference line along the second direction and a second reference line along the second direction is shifted by at least W/N.
