摘要： According to one embodiment, an image display apparatus includes a light source, a modulation unit, a first array and a second array. The modulation unit modulates intensity and a color of the light to generate beams corresponding to each of modulated pixels included in a modulated pixel group. The first array is formed by juxtaposing a plurality of first deflection elements each having a generating line parallel to a vertical direction of the modulated pixels. The second array is formed by juxtaposing a plurality of second deflection elements each having a generating line tilted by an angle represented by tan−1(α×m/n) with respect to a generating line of the first deflection element.
