Image display apparatus

An image display apparatus, comprising:

• a light source emitting light;
• a modulation unit configured to modulate an intensity of the light and a color of the light to generate beams corresponding to each of modulated pixels included in a modulated pixel group, the modulated pixels each being determined by an observation position where an image is observed and an output angle corresponding to the observation position, the modulated pixel group being the modulated pixels arrayed two-dimensionally;
• a first array formed by juxtaposing a plurality of first deflection elements each having a generating line parallel to a vertical direction of the modulated pixels and configured to deflect the beams for each first modulated pixel group corresponding to m columns in the modulated pixel group to generate a first deflected beams, them being a natural number;
• and
• a second array 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 and configured to deflect the first deflected beams for each second modulated pixel group corresponding to n rows in the first modulated pixel group to generate a second deflected beams, the a being a ratio of a horizontal pixel interval to a vertical pixel interval of each modulated pixel, the n being a natural number.
