Abstract
The image display device () provides images perceivable from the area of the eye box (E), and includes a light source unit (), a screen (), a scanning unit () and an optical system (). The screen () has a single micro lens array () on which multiple micro lenses () are arranged. The scanning unit () includes a mirror () to reflect beams emitted from the light source unit (), and swings the mirror () around a pivot center () to scan the beams thereover, thereby generating images. The optical system () brings the images formed on the screen () to the eye box (E). An angle (θ) formed between a zero-order diffracted beam and a first-order diffracted beam, which are among a luminous flux of beams diffracted by the screen () and pass through the center of the eye box (E), is smaller than a minimum visual angle (V).
