To observe an clearer and bigger image satisfactorily in an image display device with which observation by binocular vision is made.
In an image display device of this invention, an image display array 1 which is constituted by arranging, for example, minute pixels in two dimensions is provided, and these minute pixels are formed, for example, with light emitting elements having high directivity or display elements which are illuminated with transmission or reflection of illumination light having high directivity. Moreover, micro-lens arrays 2 in each of which one optical element is made to correspond respectively to each pair or set by making a pair in which these minute pixels are adjacent in a horizontal direction or a set in which a plurality these pairs are arranged in direction orthogonal to the horizontal direction an object are provided. Furthermore, one field lens 3 is provided to the whole of micro-lens arrays 2. Then, the virtual image 6 of the image display array 1 is formed by the micro-lens arrays 2 and the virtual image 6 is enlarged by the field lens 3, and the enlarged virtual image 5 of the image display array 1 is observed from eyes 4 of the observer.
