Abstract
An image display device includes a light source, a flat display panel for forming an image in units of picture elements by using an incident light generated from the light source, and at least one double refraction plate for dividing the picture elements of the image formed by the flat display panel into duplication picture elements and shifting them to other positions independent of the original picture elements. The double refraction plate uses an amplitude division method to divide and shift the picture elements to a distance of 3/2P.sub.x, wherein P.sub.x is pitch between adjacent picture elements as displayed. An arrangement of two double refraction plates in sequence and an arrangement of three double refraction plates in sequence may be used to increase the picture elements four and eight times in number, respectively.
