This image display apparatus is constituted by a projector20and a decorative display unit10comprising a light transmitting substrate having multiple colored dots arranged on one surface of the substrate and multiple light transmitting light converging elements arranged on the other surface of the substrate, at least a part of which is provided with an image formation means for forming an image from light projected from the projector20.With this image display apparatus, a virtual image of the dots is formed on a plane different from the plane of the image projected on the image formation means to provide a three-dimensional-like visual effect. It is preferred that directivities of the arrangements of the dots and light converging elements of the decorative display unit10are identical to each other, and pitches thereof are different from each other.
