PURPOSE: A lens array sheet equipped with a light transmission adjusting filter is provided to improve the clearness of a three dimensional images. CONSTITUTION: A lens array layer is composed of repeated convex lenses(41, 49) and light transmittance adjusting filters(44, 45). Focus distance layers(47, 48) are formed on the lower side of the lens array layer. A three dimensional layer(51) is formed on the lower side of the focus distance layers. The sizes of the light transmittance adjusting filters are smaller than those of the convex lenses and suppresses the arrival of light to the three dimensional layer.
