ABSTRACT:
A picture display apparatus is provided with a display device having pixels disposed in a mosaic pattern. A plurality of optical filter surfaces are respectively placed between the display device and a viewer so that both surfaces can be overlapped with each other. Each pixel in the display device is diffracted or refracted by both surfaces to become a plurality of pixels. For each optical filter surface, an element for diffusion such as a diffraction grating and an element for refraction such as a prism can be utilized for the diffraction and refraction.
