Patent ID: 7714857

Claim:
A method of manufacturing an apparatus for displaying a three-dimensional image observable in a viewing zone having a reference plane, comprising: forming a first film on one major surface of a glass substrate; applying a first resist onto the first film; patterning the first resist in accordance with a first optical opening and a marker; etching the first film; removing the first resist; attaching a seal to coat the marker; forming a second film on opposite surface of the glass substrate; applying a second resist onto the second film using the marker; removing the seal; patterning the second resist in accordance with a second optical opening; etching the second film and the marker; removing the second resist; wherein the apparatus includes: a display unit including pixels which are arranged in a matrix form, the pixels comprising sub-pixels disposed at a constant pixel pitch and grouped into first and second groups of sub-pixel arrays arranged along lines of sub-pixels, wherein each of the first groups of sub-pixel arrays has n number of sub-pixels, each of the second groups of sub-pixel arrays has (n+1) number of sub-pixels (n is a natural number), and the second groups of sub-pixel arrays are dispersedly allocated in an arrangement of the first groups of sub-pixel arrays along the lines of pixels; a display driver configured to display elemental images on sub-pixel arrays in the first and second groups of sub-pixel arrays, wherein the elemental images displayed on the first groups of sub-pixel arrays are produced from n parallax images, the n parallax images being displayed on a respective one of the n sub-pixels, the elemental images displayed on the second groups of sub-pixel arrays are produced from (n+1) parallax images, the (n+1) parallax images being displayed on a respective one of the (n+1) sub-pixels, and the parallax images embody views of the three-dimensional image from different directions; and a transmission control panel having optical openings arranged at a constant opening pitch and facing the first and second groups of pixel arrays, respectively, the transmission control panel being configured to control light rays emitted from the display unit so as to project the elemental images on the reference plane through the optical openings, respectively and the optical openings including the first optical opening and the second opening.
