Color wheel, manufacturing method of same, and color wheel assembly and image display apparatus incorporating same |
摘要 |
There is provided a method for manufacturing a color wheel which is structured such that plural kinds of filters functioning either to selectively transmit or to selectively reflect lights having respective different wavelength bands are formed on a disk-like substrate made of a light-transmittable material. The method comprises the steps of: forming a substrate assembly composed of the substrate and a rotary shaft disposed perpendicularly at the substrate; setting on the substrate assembly a masking jig provided with at least one opening to demarcate respective filters of the plural kinds, wherein the masking jig is positioned with reference to the rotary shaft; and forming the respective filters at the substrate assembly with the masking jig set on.
