摘要：
A color wheel is fabricated with filter sectors formed on both surfaces of a substrate such that filter sectors adjacent to each other are disposed respectively on the top and bottom side surfaces of the substrate, whereby structures as means for demarcating each of the filter sectors can be shaped on the substrate at one time so that the adjacent filter sectors can be positioned with respect to each other with an accuracy of the demarcation of the structures without positioning masking jigs every time each filter is formed.
