The invention provides an optical component and a projector in which a light modulation device is reliably fixed relative to a prism, and in which the size of the prism can be reduced to the minimum size required from an optical point of view. Frame members are attached to a cross-dichroic prism, and retaining frames, which retain liquid crystal panels, are fixed to the frame members with fixing pins. Since it is not necessary to fix the fixing pins directly to the cross-dichroic prism, the cross-dichroic prism, having the minimum size required from an optical point of view, may be used. In addition, since a large fixing area is provided between the frame members and the fixing pins, the frame members and the fixing pins are fixed to each other with sufficient fixation strength. Accordingly, the liquid crystal panels may be reliably fixed relative to the cross-dichroic prism.
