Abstract
A colored light separating device and a single-panel color image display apparatus using the same include a colored light separator having a plurality of dichroic filters to separate incident light into a plurality of colored light beams and a driving device which moves the colored light separator to scroll the separated colored light beams. The colored light separating device performs color scrolling by driving the colored light separator itself so that the structure of the colored light separating device enabling color scrolling is simplified, continuity and consistency of the color scrolling are guaranteed, and the scrolling speed of color bars are kept constant.
