    The optical system comprises three reflection liquid crystal panels, polarization spliters PBS-R, PBS-G PBS-B which polarize components of an incident light to be reflected by the respective reflection liquid crystal panels, color separation and composition elements. The polarization splitters further separate the polarization converted output light in either an outputting direction or a non-outputting direction corresponding to the polarization, and the color separation and composition elements are arranged as separate elements in terms of optical path and in such a manner that these elements are disposed adjacent to each other in terms of space.
