Abstract
A projection type image display apparatus projects, under magnification by using a projection lens, image information carried by a luminous flux emitted from a ferroelectric liquid crystal display device. A field-sequential color-decomposing illumination optical system generates illumination color light for irradiating the ferroelectric liquid crystal display device. An analyzer and a quarter wave plate are arranged between the ferroelectric liquid crystal display device and the projection lens successively from the ferroelectric liquid crystal display device side.
