Projection type image display apparatus
First Claim
1. A projection type image display apparatus which projects, under magnification by using a projection lens, image information carried by a luminous flux emitted from a reflection type image display device;
- wherein said reflection type image display device is a ferroelectric liquid crystal display device;
wherein said apparatus comprises a field-sequential color-decomposing illumination optical system for generating illumination color light for irradiating said ferroelectric liquid crystal display device; and
wherein an analyzer and a quarter wave plate are arranged between said ferroelectric liquid crystal display device and said projection lens successively from said ferroelectric liquid crystal display device side.

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.
