摘要：A projection type liquid crystal display device using liquid crystal displayelements, which has a light source; illumination optics having a function of irradiating aplane to be irradiated with light emitted by the light source; and liquid crystal displayelements modulating light; projection optics for projecting light exiting from the liquidcrystal display elements; wherein the illumination optics include at least an elliptic mirrorand a spherical mirror, and the illumination optics include further a first lens array and asecond lens array, in which a plurality of lenses are arranged perpendicularly to an opticalaxis, from the light source side; and a condenser lens for irradiating the liquid crystaldisplay elements with light after exit from the second lens array with a high efficiency. Inthis way it is possible to realize a bright projection type liquid crystal display devicehaving a small size and a good image quality performance.
