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