Abstract
In order to realize liquid crystal display devices having a wide viewing angle and reduce the absorption loss by polarizers and color filters, and arrangement of reflective color selective means, reflective polarizing selective means, a light control element, and others are specified. The liquid crystal display device able to produce a display of high performance and improved brightness is formed of liquid crystal display elements 20 for controlling polarizing light so that the major axis direction of a pixel is arranged approximately in parallel with a direction wherein the linearly polarized light component of the projected light projected from said illumination device is high; an illumination device 50 arranged at a rear plane of the liquid crystal display element; a reflector 54 arranged at a rear plane of the illumination device; light control elements 40 and reflective polarizing selective means 30 arranged between the liquid crystal display element and the illumination device; and a screen arranged at an opposite side relative to the illumination device of the liquid crystal display element.
