Abstract
A liquid crystal display device includes an illumination device, a light control element arranged at a projected light side of the illumination device, a reflective polarizer arranged at an upper portion of the light control element so that the transmission axis of polarized light is adjusted, a liquid crystal display element for controlling polarization of projected light projected from the reflective polarizer, and a screen arranged at an upper portion of the liquid crystal display element. The light control element includes an isotropic medium without birefringence.
