1. A projection type liquid crystal display comprising:

  • an optical source for generating light;

    a light dividing means which divides the light into a first light having a first polarization direction and a second light having a second polarization direction, and allows the first and second lights to come out in different directions from each other;

    a pair of reflective liquid crystal display elements formed of a first reflective liquid crystal display element and a second reflective liquid crystal display element, each of the pair of reflective liquid crystal display elements including a pair of substrates facing each other and liquid crystal sealed between the pair of substrates, the first reflective liquid crystal display element changing the first polarization direction of the first light by the liquid crystal sealed therein to allow the first light to come out thereof, and the second reflective liquid crystal display element changing the second polarization direction of the second light by the liquid crystal sealed therein to allow the second light to come out thereof;

    a driving means for driving the first reflective liquid crystal display element and the second reflective liquid crystal display element with synchronization;

    a light synthesizing means for receiving the first light which comes out of the first reflective liquid crystal display element and the second light which comes out of the second reflective liquid crystal display element, and synthesizing the first and second lights into image light; and

    a screen on which the image light is displayed.
