1. A liquid crystal display device, comprising:

  • a liquid crystal panel including (1) a first substrate having first transparent electrodes provided in a form of matrix, (2) a second substrate, having second transparent electrodes, provided so as to face the first substrate, and (3) a liquid crystal layer sandwiched between the first substrate and the second substrate;

    a polarizing plate-equipped semitransmitting reflecting plate provided on a side opposite to a displaying surface of said liquid crystal panel; and

    illuminating means for illuminating said liquid crystal panel through said polarizing plate-equipped semitransmitting reflecting plate,wherein said liquid crystal panel includes active elements which control supplying of a charge to the first transparent electrodes by their switching, and reflectance and transmittance of said polarizing plate-equipped semitransmitting reflecting plate are set so as to make contrast of said liquid crystal panel higher when said illuminating means is not lighted than when said illuminating means is lighted.
