1. A liquid crystal glare-proof mirror that switches a non-glare-proof mode and a glare-proof mode and displays a picture thereon, comprising:

  • a first polarizing plate for selecting a polarization component to be transmitted through the first polarizing plate;

    a liquid crystal cell disposed on a back side of the first polarizing plate and having two control areas thereon, each of which is controlled independently;

    a second polarizing plate disposed on a back side of the liquid crystal cell, the second polarizing plate transmitting either of two orthogonal polarization components of light and reflecting the other of the polarization components; and

    an image generating apparatus disposed on a back of the second polarizing plate at a part corresponding to either of the two control areas, the image generating apparatus emitting the picture light having a polarization component which is transmitted through the second polarizing plate.
