ABSTRACT:
A liquid crystal glare-proof mirror is capable of displaying a picture in which a non-glare-proof mode and a glare-proof mode is switched, including a first polarizing plate for selecting a polarization component to be transmitted; a liquid crystal cell disposed at a back of the first polarizing plate, the liquid crystal cell having two control areas, each of which is controlled independently; a second polarizing plate disposed at a back of the liquid crystal cell, the second polarizing plate transmitting either one of two orthogonal polarization components of light and reflecting the other one of the polarization components; and an image generating apparatus disposed at a part of a back of the second polarizing plate, the part corresponding to either one of the two control areas, the image generating apparatus ejecting picture light having a polarization component which is transmitted through the second polarizing plate.
