LIQUID CRYSTAL GLARE-PROOF MIRROR
First Claim
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.

Abstract
Disclosed is a liquid crystal glare-proof mirror 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.
