Patent Images
1. A liquid crystal device comprising:
- a front transparent substrate, a rear substrate, and a crystal material therebetween, a transparent first electrical conductor on said front substrate, a laminate disposed on said rear substrate and comprising, in the named order towards said front substrate, a light reflector for reflecting light in the direction of said front substrate, a thin film insulator, and a second electrical conductor, at least portions of said first and second conductors overlapping one another.

Abstract
The device comprises a front transparent substrate having a transparent electrode on the inner surface thereof, a rear substrate, and a liquid crystal material disposed between the two substrates. The inside surface of the rear substrate is covered with a light-reflecting material, e.g., silver, covered in turn with a thin layer of dielectric material, e.g., silicon dioxide. Disposed on the dielectric layer is a patterned electrode of either a transparent material, e.g., tin oxide, or a lightreflecting material, e.g., silver.
