Planar heater for liquid crystal element
First Claim
1. A planar heater directly affixed to one major surface of a liquid crystal element characterized in that a very thin highly flexible metal plate having a relatively high specific resistance is subjected to etching-working to form a mesh-like heat generating body, opposite ends of which are provided with terminal portions for connection into an electrical circuit;
- said mesh-like heat generating body and a permeable reflecting plate being laminated together by an ultraviolet hardening type adhesive to provide an integral configuration which is positioned adjacent said liquid crystal element.

Abstract
A planar heater for a liquid crystal element includes a thin metal plate having a relatively high specific resistance such as stainless, nichrome, nickel-chrome iron alloy, etc. The thin metal plate is subjected to etching-working to form a mesh-like heat generating body, opposite ends of which are provided with terminal portions for connection into an electrical circuit.
