ABSTRACT:
Disclosed is a reflector for use in electro-optical displays utilizing electro-optical materials. The reflector is made from a composition comprising a blend of at least one alkali earth metal salt with a binder such as sodium carboxy methyl cellulose or thermoplastic phenoxy and an amount of solvent sufficient to provide suitable viscosity to permit the reflector to be deposited as a reflector on the display. The reflector composition comprises from about 30% to about 99.9% by weight of the alkali earth metal salt to the weight of binder casted to be adjacent to and directly adhered to the side of the back plate facing away from the electro-optical material and is able to provide a wide reflecting angle in conjunction with maintaining a high contrast ratio between the electrically energized state and the electrically un-energized state of the electro-optical material contained within the display.
