Abstract
This invention is directed to liquid crystal mixtures which have an extended operating range and require a low operating voltage. They are white in color and stable to atmospheric oxygen, moisture, and light. Because of their superior properties, they are useful in electro-optical displays, especially in liquid crystal watches and pocket-size calculators.
