Abstract
A liquid crystal display comprising a glass substrate and an opaque ceramic substrate both provided with electrodes, and a nematic liquid crystal contained in the gap between the substrates, in which the orientation of the nematic liquid crystal molecules is controlled by applying an electric voltage between the electrodes to achieve colored display against the color of the ceramic substrate.
