ABSTRACT:
A display device wherein a liquid crystal is contained between accurately spaced transparent electrical contacts to allow control over the transparency or transmissive properties of the display by application of a voltage to the contacts. In one version the spacing is provided by an inorganic frit of particles which occupy the space between the electrical contacts and impart a ground glass optical property. The particles provide accurate separation that prevents the contacts from short circuiting and when immersed in a liquid crystal give the display an overall transparent or other characteristic as desired. Preferably, the contacts are applied to glass substrates which are hermetically sealed by fusion of a denser glass frit applied between peripheral edges of the substrates. In a further version, spacing is provided by a set of legs perpendicularly emanating from one of the electrical contacts and supporting it from the other electrical contact.
