Abstract
A composite liquid crystal electroluminescent electro-optical display device utilizing single-cell construction. Backlighting is furnished by a low-intensity, low-power-consumption integrally formed electroluminescent light source cooperating with a liquid crystal element with commonly excited electrodes. The integral electro-luminescent light source replaces the requirement for a transflector. The invention offers substantially improved contrast while minimizing physical size, power dissipation and construction complexity.
