Abstract
A method of fabricating a liquid crystal display device including a reflective or transflective liquid crystal cell whose liquid crystal molecules are aligned in a planar or vertical manner, this liquid crystal cell being formed of a transparent front substrate located on the side of an observer, and a rear substrate, also transparent, which extends beneath the front substrate, parallel to and at a distance from the latter, these two front and rear substrates being joined to each other with a sealing frame which defines a sealed enclosure in which a liquid crystal composition is confined, the front and rear substrates being coated on their opposite faces with electrically conductive transparent electrodes and counter-electrodes, the optical properties of the liquid crystal composition being modified by application of an electric field at the point of intersection between an electrode and a corresponding counter-electrode.
