Abstract
A method for manufacturing a reflective or transflective liquid crystal display device including a 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 under the front substrate, parallel to and at a distance from the latter, these two front and rear substrates being joined together with a sealing frame which delimits a sealed enclosure in which a liquid crystal composition is confined, the front and rear substrates being coated on the opposite faces thereof with electrically conductive transparent electrodes and counter-electrodes, the optical properties of the liquid crystal composition being changed by applying an electric field at the crossing point between an electrode and a corresponding counter-electrode.
