Abstract

An electro-optical display cell including: a transparent front substrate whose top surface forms the front face of the cell; a back substrate whose lower surface forms the back face of the cell; a sealing frame joining the front and back substrates and defining a volume for retaining an electro-optically or photo-electrically active medium; the front and back substrates including on faces opposite to each other at least one electrode, each connected by conductive paths to an electrical power or control circuit and defining lateral electric contact zones, wherein the conductive paths are each formed of a first part in contact with the electrodes at the level of the lateral electric contact zones, and a second part extending over the back surface, contact means arranged over the edge and/or the back of the cell forming the electrical junction between the first and second parts of the conductive paths.
