NOVELTY - An electro-optical cell, in particular a liquid crystal display cell (2) or electrochemical photovoltaic cell, comprises: (a) a first front transparent substrate (4); (b) a second rear substrate (6) which may also be transparent; (c) the substrates are joined by a sealing frame delimiting a volume (8) for confining a sensitive substance with optical or electrical properties that can be modified; (d) the substrates incorporate electrodes (14, 16) destined to be connected to an power or control circuit. The sealing frame comprises a structured partition (12) on one of the substrates with its internal lateral surface delimiting the volume containing the sensitive substance. The substrates are assembled by a sealing joint (3) which occupies the interstice (28) delimited by the substrates and the outer lateral surface of the partition. The electrodes include bump contacts (20) of an electrical conducting material on the extension of each electrode at the point where they project from the partition to increase the surface of electrical contact with the power or control circuit.    USE - The invention is used for establishing an electrical connection between an electro-optical cell, such as a liquid crystal display cell or an electrochemical photovoltaic cell, and an electronic circuit.    ADVANTAGE - The invention allows the establishment of a reliable and non-cumbersome electrical contact between the electrodes of an electro-optical cell and a power or control circuit. The fabrication is easily carried out and risks of deterioration of the elements of the cell are limited.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the fabrication of this electro-optical cell.    DESCRIPTION OF DRAWING(S) - The drawing is a perspective view of an electro-optical cell conforming to the invention.
