VERBINDUNGSMITTEL ZUM EINRICHTEN EINER ELEKTRISCHEN VERBINDUNG ZWISCHEN EINER ZELLE, INSBESONDERE EINER FLÜSSIGKRISTALLZELLE, UND EINER STROMVERSORGUNGS- ODER STEUERSCHALTUNG

摘要

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. An Independent claim is also included for the fabrication of this electro-optical cell.
