The dial with an enamel coating () includes a base plate () made of ceramic material with portions in relief () obtained by partial or through shaping or machining, formed by an insert () also having an enamel coating () and whose thickness defines a recess () or an embossment ().

Multi-stage enamelled dial

The present invention concerns a multi-layered cell, particular a liquid crystal display cell (), or an electrochemical photovoltaic cell, or a combination of a liquid crystal display cell and an electrochemical photovoltaic cell, this multi-layered cell comprising n superposed substrates (), n being an integer number greater than or equal to three, these substrates () being joined by sealing frames () delimiting (n&#x2212;1) sealed cavities () for containing an optically or electro-optically active medium, the upper surface () of the first substrate () and the lower surface () of the last substrate () forming the external faces of the cell (), said multi-layered cell () being characterised in that it includes (n&#x2212;1) filling holes () arranged, at least in part, on one side or other of the cell (), said (n&#x2212;1) filling holes () each communicating with a different cavity and passing through at least one cavity to reach the cavity with which they are connected, said (n&#x2212;1) filling holes () being isolated from the cavity or cavities through which they pass.

Multi-layered cell, particularly a liquid crystal display cell, or electrochemical photovoltaic cell

The present invention concerns a method for manufacturing a plurality of multi-layered cells, particularly liquid crystal display cells, or electrochemical photovoltaic cells, or a combination of such cells, each cell including at least two superposed sealed cavities each delimited by a sealing frame and filled with a liquid, this method comprising the step of collectively manufacturing a batch of cells including at least three plates common to all the display cells and connected to each other by patterns of sealing material connecting said plates to each other and forming the sealing frames which delimit the cavities of said cells, this method being characterised in that filling holes are pierced through the plates such that each of the cavities of a cell is fed by a different filling hole, each of the filling holes being in communication with at least two cells and feeding the cavities of the same level, i.e. comprised between the same two plates, or different levels of these at least two cells, said filling holes being isolated in a sealed manner from the cavities that they must not feed.

Method for manufacturing a batch of multi-layered cells, such as liquid crystal display cells, or electrochemical photovoltaic cells

The invention concerns a liquid crystal display cell including two close substrates ( ), separated by a sealing frame which delimits a sealed enclosure in which the liquid crystal molecules ( ) are confined, and spacers ( ) intended to maintain a constant spacing between said substrates ( ), characterised in that the sealing frame and/or the spacers ( ) are formed of an anisotropic polymer which is used to align and orient the liquid crystal molecules.
