Abstract
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.
