1. 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, said method comprising the steps of collectively manufacturing a batch of cells including at least three plates common to all the display cells and connected to each other by matrices of sealing material connecting said plates to each other and forming the sealing frames which delimit the cavities of said cells, wherein the method further comprises the step of piercing filling holes 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 one cavity of at least two cells and feeding the cavities of the same level, said filling holes being isolated in a sealed manner from the cavities that each said filling hole is not in communication with, such that said cavities which are not in communication with the respective filling holes are not filled.
