A method for manufacturing a plurality of electro-optic cells is disclosed, in particular for manufacturing liquid crystal display cells (2) or photovoltaic cells, each cell including a cavity (5) filled with a liquid and defined by sealed partitions (8, 9) between two plates (3, 4), in particular made of glass, provided with electrodes within the cavity. In a first step, a batch of cells (2) is manufactured, whose cavities are filled with the desired liquid and sealed. In a second step, the external contour (20) of each cell is cut, and if necessary a hole (10) passing through the cell, by means of a very high pressure water jet (30), the water either being loaded or not with an abrasive agent. Thus, the external layers (25, 26) such as a polarizer and a reflector may be applied onto the batch prior to the cutting step.
