Abstract
A method for embodying a display cell with a counter-electrode contact pickup. Contact blocks 12 are separated from counter-electrode contacts 20 by passivation film 22. The electrodes linked between the counter-electrode and the contacts 20 are obtained by calcining the glue of the blocks so as to render them conductive by using a laser beam 30. In addition, the passivation film 22 is perforated by using the laser beam 30. This method finds particular application in the embodiment of liquid crystal display screens.
