Abstract The display device (10) capable of irreversibly switching from a first indicating state to a second indicating state comprises a chamber (14) containing an electrolytic liquid (16) and having at least one exit opening (46), and at least two electrodes (22,24) located in said chamber (14) and in contact with said electrolytic liquid (16) as well as subjectable to electric voltage, wherein, upon application of electric voltage of a predetermined level to said electrodes (22,24), gas is generated in said chamber (14) causing the pressure within said chamber (14) to exceed a threshold value such that liquid (16) irreversibly exits said chamber (14) through said at least one exit opening (46) thereby switching from the first indicating state to the second indicating state.
