Abstract
In a display device (1) with symmetrical two-pole switching elements (9) on a first substrate (active plate) damage due to electrostatic discharge of too high voltages across row electrodes (11) on a second substrate (passive plate) is prevented by arranging switching units (13) on the first substrate. The switching units are connected to the row electrodes (11) on the second plate via, for example an anisotropic conductor. Electrostatic discharge between column electrodes (8) and row and column electrodes is also prevented by arranging extra switching units (16, 26) on the active plate.
