Abstract
An additional switching element (18) is associated with a switching element (8) in a display device (1), which additional switching element is short-circuited by a picture electrode (5) or row electrode (7) when the switching elements function normally, so that there is no voltage drop across the second switching element (18) when a pixel (11) operates satisfactorily. Consequently, the redundant element does not have any capacitive influence on the operation of the pixel or the transmission/voltage characteristic of the pixel. If the switching element (8) is defective, the second switching element (18) can be switched on.
