In a display, an integrated repair structure for open lines of an active matrix array uses conducting repair elements with half-rings around the useful display region. Each repair element is assigned to the repair of only one group of lines of the array which cross the two open legs of the half-ring. An open line is then repaired by creating a connection at each of the two crossing points of this line with the two open legs of the half-ring of a repair element. The loop-closing is provided at least by the segment which connects the two open legs. The repair structure advantageously minimizes the stray couplings and the charge on the lines, and is inexpensive, while allowing a large number of lines to be repaired. It is especially suitable for large displays or high-resolution displays.
