Abstract
A wiring circuit substrate comprises first circuit element means one one side of the substrate connected to electrode lines of X-Y matrix electrodes, respectively, and second circuit element means in the symmetrical position of the first circuit element means on the other side of the substrate connected to the electrode lines of the X-Y matrix electrodes, respectively, wherein each of leads of the first and the second circuit element means is connected to the output and input lines of the X-Y matrix electrodes via through holes, respectively. The first circuit element comprises integrated transisitors for driving the X-Y matrix electrodes. The second circuit element comprises integrated diodes for protecting an overcurrent in the X-Y matrix electrodes.
