Accordingly, the dummy area 121 which is not converted into the touch sensor panel can be minimized, so that the touch sensor cell 200 can be formed more than the same area of the ledge sheet 100, . On the other hand, when cutting the separator 110 for forming the touch sensor panel, the dummy area of the separated separator 110 is compensated for by using the protective film 410 including the dummy area 410 drawn out from the cut line side .
