I was taxiing out from an Alpha gate in Frankfurt using my Ipad with the 10-9 page up to display the airport (flying First Officer (FO) had his 10-9 page up; the International Relief Officer (IRO) had the gate area chart up [10-9B]. We were given N7 to L to 25C. As we turned left onto L; ground informed us that we had taken N8 (between N and L). He said everybody gets this wrong and wondered if the Jeppesen pages were not correctly marked. On my 10-9 page none of the taxiways were marked; but after reviewing the gate charts we could see the N7 taxiway diverges to the left. The ground controller said it used to be a parking area and apparently still looks like one. He asked us to write this up as it is a problem for him every day; and maybe something could be done to fix it.
Air carrier Captain reports being cleared via N7; L to Runway 25C at EDDF; but not detecting that N7 jogs left at N and taking N8. EDDF Ground detects the error and states that it is common.
