1. A wind turbine rotor blade (10) having a pressure side, a suction side, a leading edge, and a trailing edge extending between a tip and a root, wherein the wind turbine rotor blade comprises a lightning protection device (84) and a leading edge member (70), the leading edge member (70) comprising:
an erosion shield (78, 80);
deicing means (118); and
an electrically conductive outer surface (80) which is operatively connected to the lightning protection device (84),
wherein the leading edge member (70) has a first region (78) extending in a spanwise direction and a second region (80) adjacent to the first region and extending in the spanwise direction,
wherein the second region (80) is closer to the tip than the first region (78),
wherein a boundary (79) between the first region (78) and the second region (80) extends in a chordwise direction,
wherein the first region (78) is composed of a different material than the second region (80), and
wherein the leading edge member (70) comprises a film layer comprising a metal material and a polymer layer, the film layer being bonded on top of the polymer layer, wherein the film layer forms part of the electrically conductive outer surface of the leading edge member (70).
