1. An in-plane switching type liquid crystal display device comprising:
an active element substrate;
an opposing substrate arranged on the active element substrate; and
a liquid crystal layer arranged between the active element substrate and the opposing substrate,
wherein
said active element substrate has:
a substrate;
a wiring that is arranged on the substrate and has a part extending in a first direction parallel to the surface of the substrate and another part extending in a second direction parallel to the surface of the substrate and different from the first direction;
a convex-shaped insulation film that is arranged so as to cover the wiring and has a part extending in the first direction and another part extending in the second direction;
an electrode that is arranged on the insulation film and has a part extending in the first direction and another part extending in the second direction; and
an oriented film arranged on the electrode, for allowing the liquid crystal layer to be oriented, and
said opposing substrate has a shielding layer that is formed in a region including the entire region directly over the insulation film and in a region positioned inside the region directly over the electrode.
