1. A display device comprising:
an insulative substrate;
a first inorganic insulation film above the insulative substrate;
an organic insulation film stacked on the first inorganic insulation film;
a second inorganic insulation film stacked on the organic insulation film;
a third inorganic insulation film stacked on the second inorganic insulation film;
a plurality of pixel electrodes; and
a common electrode opposed to the plurality of pixel electrodes; wherein
the insulative substrate includes a substrate end portion,
the organic insulation film includes an end face located around the substrate end portion,
the first inorganic insulation film is exposed from the organic insulation film at a region between the end face and the substrate end portion,
a first part of the second inorganic insulation film contacts the end face of the organic insulation film,
a second part of the second inorganic insulation film contacts the first inorganic insulation film at the region between the end face and the substrate end portion,
a third part of the third inorganic insulation film contacts the first part of the second inorganic insulation film, and
a fourth part of the third inorganic insulation film contacts the second part of the second inorganic insulation film at the region between the end face and the substrate end portion.
