Zusammenfassung:	Provided is a technology for preventing current leak of a charge holding capacitor which constitutes a pixel of a display device so as to prevent deterioration of display image quality of the display device. The display device includes a first contact hole connecting a first wiring layer and a second wiring layer which is formed over the first wiring layer, a second contact hole connecting the second wiring layer and a third wiring layer which is formed over the second wiring layer, and an electrode layer formed between the plurality of insulating films disposed between the second wiring layer and the third wiring layer, wherein at a position in a substrate surface direction, a distance between a electrode layer and the second contact hole is larger than a distance between the electrode layer and the first contact hole.
