Abstract: A display device comprising a display region on which a plurality of subpixels are arranged. The plurality of subpixels respectively comprise a transistor, a first organic insulating film, an inorganic insulating film, an electrode, and a second organic insulating film that covers an edge part of a first region in which a pattern of the electrode is formed. The inorganic film comprises an opening in a region that overlaps with the second region in which a pattern of the electrode is not formed in a planar view. The opening is formed in a middle between the first region of a first subpixel and the first region of a second subpixel or at a point located on the side closer to the first subpixel between the first region of the first subpixel and the first region of the second subpixel.
