According to one embodiment, a display device includes a first substrate including a first area, a second area, a third area and a fourth area from an end portion to an inner side in a planar view. An organic insulating film is present in the second area and the third area, and is not present in the fourth area. A conductive film is formed at least on the organic insulating film of the second area. A sealing material is present in the first area, the third area and the fourth area to attach the first substrate and a second substrate. A through portion is adjacent to an inner side of the fourth area and penetrates the first substrate, the second substrate and the sealing material.
