Abstract: According to one embodiment, a first substrate includes a first area, a second area, a third area, a fourth area and a fifth area in a planar view. In the first substrate, an organic insulating film is present in the second and the third areas, is present neither in the third area nor in the fifth area, and forms an adjustment area. A conductive film is provided on the organic insulating film, the third area, the fourth area and a part of the fifth area. A sealing material is present in a part of the second area, the third area, the fourth area and a part of the fifth area to attach the first substrate and a second substrate. A through hole penetrates the first and the second substrates.

Abstract: 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.
