Abstract: According to one embodiment, a display device includes a first insulating substrate including a first substrate end, a second insulating substrate including an outer surface and a second substrate end, an electrode located between the first substrate end and the second substrate end, and a transparent conductive layer disposed on a side on which the outer surface is located. The outer surface includes a flat portion and a sloping portion. A thickness on a side on which the second substrate end is located is less than a thickness on a side on which the flat portion is located. The transparent conductive layer overlaps the sloping portion and is electrically connected to the electrode.
