First claim

What is claimed is:

1. A display device comprising:
a first substrate;
a second substrate including a transparent conductive film;
an optical element adhered to the transparent conductive film; and
a connecting member, wherein
the first substrate includes a first region which overlaps the second substrate and includes a display portion, and a second region including an electrode,
the second substrate includes a substrate edge located at a boundary between the first region and the second region and extending along a first direction,
the optical element includes an optical element edge located between the display portion and the substrate edge in a second direction intersecting the first direction,
a whole of the optical element edge does not overlap the substrate edge in a plan view,
the transparent conductive film includes an extended portion extending from the optical element edge toward the substrate edge,
the connecting member is in contact with the substrate edge and electrically connects the electrode and the extended portion,
the optical element includes a notch set back from the optical element edge,
the notch and the connecting member are arranged in the second direction, and
a width of the connecting member along the second direction at a position overlapping the extended portion, is less than a width of the extended portion along the second direction.

2. The display device according to claim 1 , wherein
the optical element includes a polarizer having a polarization axis, and
the notch and the connecting member are arranged in a direction intersecting the polarization axis.

3. The display device according to claim 1 , wherein
the second substrate includes a light-shielding layer that surrounds the display portion, and
the notch overlaps the light-shielding layer in the plan view.
