Abstract

According to one embodiment, a display device includes a first substrate including an electrode, a second substrate including a substrate edge, a transparent conductive film including an extended portion, an optical element adhered to the transparent conductive film, and a connecting member. The connecting member is in contact with the substrate edge and electrically connects the electrode and the extended portion. The optical element includes a penetration portion. The penetration portion and the connecting member are arranged in a direction intersecting an extending direction of the substrate edge.

Claims (42)

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,

the optical element edge is formed in a linear shape extending along the first direction,

a length of the optical element edge is greater than a width of the display portion in the first direction,

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 penetration portion, and

the penetration portion and the connecting member are arranged in the second direction.

2. The display device according to claim 1 , wherein the penetration portion is an opening or a cut line, and

the penetration portion is located between the display portion and the optical element edge in the second direction and is away from the optical element edge.

3. The display device according to claim 2 , wherein the penetration portion extends along the substrate edge.

4. The display device according to claim 3 , wherein a length of the penetration portion along the substrate edge is longer than a length of the connecting member overlapping with the extended portion along the substrate edge.

5. The display device according to claim 2 , wherein the penetration portion extends along a direction intersecting the substrate edge.

6. The display device according to claim 1 , wherein

the optical element includes a polarizer having a polarization axis, and

the penetration portion and the connecting member are arranged in a direction intersecting the polarization axis.

7. The display device according to claim 1 , wherein

the second substrate includes a light-shielding layer that surrounds the display portion, and

the penetration portion overlaps the light-shielding layer.

8. A display device comprising:

a first substrate;

a second substrate including a transparent conductive film;

an optical sheet on 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 which does not overlap the second substrate and is adjacent to the first region,

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 sheet includes an optical sheet edge located between the display portion and the substrate edge in a second direction intersecting the first direction,

the optical sheet edge is formed in a linear shape extending along the first direction,

a length of the optical sheet edge is greater than a width of the display portion in the first direction,

the transparent conductive film includes an extended portion extending from the optical sheet edger toward the substrate edge,

the connecting member is in contact with the substrate edge and electrically connects the extended portion and an electrode on the first substrate,

the optical sheet includes a penetration portion, and

the penetration portion and the connecting member are arranged in the second direction.

9. The display device according to claim 8 , wherein the optical sheet is a polarizer.

10. The display device according to claim 8 , wherein the penetration portion is an opening or a cut line, and

the penetration portion is located between the display portion and the optical sheet edge in the second direction and is away from the optical sheet edge.
