Abstract

The disclosed display device includes: a substrate; a gate electrode disposed on the substrate, wherein a first projection is defined by projecting the gate electrode on the substrate; and a connecting member disposed on the gate electrode and electrically connecting to the gate electrode, wherein a second projection is defined by projecting the connecting member on the substrate, an overlapping region is defined as a region of the second projection overlapping the first projection, and an area of the first projection is greater than an area of the overlapping region.

Claims (30)

1. A display device, comprising:

a substrate;

a gate electrode disposed on the substrate, wherein a first projection is defined by projecting the gate electrode on the substrate;

at least one data line disposed on the substrate and extending along an extension direction; and

a connecting member disposed on the gate electrode and electrically connecting to the gate electrode, wherein the connecting member comprises a first terminal part and a middle part, the middle part is connected to the first terminal part, and a maximum width of the middle part in a direction perpendicular to the extension direction is less than a maximum width of the first terminal part in the direction,

wherein a second projection is defined by projecting the connecting member on the substrate, an overlapping region is defined as a region of the second projection overlapping the first projection, and an area of the first projection is greater than an area of the overlapping region.

2. The display device of claim 1 , further comprising an insulating layer disposed between the first terminal part and the gate electrode, wherein a contact via penetrates the insulating layer, and the first terminal part electrically connects to the gate electrode through the contact via.

3. The display device of claim 2 , wherein the connecting member further comprises a second terminal part, the middle part is located between the first terminal part and the second terminal part, the second terminal part is relatively away from the contact via in the extension direction, and the maximum width of the middle part in the direction is less than a maximum width of the second terminal part in the direction.

4. The display device of claim 1 , further comprising a metal layer disposed between the gate electrode and the connecting member, wherein the metal layer includes an opening, and the maximum width of the first terminal part in the direction is less than a maximum width of the opening in the direction.

5. The display device of claim 4 , wherein a third projection is defined by projecting the metal layer on the substrate, and an area of the third projection is greater than the area of the first projection.

6. The display device of claim 5 , wherein in a top view of the display device, the third projection partially overlaps the first projection.

7. The display device of claim 1 , wherein the first projection comprises a first outline, the second projection comprises a second outline, the first outline crosses the second outline at a first intersection and a second intersection, and a distance between the first intersection and the second intersection is greater than the maximum width of the middle part in the direction.

8. The display device of claim 1 , further comprising a power supply circuit disposed on the substrate, wherein the connecting member is located adjacent to the power supply circuit.

9. The display device of claim 8 , wherein in a top view of the display device, the first projection partially overlaps the power supply circuit.

10. The display device of claim 1 , wherein the connecting member includes a curved edge.

11. A display device, comprising:

a substrate;

a gate electrode disposed on the substrate;

at least one data line disposed on the substrate and extending along an extension direction; and

a connecting member disposed on the gate electrode and electrically connecting to the gate electrode, wherein the connecting member comprises a first terminal part and a middle part, the middle part is connected to the first terminal part, and a maximum width of the middle part in a direction perpendicular to the extension direction is less than a maximum width of the terminal part in the direction,

wherein in a top view of the display device, the connecting member partially overlaps the gate electrode.

12. The display device of claim 11 , further comprising an insulating layer disposed between the first terminal part and the gate electrode, wherein a contact via penetrates the insulating layer, and the first terminal part electrically connects to the gate electrode through the contact via.

13. The display device of claim 12 , wherein the connecting member further comprises a second terminal part, the middle part is located between the first terminal part and the second terminal part, the second terminal part is relatively away from the contact via in the extension direction, and the maximum width of the middle part in the direction is less than a maximum width of the second terminal part in the direction.

14. The display device of claim 11 , further comprising a metal layer disposed between the gate electrode and the connecting member, wherein the metal layer includes an opening, and the maximum width of the first terminal part in the direction is less than a maximum width of the opening in the direction.

15. The display device of claim 14 , wherein a first projection is defined by projecting the gate electrode on the substrate, a third projection is defined by projecting the metal layer on the substrate, and an area of the third projection is greater than an area of the first projection.

16. The display device of claim 15 , wherein in the top view of the display device, the third projection partially overlaps the first projection.

17. The display device of claim 15 , wherein the first projection comprises a first outline, the second projection comprises a second outline, the first outline crosses the second outline at a first intersection and a second intersection, and a distance between the first intersection and the second intersection is greater than the maximum width of the middle part in the direction.

18. The display device of claim 15 , further comprising a power supply circuit disposed on the substrate, wherein in a top view of the display device, the first projection partially overlaps the power supply circuit.

19. The display device of claim 11 , further comprising a power supply circuit disposed on the substrate, wherein the connecting member is located adjacent to a power supply circuit.

20. The display device of claim 11 , wherein the connecting member includes a curved edge.
