Abstract

A display device includes a substrate that includes a display area and a non-display area. A driver is disposed in the non-display area, and includes a driver circuit including a transistor and a driver control line transmitting a control signal to the driver circuit. A static electricity blocking line is disposed in the non-display area and circumscribes the display area. The static electricity blocking line at least partially overlaps the driver.

Claims (37)

1. A display device, comprising:

a substrate that includes a display area and a non-display area at least partially surrounding the display area;

a driver that is disposed in the non-display area, and includes a driver circuit including a transistor and a driver control line transmitting a control signal to the driver circuit; and

a static electricity blocking line that is disposed in the non-display area and circumscribes the display area,

wherein the static electricity blocking line at least partially overlaps the driver.

2. The display device of claim 1 , wherein the static electricity blocking line at least partially overlaps the driver circuit.

3. The display device of claim 1 , wherein the static electricity blocking line at least partially overlaps the driver control line.

4. The display device of claim 1 , further comprising a dam that is disposed in the non-display area and surrounds the display area, and at least partially overlaps the static electricity blocking line.

5. The display device of claim 4 , wherein a width of the static electricity blocking line is smaller than a width of a bottom surface of the dam, and the dam wholly covers the static electricity blocking line.

6. The display device of claim 4 , wherein the dam comprises a lower layer and an upper layer disposed on the lower layer, and wherein the static electricity blocking line is disposed between the lower layer and the upper layer.

7. The display device of claim 4 , wherein the static electricity blocking line is disposed in an upper portion the dam.

8. The display device of claim 4 , wherein a width of the static electricity blocking line is larger than a width of a bottom surface of the dam, and the dam covers a part of the static electricity blocking line.

9. The display device of claim 4 , further comprising a light emitting element disposed in the display area and including a first electrode, an emission layer disposed on the first electrode, and a second electrode disposed on the emission layer, wherein the second electrode extends to an area where the dam is located and covers an upper portion of the dam in the non-display area.

10. The display device of claim 9 , further comprising an encapsulation layer that covers the display area and seals the light emitting element, wherein the static electricity blocking line includes a plurality of static electricity blocking lines that extend in parallel with each other, and wherein at least a part of at least one of the plurality of static electricity blocking lines is covered by the encapsulation layer, and at least another part of the at least one of the plurality of static electricity blocking lines is not covered by the encapsulation layer.

11. The display device of claim 4 , wherein the static electricity blocking line comprises a plurality of static electricity blocking lines that extend in parallel with each other, and wherein the display device further comprises a connection line that connects the plurality of static electricity blocking lines with each other, and transmits a common voltage to the plurality of static electricity blocking lines.

12. The display device of claim 11 , further comprising a mask support and a distance between the mask support and the display area is larger than a distance between the dam in the non-display area and the display area, and the mask support at least partially overlaps only one of the plurality of static electricity blocking lines while circumscribing the display area.

13. A display device, comprising:

a first substrate including a display area and a non-display area at least partially surrounding the display area;

a plurality of transistors disposed on the first substrate;

a first electrode disposed on a first transistor of the plurality of transistors, in the display area, the first electrode being electrically connected with an electrode of the first transistor;

an emission layer disposed on the first electrode;

a second electrode disposed on the emission layer;

a contact layer that is disposed between the one electrode of the first transistor and the first electrode and is electrically connected to the one electrode of the first transistor and the first electrode; and

a static electricity blocking line that is disposed at a same layer as the contact layer in the non-display area, the static electricity blocking line surrounding the display area.

14. The display device of claim 13 , further comprising a driver that includes a driver circuit including a second transistor, of the plurality of transistors, disposed in the non-display area and a driver control line that transmits a control signal to the driver circuit, wherein the static electricity blocking line at least partially overlaps the driver.

15. The display device of claim 13 , further comprising a dam that is disposed in the non-display area and at least partially surrounds the display area, and at least partially overlaps the static electricity blocking line.

16. The display device of claim 15 , wherein a width of the static electricity blocking line is smaller than a width of a bottom surface of the dam, and the dam wholly covers the static electricity blocking line.

17. The display device of claim 15 , wherein a width of the static electricity blocking line is larger than a width of a bottom surface of the dam, and the dam covers a part of the static electricity blocking line.

18. The display device of claim 13 , wherein the second electrode extends to an area where the dam is located and covers an upper portion of the dam in the non-display area.

19. A display device, comprising:

a substrate including a display area and a non-display area at least partially surrounding the display area;

first to third concentric static electricity blocking lines that are disposed on the non-display area and each circumscribe the display area;

a first dam that is disposed in the non-display area and at least partially surrounds the display area, and at least partially overlaps the first static electricity blocking line;

a second dam that is disposed in the non-display area and at least partially surrounds the display area, and at least partially overlaps the second static electricity blocking line;

a mask support that is disposed in the non-display area and at least partially surrounds the display area, and at least partially overlaps the third static electricity blocking line; and

a connection line that connects the first to third static electricity blocking lines to each other, and transmits a common voltage to each of the first to third static electricity blocking lines.

20. The display device of claim 19 , further comprising: a light emitting element that is disposed in the display area; and an encapsulation layer that covers the display area, and seals the light emitting element, wherein the first static electricity blocking line and the second static electricity blocking line are covered by the encapsulation layer, and the third static electricity blocking line is not covered by the encapsulation layer.
