Abstract

A display device includes a circuit board connected to one side of the first panel, wherein the circuit board includes a first pad, and a second pad adjacent to the first pad in a first direction, wherein the circuit board has a first side adjacent to the first panel, wherein the first pad and the second pad have a predetermined length in a second direction intersecting the first direction, wherein a pitch between the first pad and the second pad varies along the second direction from the first side surface of the circuit board.

Claims (38)

1. A display device comprising:

a first panel; and

a circuit board connected to one side of the first panel,

wherein the circuit board comprises:

a first pad; and

a second pad adjacent to the first pad in a first direction,

wherein the circuit board has a first side adjacent to the first panel,

wherein the first pad and the second pad have a predetermined length in a second direction intersecting the first direction,

wherein a pitch between the first pad and the second pad varies along the second direction from the first side of the circuit board.

2. The display device of claim 1 , wherein the pitch between the first pad and the second pad increases as a distance increases from a first side surface at the first side of the circuit board in the second direction.

3. The display device of claim 1 , wherein the pitch between the first pad and the second pad gradually increases moving away from a first side surface at the first side of the circuit board in the second direction.

4. The display device of claim 1 , wherein a second pitch at a second point between the first pad and the second pad is greater than a first pitch at a first point, wherein the first point is closer to a first side surface at the first side of the circuit board than the second point.

5. The display device of claim 1 , wherein a first width of the first pad is greater than a second width, and the first width of the first pad is closer to a first side surface at the first side of the circuit board than the second width.

6. The display device of claim 1 , wherein a first width of the second pad is greater than a second width, and the first width of the second pad is closer to a first side surface at the first side of the circuit board than the second width.

7. The display device of claim 1 , wherein the first pad is an alignment pad, and the second pad is a signal pad.

8. The display device of claim 1 , wherein the first panel is an input sensing panel including sensing electrodes.

9. The display device of claim 8 , wherein the input sensing panel comprises a sensing pad,

wherein the second pad is electrically connected to the sensing pad.

10. The display device of claim 9 , further comprising an anisotropic conductive film electrically connecting the sensing pad and the second pad.

11. A display device comprising:

a display panel including pixels;

an input sensing panel on an upper surface of the display panel and including a sensing electrode and a sensing pad electrically connected to the sensing electrode; and

a circuit board connected to one side of the input sensing panel,

wherein the circuit board comprises:

a first pad; and

a second pad adjacent to the first pad in a first direction and electrically connected to the sensing pad,

wherein the circuit board has a first side adjacent to the input sensing panel,

wherein the first pad and the second pad have a predetermined length in a second direction intersecting the first direction,

wherein a pitch between the first pad and the second pad varies along the second direction from the first side of the circuit board.

12. The display device of claim 11 , further comprising an optical member on the input sensing panel.

13. The display device of claim 12 , wherein a first side surface at the first side of the circuit board is spaced apart from the optical member by a predetermined distance.

14. The display device of claim 11 , wherein the pitch between the first pad and the second pad gradually increases moving away from a first side surface at the first side of the circuit board in the second direction.

15. The display device of claim 11 , wherein the pitch between the first pad and the second pad gradually increases moving away from a first side surface at the first side of the circuit board in the second direction.

16. The display device of claim 11 , wherein a second pitch at a second point between the first pad and the second pad is greater than a first pitch at a first point, wherein the first point is closer to a first side surface at the first side of the circuit board than the second point.

17. The display device of claim 11 , wherein a first width of the first pad is greater than a second width, and the first width of the first pad is closer to a first side surface at the first side of the circuit board than the second width.

18. The display device of claim 11 , wherein a first width of the second pad is greater than a second width, and the first width of the second pad is closer to a first side surface at the first side of the circuit board than the second width.

19. The display device of claim 11 , wherein the first pad is an alignment pad, and the second pad is a signal pad.

20. The display device of claim 19 , further comprising an anisotropic conductive film electrically connecting the sensing pad and the second pad.
