Abstract

A display device includes: a first substrate having a first area; a second substrate having a second area larger than the first area and positioned above the first substrate; interconnects on the first substrate; connection pads on a side surface of the first substrate and electrically connected to the interconnects; and a first cover member on the side surface of the first substrate, wherein a side surface of the second substrate protrudes from the side surface of the first substrate in a first direction, and the first cover member is located under the second substrate.

Claims (41)

1. A display device comprising:

a first substrate having a first area;

a second substrate having a second area larger than the first area and positioned above the first substrate;

interconnects on the first substrate;

connection pads on a side surface of the first substrate and electrically connected to the interconnects; and

a first cover member on the side surface of the first substrate,

wherein a side surface of the second substrate protrudes from the side surface of the first substrate in a first direction, and the first cover member is located under the second substrate.

2. The display device of claim 1 , wherein the first cover member comprises: a first portion extending in a second direction intersecting with the first direction; and a second portion extending in the first direction from an upper end of the first cover member, wherein the second portion is fixed to the second substrate.

3. The display device of claim 1 , wherein the first cover member comprises: a first portion extending in a second direction intersecting with the first direction; and a second portion extending in an opposite direction to the first direction from an upper end of the first cover member, wherein the second portion is fixed to the second substrate.

4. The display device of claim 1 , wherein the second substrate comprises:

a first region overlapping the first substrate in a second direction intersecting with the first direction; and

a second region not overlapping the first substrate in the second direction, and wherein an accommodating groove is in the second region so that an upper end of the first cover member is inserted into the accommodating groove.

5. The display device of claim 1 , wherein the first cover member comprises:

a first vertical portion extending in a second direction intersecting with the first direction;

a first protruding portion protruding in the first direction; and

a first depressed portion protruding in an opposite direction to the first direction, wherein an end of the first vertical portion is fixed to the second substrate.

6. The display device of claim 5 , further comprising:

a second cover member on another side surface of the first substrate and under the second substrate, wherein the second cover member comprises a second vertical portion extending in a second direction intersecting with the first direction, a second protruding portion protruding in an opposite direction to the first direction, and a second depressed portion protruding in the first direction, and wherein an end of the first vertical portion is fixed to the second substrate.

7. The display device of claim 6 , wherein the first protruding portion is aligned with the second depressed portion in the first direction, and the first depressed portion is aligned with the second protruding portion in the first direction.

8. The display device of claim 1 , further comprising:

a bottom cover positioned under the first substrate and comprising a bottom, a first sidewall and a second sidewall, wherein an upper end of the first cover member is fixed to a lower surface of the second substrate, and a lower end of the first cover member is fixed to the first sidewall.

9. The display device of claim 8 , further comprising:

a second cover member on another side surface of the first substrate and under the second substrate, wherein an upper end of the second cover member is fixed to the lower surface of the second substrate and a lower end of the second cover member is fixed to the second sidewall, and wherein a length of the first sidewall is different from a length of the second sidewall in a second direction intersecting with the first direction.

10. The display device of claim 1 , wherein the first substrate is a color filter substrate, and the second substrate is a TFT substrate, and wherein the display device further comprises:

a first spacer between the first substrate and the second substrate, and a second spacer between the first spacer and the first substrate.

11. The display device of claim 10 , wherein a side surface of the first spacer is aligned with the side surface of the second substrate, and a side surface of the second spacer is aligned with the side surface of the first substrate.

12. The display device of claim 11 , wherein the first spacer comprises a blue colorant.

13. The display device of claim 1 , wherein the side surface of the second substrate protrudes from the side surface of the first substrate by a distance of 0.3 mm to 0.5 mm.

14. A display device comprising:

a display panel comprising a first substrate and a second substrate, each of the first substrate and the second substrate having first to fourth side surfaces; and

first to fourth cover members on the first to fourth side surfaces, respectively,

wherein the display panel comprises

interconnects on the first substrate, and

connection pads on the first side surface of the first substrate and electrically connected to the interconnects,

wherein the first side surface of the second substrate protrudes from the first side surface of the first substrate, and the first cover member is on the first side surface and under the second substrate and is spaced apart from the connection pads.

15. The display device of claim 14 , wherein the second to fourth side surfaces of each of the first substrate and the second substrate are aligned with one another in a second direction intersecting with the first direction, wherein the second cover member is on the second side surface of each of the first substrate and the second substrate, wherein the third cover member is on the third side surface of each of the first substrate and the second substrate, and wherein the fourth cover member is on the fourth side surface of each of the first substrate and the second substrate.

16. The display device of claim 14 , wherein the second side surface of the second substrate opposed to the first side surface of the second substrate protrudes from the first side surface of the first substrate in an opposite direction to the first direction, and wherein the second cover member is on the second side surface of the first substrate and under the second substrate.

17. The display device of claim 16 , wherein the third side surface of the second substrate connecting the first side surface with the second side surface of the second substrate protrudes from the third side surface of the first substrate in a second direction intersecting with the first direction, and wherein the third cover member is on the third side surface of the first substrate and under the second substrate.

18. The display device of claim 17 , wherein the fourth side surface of the second substrate opposed to the third side surface of the second substrate protrudes from the fourth side surface of the first substrate in an opposite direction to the second direction, and wherein the fourth cover member is on the fourth side surface of the first substrate and under the second substrate.

19. The display device of claim 14 , wherein a side surface of the first cover member is aligned with the first side surface of the second substrate.

20. The display device of claim 14 , wherein at least one of the first cover member, the second cover member, the third cover member and the fourth cover member overlaps the second substrate in a second direction intersecting the first direction.
