Abstract

According to one embodiment, a display device includes a first substrate including a display area and a terminal area, a second substrate opposed to the display area, a first sealing member formed between the first and second substrate and surrounding the display area, a second sealing member formed between the first sealing member and a first edge of the second substrate located at the terminal area side, and a first spacer formed between the first and second sealing member and formed at least in contact with the second sealing member. The first spacer includes a first side surface at the second sealing member side and a second side surface at the first sealing member side, and the first side surface at least partly projects toward the first edge.

Claims (28)

1. A display device comprising:

a first substrate including a display area in which switching elements are formed and a terminal area in which terminals are formed;

a second substrate opposed to the display area of the first substrate and unopposed to the terminal area of the first substrate;

a first sealing member formed between the first substrate and the second substrate and surrounding the display area;

a second sealing member formed between the first sealing member and a first edge of the second substrate located at the terminal area side; and

a first spacer formed between the first sealing member and the second sealing member and formed at least in contact with the second sealing member, wherein

the first spacer includes a first side surface at the second sealing member side and a second side surface at the first sealing member side,

the switching elements are covered by an insulating layer which is formed to partly overlap the second sealing member,

the first side surface projects toward the first edge in a region where the insulating layer is not formed, and

the first spacer has a first width in proximity to where the second sealing member overlaps the insulating layer and has a second width in proximity to where the second sealing member does not overlap the insulating layer and the second width is greater than the first width.

2. The display device of claim 1 , wherein the insulating layer is formed to overlap a circuit formed in the first substrate.

3. The display device of claim 2 , wherein the insulating layer is removed where the circuit is not formed.

4. The display device of claim 1 , wherein the width of the second sealing member varies between where the second sealing member does not overlap the insulating layer and where the second sealing member overlaps the insulating layer.

5. The display device of claim 1 , further comprising a second spacer formed between the second sealing member and the first edge, wherein

the first spacer is in contact with the insulating layer, and

the second spacer is not in contact with the insulating layer.

6. The display device of claim 1 , wherein the thickness of the insulating layer where the insulating layer overlaps the first sealing member or the second sealing member is less than the thickness of the insulating layer where the insulating layer overlaps the first spacer.

7. The display device of claim 1 , wherein

the first substrate comprises a first insulating substrate, wherein

the second sealing member is in contact with the insulating layer where the second sealing member overlaps the insulating layer, and

the second sealing member is in contact with the first insulating substrate where the second sealing member does not overlap the insulating layer.

8. The display device of claim 1 , wherein

the second substrate comprises a second edge opposite to the first edge, a third edge connecting the first edge and the second edge, and a fourth edge opposite to the third edge and connecting the first edge and the second edge, and

the first spacer extends along the first edge, and curves toward the direction of the second edge in a first corner between the first edge and the third edge and in a second corner between the first edge and the fourth edge.

9. The display device of claim 8 , wherein the second sealing member curves along the first spacer in the first corner and in the second corner.

10. The display device of claim 1 , wherein

the second sealing member has a third width corresponding to the first width and a fourth width corresponding to the second width, and

the sum of the first width and the third width is the same as the sum of the second width and the fourth width.
