Abstract

A display panel is provided, which includes a sealant connected between two opposite substrates. A first curved segment of the sealant includes two first sealant nodes. A second curved segment of the sealant includes two second sealant nodes. The radius of the first curved segment is greater than that of the second curved segment. In addition, the distance between the two first sealant nodes is greater than the distance between the two second sealant nodes.

wherein the two sealant nodes are spaced apart by a first distance (D), and an edge of the display area is spaced apart from an edge of the first substrate by a second distance (d), and the curved segment has a rotation radius (r),
wherein the first distance (D), the second distance (d) and the rotation radius (r) satisfy the following equation:
0< D ≦2√{square root over ( d (2 r−d ))}.

2. The display panel as claimed in claim 1 , wherein the sealant further comprises a straight segment connecting to the curved segment.

3. The display panel as claimed in claim 2 , wherein a width of one of the two sealant nodes is greater than a width of the straight segment.

4. The display panel as claimed in claim 2 , wherein the curved segment further comprises a connection portion connecting to the two sealant nodes, wherein a width of one of the two sealant nodes is greater than a width of the connection portion, and the width of the connection portion is less than or equal to the width of the straight segment.

5. The display panel as claimed in claim 2 , wherein the curved segment further comprises an overlapping portion connecting to the two sealant nodes, wherein a width of one of the two sealant nodes is greater than a width of the overlapping portion, and the width of the overlapping portion is greater than the width of the straight segment.

6. The display panel as claimed in claim 1 , wherein an outer edge of one of the two sealant nodes comprises a first end point, a second end point, and a third end point, wherein the first and the second end points are separated by a predetermined distance, and the second and the third end points are separated by the predetermined distance;
wherein an inner edge of one of the two sealant nodes comprises a fourth end point, a fifth end point, and a sixth end point, wherein the fourth and the fifth end points are separated by the predetermined distance, and the fifth and the sixth end points are separated by the predetermined distance;
wherein an area enclosed by the first point, the second point, and the third point is greater than an area enclosed by the fourth point, the fifth point, and the sixth point.

7. display panel, comprising:
a first substrate;
a second substrate, arranged opposite to the first substrate;
a display layer, positioned between the first substrate and the second substrate; and
a sealant, positioned between the first substrate and the second substrate and neighboring the display layer, and the sealant comprising a curved segment, wherein the curved segment comprises two sealant nodes;
wherein the two sealant nodes are spaced apart by a first distance (D), and the curved segment has a rotation radius (r),
wherein the first distance (D) and the rotation radius (r) satisfy the following equation:
0< D ≦2√{square root over (200(2 r− 200))}

2√{square root over (10(2 r− 10))}≦ D≦ 2√{square root over (200(2 r− 200))}

wherein r and D in unit of micrometer.

9. The display panel as claimed in claim 7 , wherein the sealant further comprises a straight segment connecting to the curved segment.

10. The display panel as claimed in claim 9 , wherein a width of one of the two sealant nodes is greater than a width of the straight segment.

11. The display panel as claimed in claim 9 , wherein the curved segment further comprises a connection portion connecting to the two sealant nodes, wherein a width of one of the two sealant nodes is greater than a width of the connection portion, and the width of the connection portion is less than or equal to the width of the straight segment.

12. The display panel as claimed in claim 9 , wherein the curved segment further comprises an overlapping portion connecting to the two sealant nodes, wherein a width of one of the two sealant nodes is greater than a width of the overlapping portion, and the width of the overlapping portion is greater than the width of the straight segment.

13. The display panel as claimed in claim 7 , wherein an outer edge of one of the two sealant nodes comprises a first end point, a second end point, and a third end point, wherein the first and the second end points are separated by a predetermined distance, and the second and the third end points are separated by the predetermined distance;
