Abstract

A display panel is provided. The display panel includes a first substrate, a blocking structure, and a seal layer. The first substrate has a display region. The blocking structure is disposed on the first substrate and located outside the display region, wherein the blocking structure includes a plurality of first blocking walls, and a distance between two adjacent first blocking walls is 7-50 μm. The seal layer is disposed on the first substrate and surrounds the first blocking walls, wherein each of the first blocking walls has a top surface, and the seal layer is in direct contact with at least one of the top surfaces.

First claim

What is claimed is:

1 . A display panel, comprising:
a first substrate having a display region; a blocking structure disposed on the first substrate and located outside the display region, wherein the blocking structure comprises a plurality of first blocking walls, and a distance between two of the adjacent first blocking walls is 7-50 μm; and a seal layer disposed on the first substrate and surrounding the first blocking walls, wherein each of the first blocking walls has a top surface, and the seal layer is in direct contact with at least one of the top surfaces.

2 . The display panel according to claim 1 , wherein each of the first blocking walls has a width of 7-100 μm.

3 . The display panel according to claim 1 , wherein the blocking structure further comprises a plurality of second blocking walls surrounding the seal layer.

4 . The display panel according to claim 3 , wherein a distance between any two of the adjacent second blocking walls is 7-50 μm, and each of the second blocking walls has a width of 7-100 μm.

5 . The display panel according to claim 1 , further comprising:
a second substrate; and a plurality of spacers disposed between the first substrate and the second substrate and contacting the first substrate and the second substrate, wherein the spacers are located in the display region; wherein each of the spacers has a first height, the blocking structure has a second height, the first height is greater than the second height, and the difference between the first height and the second height is 1-2 μm.

6 . The display panel according to claim 1 , wherein the seal layer covers at least one of the first blocking walls.

7 . The display panel according to claim 1 , wherein an inner edge of the seal layer and an outer edge of the display region are separated, and a distance between the inner edge of the seal layer and the outer edge of the display region is 100-200 μm.

8 . The display panel according to claim 1 , wherein the first substrate has a metal wire region, the metal wire region having a metal wire densely arranged region and a metal wire dispersedly arranged region, and each of the first blocking walls has a bending region disposed corresponding to the metal wire dispersedly arranged region of the metal wire region.

9 . The display panel according to claim 1 , wherein the blocking structure has a squared shape or a ring shape, and the blocking structure has at least a corner region being a right angle or an arc with a radius of curvature of 0-1000 μm.

10 . The display panel according to claim 1 , wherein the first substrate has a non-transparent region, and the blocking structure has at least a part having a shape being conformal with a part of the outline of the non-transparent region.
