Abstract

A frame sealant composition, a display panel and a display device are provided, and the frame sealant composition includes a frame sealant ( 1 ) and an elastomer ( 2 ), wherein upon the frame sealant composition being used for cell-assembling of two substrates ( 100, 200 ), the elastomer ( 2 ) is pressed by the two substrates ( 100, 200 ) to form a barrier structure. With the frame sealant composition provided by the embodiment of the present disclosure, an impact of the liquid crystal layer ( 400 ) to the frame sealant in the process of cell-assembling the two substrates is effectively reduced, and a puncture resistance of the frame sealant is improved, thereby a product yield is increased.

First claim

The invention claimed is:

1. A display panel, comprising:
a first substrate, a second substrate, a liquid crystal layer and a sealing layer for sealing the liquid crystal layer between the first substrate and the second substrate,
wherein the sealing layer comprises a first sealing pattern made of a frame sealant composition, the frame sealant composition comprises a frame sealant and elastomer, wherein the frame sealant composition is used for cell-assembling the first substrate and the second substrate, and each of the elastomers is pressed by the two substrates to form a barrier structure;
wherein each of the elastomers upon being not pressed is of a ball shape, and the diameter of the elastomer upon being not pressed is larger than a distance between the first substrate and the second substrate;
the first sealing pattern comprises a plurality of mutually nested annular sealing areas surrounding the liquid crystal layer;
wherein in any two adjacent annular sealing areas, a number of the elastomers in a unit volume of an annular sealing area closer to the liquid crystal layer is greater than a number of the elastomers in a unit volume of an annular sealing area further away from the liquid crystal layer.

2. The display panel according to claim 1 , wherein the sealing layer further comprises a second sealing pattern comprising the frame sealant composition, and the second sealing pattern is disposed at a side of the first sealing pattern away from the liquid crystal layer.

3. A display device, comprising the display panel according to claim 1 .

4. The display panel according to claim 1 , wherein a material of the elastomers comprises at least one of olefin hydrocarbon and organic silicon.

5. The display panel according to claim 1 , wherein a mass percentage of the elastomers in the frame sealant composition is from 0.01% to 80%.

6. The display panel according to claim 5 , wherein a mass percentage of the elastomers in the frame sealant composition is from 10% to 70%.

7. The display panel according to claim 5 , wherein a mass percentage of the elastomers in the frame sealant composition is from 30% to 50%.

8. The display panel according to claim 1 , wherein the elastomers are evenly distributed in the frame sealant.

9. The display panel according to claim 1 , wherein the elastomer upon being not pressed is of a ball shape, and a diameter of the elastomer upon being not pressed is from 3.6 μm to 11 μm.
