## Abstract

A frame sealing glue includes a frame sealing glue body having an inner layer portion (211) and an outer layer portion (212). The frame sealing glue further includes an intermediate film layer (22) disposed between the inner layer portion (211) and the outer layer portion (212), and a plurality of enclosed spaces (P) are formed by the intermediate film layer (22) and the inner layer portion (211) or the outer layer portion (212) of the frame sealing glue body. A display panel and a display device are also provided. By means of the frame sealing glue, the display panel and the display device according to the embodiments of the present disclosure, it avoids a leakage phenomenon when the frame sealing glue is broken at different points, thereby increasing ability of the frame sealing glue for resisting external atmospheric pressure.

## Claims

### Claim 1

A frame sealing glue, comprising:
a frame sealing glue body having an inner layer portion and an outer layer portion; and
an intermediate film layer disposed between the inner layer portion and the outer layer portion;
wherein a plurality of enclosed spaces are formed by the intermediate film layer and the inner layer portion or the outer layer portion of the frame sealing glue body,
wherein the intermediate film layer comprises a wave-shaped curved line having a plurality of semicircular curved line portions, the wave-shaped curved line forming a discontinuous curved line such that the intermediate film layer is disconnected at a corner of an enclosed frame formed by the frame sealing glue,
wherein a peak and a valley of the wave-shaped curved line intersect with the inner layer portion and the outer layer portion of the frame sealing glue body, respectively, or with the outer layer portion and the inner layer portion of the frame sealing glue body, respectively,
wherein each of the inner layer portion and the outer layer portion is a continuous closed line, and
wherein the intermediate film layer is made of different material from the frame sealing glue body.

### Claim 2 (depends on 1)

The frame sealing glue according to claim 1, wherein the frame sealing glue body is formed from an ultraviolet-curable glue.

### Claim 3 (depends on 1)

The frame sealing glue according to claim 1, wherein a thickness of the intermediate film layer is equal to a thickness of the inner layer portion or the outer layer portion of the frame sealing glue body.

### Claim 4 (depends on 1)

A display panel, comprising a first substrate and a second substrate opposite to the first substrate, wherein the display panel further comprises the frame sealing glue according to claim 1, and the frame sealing glue is disposed between the first substrate and the second substrate.

### Claim 5 (depends on 4)

The display panel according to claim 4, wherein an organic light emitting diode is provided in a region enclosed by the frame sealing glue on the first substrate or the second substrate.

### Claim 6 (depends on 4)

A display device, comprising the display panel according to claim 4.
