Abstract

A display device, including a display region formed of a plurality of pixels and a frame region formed on an outer side of the display region, includes a sealing film configured to cover the display region, a blocking portion formed in the frame region surrounding the display region, and buffering portions formed at least at two positions so as to be separated from each other on at least one straight line path extending from the display region to reach the blocking portion. In one embodiment of the present invention, the buffering portions have a wave shape in plan view.

Claims (20)

1. A display device, including a display region formed of a plurality of pixels and a frame region formed on an outer side of the display region, comprising:

a sealing film configured to cover the display region;

a blocking portion formed in the frame region surrounding the display region; and

buffering portions formed at least at two positions so as to be separated from each other on at least one straight line path extending from the display region to reach the blocking portion.

2. The display device according to claim 1 , wherein the buffering portions have a wave shape in plan view.

3. The display device according to claim 1 , wherein the buffering portions are arranged at a predetermined interval in plan view.

4. The display device according to claim 1 , wherein the buffering portions have a gap at a corner of the frame region.

5. The display device according to claim 1 , wherein the buffering portions are formed lower than the blocking portion in sectional view.

6. The display device according to claim 1 , wherein the buffering portions formed at the two positions so as to be separated from each other are formed so as to be higher on an inner side in sectional view.

7. A display device, including a display region formed of a plurality of pixels and a frame region formed on an outer side of the display region, comprising:

a pixel comprising a pixel circuit and a light emitting element corresponding to the pixel circuit;

a sealing film configured to cover the display region and the frame region;

a substrate having the pixel formed thereon;

a blocking portion formed in the frame region so as to upwardly protrude; and

two buffering portions formed between the display region and the blocking portion so as to be separated from each other and to protrude toward the sealing film side.

8. The display device according to claim 7 , wherein the blocking portion is formed of a resin layer formed between the light emitting element and a circuit layer in which the pixel circuit is formed.

9. The display device according to claim 7 ,

wherein the sealing film comprises a lower layer barrier film, an upper layer barrier film, and a sealing planarizing film formed between the lower layer barrier film and the upper layer barrier film, and

wherein the sealing planarizing film is thinner in the frame region than in the display region.

10. The display device according to claim 9 , wherein the sealing film has a thickness that is gradually decreased toward an end of the substrate.
