Abstract

To provide a display device with high reliability, which is capable of supporting a display panel well even when the display panel is enlarged, and capable of radiating the heat generated in the display panel well. A display device 100 of the present invention has an organic EL panel (display panel) 150 and a reinforcing structure 160 provided on the backside of the display panel 150. The reinforcing structure 160 comprises a base plate 161 forming a part adhered to a back face of the organic EL panel 150, and a heat radiation member 170 provided on the base plate 161.

Claims

1. A display panel,

wherein the reinforcing structure comprises a supporting substrate forming a part adhered to a back face of the display panel, and a heat radiation device having a display panel and a reinforcing structure provided on the backside of the display member provided on the supporting substrate,

wherein the heat radiation member comprises a plurality of plate members arranged on the supporting substrate to intersect each other a such that the plate members are formed substantially in parallel crosses in plan view, and

wherein the plurality of plate members are more densely arranged on the supporting substrate corresponding to a peripheral portion of the display panel.

2. The display device according to claim 1,

wherein each of the plate members is provided with at least one heat radiation hole formed by cutting out part thereof.

3. The display device according to claim 2,

wherein the at least one heat radiation hole is formed by cutting out the end of the plate member opposite to the supporting substrate.

4. The display device according to claim 1,

wherein each of the plate members is provided with at least one heat radiation hole passing though a lateral face of the plate member.

5. The display device according to claim 2,

wherein a plurality of the heat radiation holes are provided to permit communication between a plurality of regions on the supporting substrate defined by the plurality of plate members.

6. The display device according to claim 5,

wherein the plurality of the heat radiation holes are provided to permit communication, in the vertical direction of the panel, between a plurality of regions on the supporting substrate defined by the plurality of plate members.

7. The display device according to claim 5,

wherein the plurality of the heat radiation holes are provided to permit communication, in the horizontal direction of the panel, between a plurality of regions on the supporting substrate defined by the plurality of plate members.

8. The display device according to claim 6,

wherein the plurality of the heat radiation holes that permit communication between the regions defined by the plurality of plate members are provided substantially at coaxial positions in side view in the corresponding communicating direction.

9. The display device according to claim 1,

wherein heat radiation fins are provided on the supporting substrate.

10. The display device according to claim 9,

wherein the heat radiation fins extend substantially parallel to a direction in which the plurality of the heat radiation holes are continuously provided, which permits communication between the regions on the supporting substrate defined by the plurality of plate members.

11. The display device according to claim 1,

wherein the heat radiation member is made of metal.

12. The display device according to claim 1,

wherein the display panel is a display panel comprising organic electroluminescent elements.

13. The display device according to claim 12,

wherein the supporting substrate also serves as a sealing structure for the organic electroluminescent elements.

14. The display device according to claim 2, further comprising a chassis accommodating the display panel and the heat radiation member,

wherein the chassis includes air supply means and air exhaust means arranged in close proximity to the heat radiation member, and

the air supply means and the air exhaust means are arranged along the direction in which the heat radiation holes are continuously provided.

15. An electronic apparatus comprising the display device according to claim 1.
