Abstract

The present invention provides a display device and a television device with which it is possible to reduce the thickness of the device profile while also realizing desirable acoustic characteristics. This display device includes: a first plate-shaped object; a display module including a display element and a second plate-shaped object that supports the display element, the display module being disposed so as to face the first plate-shaped object; a liquid layer formed by sealing up a liquid between the first plate-like object and the display module; and a vibrator provided to the first plate-shaped object and/or the display module. The loss coefficient of the display device at 25° C. is 1×10 −2 or greater and a thickness ratio between the first plate-shaped object and the display module is from 1:10 to 10:1.

Claims (14)

1. A display device comprising

a first plate-shaped object,

a display module comprising a display element and a second plate-shaped object that supports the display element, the display module being disposed so as to face the first plate-shaped object,

a liquid layer formed by sealing up a liquid between the first plate-shaped object and the display module, and

a vibrator provided to the first plate-shaped object and/or the display module,

wherein the display device has a loss coefficient at 25° C. of 1×10 −2 or higher,

a thickness ratio between the first plate-shaped object and the display module is from 1:10 to 10:1.

2. The display device according to claim 1 , wherein at least one of the first plate-shaped object and the second plate-shaped object is composed of a glass sheet.

3. The display device according to claim 1 , wherein the display element is an OLED.

4. The display device according to claim 1 , comprising a first resin layer that is disposed on at least one surface of the display module.

5. The display device according to claim 1 , comprising a second resin layer that is disposed on at least one surface of the first plate-shaped object.

6. The display device according to claim 1 , comprising at least one resin layer that covers a side surface of the first plate-shaped object.

7. The display device according to claim 1 , wherein a mass ratio between the first plate-shaped object and the display module is from 1:10 to 10:1.

8. A television device comprising the display device according to claim 1 .
