(57) [Problem] To provide a module structure by integrating a display device such as a liquid crystal cell and a thin secondary battery into a module structure, thereby reducing the size, weight and thickness of the display device. A display device includes a display device such as a liquid crystal cell, and a thin secondary battery is disposed on a back side of the display device. A heat shielding layer having a thermal conductivity of 5 W / m · K or less, preferably 1 W / m · K or less is formed between the display device 11 and the secondary battery 12 by a heat shielding plate 13 and integrated therewith. And a secondary battery 12 in a module structure. |
