PROBLEM TO BE SOLVED: To make a display apparatus small-sized, light-weight, and thin by integrating a display device like a liquid crystal cell and a thin secondary battery into a module structure. SOLUTION: A display apparatus 10 is provided with a display device 11 like a liquid crystal cell, and a thin secondary battery 12 is arranged on the rear side of the display device 11. A heat insulating layer having <=5 W/m.K, preferably, <=1 W/m.K heat conductivity is formed between the display device 11 and the secondary battery 12 by a heat insulating plate 13, and they are integrated to constitute the display device 11 and the secondary battery 12 into a module structure. |
