Abstract
The electronic device includes a first housing including a solar battery, a first display device, and a first structure body and a second housing including a second display device, a coil, an electric double-layer capacitor, a signal processing circuit, a charge and discharge control circuit, and a second structure body. The electronic device can be folded so that display surfaces of the first housing and the second housing face each other and the first structure body and the second structure body face each other. The solar battery is provided on a surface of the first housing on the rear side of the first display device. A pixel included in the first display device and a pixel included in the second display device each include a liquid crystal element, a first pixel circuit, a light-emitting element, and a second pixel circuit. The liquid crystal element includes a reflective electrode having an opening and can perform display by reflecting external light. The light-emitting element can perform display by emitting light toward the display surface through the opening.
