Abstract: An electronic device having a novel structure, specifically, an electronic device having a novel structure that can be changed into various appearances is provided. Specifically, after an active material layer is formed on one or both surfaces of a current collector, the active material layer in a bent region is partly removed. The removed region of the active material layer can be in a linear shape, a dot shape, or a matrix shape, for example. After the active material layer is formed on one or both surfaces of the current collector, laser processing for removing part of the active material layer in an irradiation region is performed using laser light or the like. On the region where the surface of the current collector is exposed, the active material layer is not provided, and this region is a region that does not function as a battery. Owing to this region, a secondary battery with a wide movable region can be achieved.

Abstract: In order to display 3D images by a parallax barrier method, a display screen and the eyes of a viewer need to have a specific positional relation. An object is to provide a display device with an extended area where the viewer can perceive 3D images with the naked eye. Attention is focused on the position of the viewer with respect to pixels provided in a display device and a mode of a parallax barrier provided between the viewer and the pixels. This leads to a structure in which the position of the viewer with respect to pixels is specified by using an ultrasonic wave to change a mode of a parallax barrier in accordance with the position of the viewer, thereby achieving the above object.
