Abstract: A power storage device that can be discharged safely and easily is provided. The power storage device includes a secondary battery covered with an exterior body, a radiator plate in contact with a surface of the exterior body, and a projection. The projection has conductivity and is held over the exterior body in the normal condition. When the projection penetrates the exterior body to be inserted into the secondary battery, the secondary battery can be short-circuited and discharged. Heat can be efficiently released from the projection to the radiator plate. Thus, the secondary battery can be discharged safely at high speed without thermal runaway.

Abstract: An electronic device that can easily increase the viewing angle and has a reduced screen-door effect is provided. In the electronic device, images displayed on a display panel with a low pixel density and a display panel with a high pixel density are synthesized to be seen. The electronic device includes a first display panel that has a relatively large screen size and a low pixel density, and a second display panel and a third display panel each of which has a relatively small screen size and a high pixel density. The electronic device is configured such that visual information enters the central field of view from the second display panel or the third display panel and visual information enters the peripheral field of view from the first display panel. Such a configuration can easily increase the viewing angle and reduce the screen-door effect.

Abstract: An optical device with less influence of stray light is provided. The optical device is thin and includes a half mirror, a first lens, a retardation plate, a reflective polarizing plate, and a second lens. In the optical device, a geometric phase lens which has negative and positive refractive power is used as the first lens, whereby images can be focused after magnified optically. Thus, the optical device can have a wide viewing angle. In the case where stray light occurs due to birefringence of an optical material, negative refractive power of the first lens can prevent the stray light from being focused on the eye direction. Accordingly, image degradation recognized due to stray light can be prevented.
