Claim:
1. A display device equipped with a power generation function comprising: a first substrate including a movable electret first shutter with a first slit, a first electrode, and a second electrode on a side opposite to the first electrode with the first shutter between the first electrode and the second electrode; a second substrate including a second shutter with a second slit; a drive circuit connected to the first electrode to actuate the first shutter; a light source; and a rectifier circuit between the second electrode and the light source; wherein the first shutter is positively or negatively charged; the second electrode is connected to at least one of the drive circuit and the light source; electrostatic induction caused by movement of the first shutter generates an electromotive force on the second electrode; and the electromotive force is used to power the drive circuit and/or the light source.
