Abstract

A first transparent electrode film, which is a component of a SW-LCD for viewing angle control, is used as a touch panel. When a contacting object contacts the surface of the first transparent electrode film, a position detector detects currents flowing from plural parts of the first transparent electrode film so as to detect the contacting position of the contacting object, with reference to the detection result. With this, it is possible to provide a built-in touch sensor display device which is thin, lightweight, and low-cost, a viewing angle control device, and an electronic device.
