Patent attributes
A touch panel which is thin, has a simple structure, or is easily incorporated into an electronic device is provided. The touch panel includes a first substrate, a second substrate, a first conductive layer, a second conductive layer, a third conductive layer, a fourth conductive layer, liquid crystal, and an FPC. The first conductive layer has a function of a pixel electrode. The second conductive layer has a function of a common electrode. The third and fourth conductive layers each have a function of an electrode of a touch sensor. The FPC is electrically connected to the fourth conductive layer. The first, second, third, and fourth conductive layers and the liquid crystal are provided between the first and second substrates. The first, second, and third conductive layers are provided over the first substrate. The FPC is provided over the first substrate.
