Abstract
To increase the detection sensitivity of a touch panel, provide a thin touch panel, provide a foldable touch panel, or provide a lightweight touch panel. A display element and a capacitor forming a touch sensor are provided between a pair of substrates. Preferably, a pair of conductive layers forming the capacitor each have an opening. The opening and the display element are provided to overlap each other. A light-blocking layer is provided between a substrate on the display surface side and the pair of conductive layers forming the capacitor.
