Abstract
To provide a touch panel with reduced disturbance of display and with improved mechanical strength by suppressing variation in the space between a pair of substrates which form the touch panel even when in contact with an object to be detected. A pixel portion including a plurality of pixels is provided between a pair of substrates. Each pixel includes a photosensor portion which detects that the object to be detected is in contact with one of the pair of substrates, and a MEMS portion which generates a mechanical displacement in a direction perpendicular to the pair of substrates when a signal based on a detection result of the photosensor portion is input.
