Abstract
An electronic device with pressing input function has a substantially rectangular parallelepiped-shaped housing. A display panel with pressure sensor and an arithmetic circuit module are disposed in the housing. The display panel with pressure sensor is composed of a pressure sensor and a display panel. In the display panel, a front polarizing plate is disposed on a front face of a liquid crystal panel. In the pressure sensor, electrodes are formed on both respective flat plate faces of a piezoelectric film having birefringence. The pressure sensor is disposed between the liquid crystal panel and the front polarizing plate of the display panel, and a uniaxial drawing direction of the piezoelectric film is parallel to a polarizing direction of the front polarizing plate.
