DISPLAY PANEL WITH PRESSING SENSOR, AND ELECTRONIC DEVICE WITH PRESSING INPUT FUNCTION

摘要

An electronic device with pressing input function (1) includes a substantially rectangular parallelepiped-shaped housing (50). A display panel with pressure sensor (10) having a pressure sensor (20) and a display panel (30), a protective member (40), and an arithmetic circuit module (60) are disposed in the housing (50). In the display panel (30), a front polarizing plate (302) is disposed on a front face of a liquid crystal panel (301). The pressure sensor (20) includes piezoelectric films (201, 204) having birefringence, and electrodes (202, 203) are formed on both flat plate faces of the piezoelectric film (201) . The pressure sensor (20) is disposed between the liquid crystal panel (301) and the front polarizing plate (302). The piezoelectric films (201, 204) are arranged such that their uniaxial drawing directions (901, 904) are orthogonal to each other.
