发明名称 DISPLAY APPARATUS AND ELECTRONIC DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a display apparatus and an electronic device for enabling an analog display by an indication section movable on a display surface and a display in a display panel. SOLUTION: The display apparatus 100 is provided with the display panel 10 having the display surface 10a, an indicator 30 as the indication section, a rotor 31 composed of a permanent magnet as a magnetic field generation section provided in the indicator 30, and induction coils L as a plurality of induced magnetic field generation sections provided on the non-display surface side opposite to the display surface 10a in the predetermined direction. In the indicator 30, the rotor 31 is disposed so as to face at least one of a plurality of the induction coils L through the display panel 10. An interval between the rotor 31 and the induction coil L through the display panel 10 is a distance at which the indicator 30 is movable in the predetermined direction since the induced magnetic fields generated from the rotor 31 and the induction coil L are mutually repelled or sucked.
