Abstract

A display apparatus capable of reducing the lowering of detection sensitivity is provided. A display apparatus provided with a pixel array having a plurality of pixels arranged in a matrix form includes: detection electrodes which are in parallel with each other, which are arranged so as to extend in a first direction, and which are connected so as to forma magnetic-field detection coil; and a detection electrode having one end which is arranged inside the magnetic-field detection coil and which is connected to the magnetic-field detection coil, and the other end which is electrically insulated from the magnetic-field detection coil. At the time of each of the magnetic field detection and the electric field detection, an external object is detected based on a change in a signal in the detection electrodes.
