Abstract
To provide a display device with a touch detection function capable of suppressing an increase of price.The display device includes a pixel array that has a plurality of pixels disposed in a matrix form, a plurality of scan lines that are disposed in each row of the pixel array and supply a scan signal to the plurality of pixels disposed in each corresponding row, a plurality of signal lines that are disposed in each column of the pixel array and supply an image signal to the plurality of pixels disposed in each corresponding column, and a plurality of drive electrodes that are disposed in the pixel array and supply a drive signal to the plurality of pixels at a time of displaying an image. A coil that generates a magnetic field is formed using the plurality of drive electrodes at a time of detecting an external proximity object.
