Display device

A display device comprising:

• an electro-optical layer;
• a plurality of driving electrodes arranged in a first direction;
• a driver chip outputting a video signal;
• a switch circuit formed outside of the driver chip and including a plurality of first switch elements and a plurality of second switch elements;
• a plurality of control signal line connecting to the switch circuit;
• and
• a detection circuit detecting a touch or an approach of an object,
• wherein each of the plurality of first switch elements and each of the plurality of second switch elements is controlled by a signal supplied by the plurality of control signal lines respectively,
• the detection circuit is electrically connected to the plurality of driving electrodes by the plurality of first switch elements respectively,
• each of the plurality of second switch elements supplies a pulse signal to the plurality of driving electrodes respectively,
