1. A display device comprising:
- an electro-optical layer;
a first driving electrode and a second driving electrode which drive the electro-optical layer;
a transistor which controls potential supply to the first driving electrode in a display region;
a scan line including a gate electrode of the transistor;
a scan line driving circuit which selects a potential to be supplied to the scan line;
a driver integrated circuit which is connected to the scan line driving circuit via a first terminal in a first region and which supplies a control signal to the scan line driving signal;
a switch circuit which is arranged outside the driver integrated circuit and which selects a potential to be supplied to the second driving electrode;
a detection circuit which detects that an object is close or in contact;
a plurality of source wires connected to the switch circuit and the detection circuit;
an inspection wire connected to the scan line driving circuit;
a second terminal connected to the inspection wire; and
a protection circuit arranged between the inspection wire and the second terminal,wherein, when it is assumed that an extending direction of the switch circuit is a first direction, that one side in the first direction is a first side, and that the other side therein is a second side, andthe plurality of source wires are closer to the first side than a center of the first region in the first direction, and the second terminal and the protection circuit are closer to the second side than the center of the first region in the first direction.

Abstract
The display device includes: a scan line driving circuit selecting a potential supplied to a scan line; a driver chip; a plurality of source wires connected to a detection circuit; a terminal connected to an inspection wire controlling the scan line driving circuit; and a protection circuit arranged between the inspection wire and the terminal When it is assumed that an extending direction of a switch circuit connected with the plurality of source wires is an X axis direction, that one side of the X axis direction is an X1 side, and that the other side therein is an X2 side, the plurality of source wires are arranged closer to the X1 side than a center of the region in the X axis direction, and the terminal and the protection circuit are arranged closer to the X2 side than the center of the region in the X axis direction.
