Display device with touch sensor including structure for securing stability of eectrical connection between external lines and the touch sensor

A display device comprising:

• a substrate, the substrate having a display region including a plurality of pixels;
• a multilayer insulator covering the plurality of pixels;
• a plurality of detection electrodes arranged so as to overlap the display region;
• a terminal on the substrate, the terminal located along an edge of the substrate;
• a first detection line electrically connected to the terminal;
• and
• a second detection line electrically connected to one of the plurality of detection electrodes,
• the multilayer insulator comprises:
• a first inorganic insulating layer;
• a second inorganic insulating layer;
• and
• an organic insulating layer between the first inorganic insulating layer and the second inorganic insulating layer, wherein
• an edge of the organic insulating layer is located between the display region and an edge of the first inorganic insulating layer in a planar view,
• the edge of the first inorganic insulating layer is located between the edge of the organic insulating layer and the edge of the substrate in the planar view,
• the second inorganic insulating layer is in contact with the first inorganic insulating layer outside the edge of the organic insulating layer,
• the first detection line and the second detection line are electrically connected with each other at a contact portion,
• the contact portion is located between an edge of the organic insulating layer and the edge of the second inorganic insulating layer in the planar view, and
• the first detection line intersects the edge of the first inorganic insulating layer.
