Touch detection device, and display device including the same

A display device comprising:

• a light emitting layer disposed on a substrate and emitting light;
• and
• a touch detecting portion disposed on the light emitting layer and detecting a touch input, wherein
• the touch detecting portion includes:
• a touch area including a plurality of driving electrodes and a plurality of detecting electrodes intersecting the plurality of driving electrodes, and comprising:
• a first area that is flat;
• and
• a second area that extends from the first area in a first direction and is flat or bent based on a movement of a first roller member;
• a first pad portion disposed adjacent to an edge of the touch area and including:
• a first driving pad portion electrically connected to a plurality of first driving electrodes disposed in the first area through a plurality of first driving lines;
• and
• a first detecting pad portion electrically connected to a plurality of first detecting electrodes disposed in the first area through a plurality of detecting lines;
• and
• a second pad portion disposed adjacent to the edge of the touch area and including a second driving pad portion electrically connected to a plurality of second driving electrodes disposed in the second area through a plurality of second driving lines,
• each of the plurality of second driving lines includes:
• a first line section connected to one of the plurality of second driving electrodes and extending in the first direction;
• and
• a second line section bent from an end of the first line section to a second direction perpendicular to the first direction and connected to the second driving pad portion, and
• the first line section includes a first sub-section including a columnar conductor and a second sub-section that does not include the columnar conductor.
