Touch sensor and display device

A touch sensor comprising:

• a base layer comprising a sensing area and a peripheral area around the sensing area, the sensing area comprising a first area and a second area located on an outer side of the first area in a first direction;
• first electrode units comprising a plurality of first touch electrodes arranged on the base layer in the first direction and electrically connected to one another in the first direction, wherein the first electrode units are arranged in a second direction intersecting the first direction and spaced apart from one another in the second direction, and are located in the first area;
• second electrode units comprising a plurality of second touch electrodes arranged on the base layer in the second direction and electrically connected to one another in the second direction, wherein the second electrode units are arranged in the first direction and spaced apart from one another in the first direction, and are located in the first area;
• and
• a first conductive pattern disposed on the base layer in the second area, wherein the first conductive pattern is connected to one of the second electrode units that is adjacent thereto in the first direction.

A display device comprising:

• a base substrate comprising a display area;
• a self-luminous element disposed on the base substrate in the display area;
• an thin-film encapsulation layer disposed on the self-luminous element and comprising a sensing area overlapping with the display area, the sensing area comprising a first area and a second area located on the outer side of the first area in the first direction;
• first electrode units comprising first touch electrodes arranged on the thin-film encapsulation layer in the first direction and electrically connected to one another in the first direction, the first electrode units being arranged in a second direction intersecting the first direction in the first area and spaced apart from one another in the second direction;
• second electrode units comprising second touch electrodes arranged on the thin-film encapsulation layer in the second direction and electrically connected to one another in the second direction, the second electrode units being arranged in the first direction in the first area and spaced apart from one another in the first direction;
• and
• a first electrode pattern located on the thin-film encapsulation layer and comprising a first portion electrically connected to one of the first electrode units that is adjacent thereto in the first direction, and a second portion extended from the first portion to the second area,
• wherein a width of the first electrode pattern in the first direction is less than a width of the first touch electrodes in the first direction and is greater than half the width of the first touch electrodes.
