Sensor for detecting pen signal transmitted from pen

A sensor for detecting a pen signal transmitted from a pen, comprising:

• a touch sensor having first electrodes extending in a first direction and second electrodes extending in a second direction perpendicular to the first direction, which form a rectangular-shape position detection area and are configured to respectively receive the pen signal;
• first routing traces which connect some of the first electrodes to first flexible printed circuit (FPC) connector terminals that are arranged outside of the position detection area, the first routing traces extending toward one end of the first direction;
• and
• second routing traces which connect others of the first electrodes to second FPC connector terminals that are arranged outside of the position detection area, the second routing traces extending toward another end of the first direction, such that the first routing traces and the second routing traces extend in opposite directions from the first electrodes along the first direction.
