Abstract
Provided is a pen sensor for use in detecting an active pen. The pen sensor includes a first layer including a group of first sensor electrodes and a group of first dummy patterns, and a second layer including a group of second sensor electrodes and a group of second dummy patterns. The first dummy patterns and the second dummy patterns are overlaid with each other when viewed from above the pen sensor.

A pen sensor for use in detecting an active pen, the pen sensor comprising:
- a first layer including a plurality of first sensor electrodes and a plurality of first conductor patterns formed of a plurality of first dummy patterns;
- and
- a second layer including a plurality of second sensor electrodes and a plurality of second conductor patterns formed of a plurality of second dummy patterns,
- wherein the plurality of first conductor patterns and the plurality of second conductor patterns are arranged such that a pen signal transmitted from the active pen propagates in a planar direction by way of capacitance generated between the first conductor patterns and the second conductor patterns, and
- wherein the first conductor patterns and the second conductor patterns are overlaid with each other when viewed from above the pen sensor.
