description According to embodiments of the present invention, a touch sensor comprises: a base layer including a first area and a second area; a plurality of touch sensing unit electrodes disposed on the first area of the base layer; a fingerprint sensing eletrode layer disposed on the second area of the base layer, and including first fingerprint sensing unit electrodes and second fingerprint sensing unit electrodes disposed on different layers; and dummy electrodes separated from the touch sensing unit electrodes and formed to overlap the touch sensing unit electrodes in a plane direction. The electrode visibility may be reduced through the dummy electrodes. 본 발명의 실시예들의 터치 센서는 제1 영역 및 제2 영역을 포함하는 베이스 층, 베이스 층의 제1 영역 상에 배치되며 복수의 터치 센싱 단위 전극들, 베이스 층의 제2 영역 상에 배치되며 서로 다른 층에 배치된 제1 지문 센싱 단위 전극들 및 제2 지문 센싱 단위 전극들을 포함하는 지문 센싱 전극층, 및 터치 센싱 단위 전극들과 이격되어 터치 센싱 단위 전극들과 평면 방향에서 중첩되도록 형성된 더미 전극들을 포함한다. 더미 전극을 통해 전극 시인을 감소시킬 수 있다.
