1. An input sensing circuit comprising:
a base film;
a plurality of first sensors disposed on the base film;
a plurality of second sensors disposed on the base film;
a first connection part which electrically connects two first sensors adjacent to each other from among the plurality of first sensors;
a second connection part which electrically connects two second sensors adjacent to each other from among the plurality of second sensors;
an input sensing driver configured to sense a capacitance value between a first sensor of the plurality of first sensors and a second sensor of the plurality of second sensors; and
a pressure sensing part in contact with the first sensor and the second sensor and including a synthetic resin and a conductive material,
wherein the first connection part and the second connection part are spaced apart from each other,
wherein the first connection part and the second connection part overlap each other when viewed in a plan view, and
wherein the pressure sensing part is directly connected to the first connection part via contact holes passing through the two second sensors adjacent to each other.
