1. A detection module, the detection module comprising:
a substrate including a detection area and a non-detection area disposed around the detection area;
a detector disposed on the substrate to detect an external signal;
a sensor driving circuit disposed on the substrate to drive the detector;
a light shielding layer disposed throughout the detection area of the substrate to overlap the sensor driving circuit and the detector, the light shielding layer being configured to block an external light from entering the sensor driving circuit and to receive a light blocking voltage,
a connection electrode disposed on and electrically connected to the light shield layer; and
a power supply line to supply the light blocking voltage to the light shielding layer through the connection electrode, the power supply line being disposed on the connection electrode and overlapping the light shield layer in the detection area.
