Claim 19:
20. A fingerprint sensor, comprising:
a substrate;
a light sensing element that includes a sensing electrode disposed on the substrate and a common electrode disposed on the sensing electrode;
a light-blocking conductive layer that includes light transmitting holes and is disposed on the common electrode;
a light guide portion that guides light and is disposed on the light-blocking conductive layer;
a fingerprint pad disposed on a side of the substrate;
aground line connected to the fingerprint pad; and
a connection electrode connected to the ground line,
wherein the light-blocking conductive layer is connected to the connection electrode through a connection contact hole, and
wherein the light guided by the light guide portion is incident on the light sensing element through at least one of the light transmitting holes.
