1. A display device comprising:
a display panel partitioned into a plurality of pixel rows, the display panel including a plurality of pixels and a plurality of fingerprint sensors, which are arranged on the plurality of pixel rows;
a panel driver configured to drive the plurality of pixels; and
a sensor driver configured to detect a fingerprint of a user, based on a sensing signal generated in the plurality of fingerprint sensors,
wherein the plurality of fingerprint sensors includes a plurality of first fingerprint sensors arranged on an odd-numbered pixel row and a plurality of second fingerprint sensors arranged on an even-numbered pixel row,
wherein an area of an anode electrode of a light receiving element included in each of the plurality of first fingerprint sensors is equal to an area of an anode electrode of a light receiving element included in each of the plurality of second fingerprint sensors, and
wherein a shape of the anode electrode of the light receiving element included in each of the plurality of first fingerprint sensors is different from a shape of the anode electrode of the light receiving element included in each of the plurality of second fingerprint sensors.
