A display device includes: at least one fingerprint sensor configured to sense a fingerprint of a user corresponding to a first fingerprint sensing area of a display panel; an image generator configured to generate a target fingerprint image based on a sensing signal output from the at least one fingerprint sensor; an image analyzer configured to detect a defect in the target fingerprint image based on at least one first fingerprint image corresponding to the first fingerprint sensing area and at least one second fingerprint image corresponding to a second fingerprint sensing area spaced apart from the first fingerprint sensing area of the display panel; and an image corrector configured to correct the defect in the target fingerprint image.
