Abstract

A display device includes a display panel partitioned into pixel rows, and the display panel includes pixels and fingerprint sensors arranged on the pixel rows, a panel driver for driving the pixels, and a sensor driver for detecting a user fingerprint, based on a sensing signal from the fingerprint sensors. The fingerprint sensors may include first fingerprint sensors on an odd-numbered pixel row and second fingerprint sensors on an even-numbered pixel row, and an area of an anode electrode of a light receiving element in each of the first fingerprint sensors may be equal to an area of an anode electrode of a light receiving element included in each of the second fingerprint sensors.
