Abstract: A display device with a fingerprint sensing function is provided. The display device includes a display panel and a sensor panel. The display panel includes a plurality of display pixels. The sensor panel is disposed under the display panel. The sensor panel includes a plurality of sensor pixels arranged in an array. The array has a first sensor pitch in a first direction. Each of the sensor pixels includes a sensor. Every two neighboring sensors of the sensors have a first shift pitch in the first direction, and the first shift pitch is not equal to the first sensor pitch.
