Abstract: A display device includes a display panel including first and second areas. The display panel includes: pixels located in the first and second areas and connected to scan lines, and including light emitting elements; first light sensors located in the first area and connected to the scan lines, and including first light receiving elements; and second light sensors located in the second area and connected to the scan lines, and including second light receiving elements. The first and second light sensors are connected to a reset line. A reset signal of a first pattern is applied to the reset line in a first mode in which sensing information is generated based on the first light sensors. The reset signal of a second pattern is applied to the reset line in a second mode in which sensing information is generated based on the second light sensors.
