20. A display device, comprising:
a display panel;
a sensor disposed on the display panel and including a first area and a second area, the sensor configured to sense light transmitted through the display panel; and
an optical filter disposed between the display panel and the sensor, the optical filter overlapping with the first area and not overlapping with the second area, the optical filter configured to block the light of a first wavelength range,
wherein the first area at least partially surrounds the second area and the optical filter includes at least one opening of a plurality of openings corresponding to the second area, wherein the at least one opening enables light to pass through to reach the second area, wherein the optical filter transmits light of a second wavelength range to the first area and the sensor receives the light of the second wavelength range through the first area, and wherein the plurality of openings are disposed to be spaced apart from each other at a first separation distance on a plane, such that at least one of the plurality of openings corresponds to a detected fingerprint,
wherein the sensor further includes a first sensor pixel and a second sensor pixel, the first sensor pixel is disposed in the first area, and the second sensor pixel is disposed in the second area, and
wherein the first sensor pixel is configured to receive the light of the second wavelength range through the first area overlapping with the optical filter.
