Claim 18:
19. A display device comprising:
a display panel having a plurality of pixel areas including a first pixel area, a second pixel area and a third pixel area, each of the plurality of pixel areas having a pixel that includes a first electrode, a light emitting layer disposed on the first electrode and a second electrode disposed on the light emitting layer,
a detection unit disposed under the display panel, the detection unit having a sensor that includes a transistor and a detection element electrically connected to the transistor, wherein the detection unit forms a detection area overlapping the detection element, the detection elemment comprising a continuous electrode body;
an optical pattern layer disposed on the sensor and including a plurality of transmission portions and a light blocking portion adjacent to the plurality of transmission portions;
wherein the detection area overlaps at least three of the plurality of transmission portions,
wherein the detection area overlaps both a portion of the first pixel area, a portion of the second pixel area and a portion of the third pixel area;
wherein the first electrodes of the first pixel area, second pixel area and third pixel area overlap at least two of the plurality of transmission portions; and
wherein a number of transmission portions overlapping the first electrodes of the first pixel area, second pixel area and third pixel area, respectively, is less than a number of transmission portions overlapping each of the detection areas.
