1. A display device comprising:
a first pixel comprising a light-emitting device;
a second pixel comprising a light-receiving device and a lens overlapping the light-receiving device; and
a first substrate over the lens, a first surface of the first substrate having a light-blocking layer,
wherein the lens is provided in an opening portion of the light-blocking layer on the first surface of the first substrate,
wherein the light-emitting device and the light-receiving device share a common electrode,
wherein a width of the opening portion is greater than a width of a light-receiving portion of the light-receiving device,
wherein a cross section of the lens in a thickness direction including an optical axis has a substantially trapezoidal shape,
wherein a first surface of the lens comprises a leg of the substantially trapezoidal shape and has a convex shape,
wherein a second surface of the lens comprises an upper base of the substantially trapezoidal shape and is provided to face the light-receiving portion,
wherein a third surface of the lens comprises a lower base of the substantially trapezoidal shape and is in contact with the first surface of the first substrate,
wherein a width of the lower base is greater than a width of the upper base, and
wherein the first pixel and the second pixel are provided to be adjacent to each other.
