Claim 14:
15. A display device, comprising:
an upper layer having a fingerprint detection region disposed on a top surface of the upper layer,
wherein the fingerprint detection region receives a light indicating fingerprint information;
an optical layer disposed below the upper layer and having a plurality of transmission holes through which the light penetrating the upper layer passes;
a lower layer disposed below the optical layer and on which the light passing through the transmission holes is received and passes through,
wherein a refractive index of the lower layer is greater than a refractive index of the upper layer; and
a sensor disposed below the lower layer and overlapping the fingerprint detection region,
wherein the sensor receives the light passing through the lower layer,
wherein a thickness of the lower layer is greater than a thickness of the upper layer,
wherein the lower layer further comprises a plurality of first lenses that overlap the transmission holes.
