Claim 17:
18. A display device, comprising:
a window on which a fingerprint detection region in which fingerprint information is detected is defined;
an optical layer disposed below the window and in which at least one transmission hole overlapping the fingerprint detection region is defined;
a protection layer disposed below the optical layer,
wherein a refractive index of the protection layer is greater than a refractive index of the window; and
a sensor disposed below the protection layer and overlapping the fingerprint detection region,
wherein a distance from the optical layer to the window is less than a distance from the optical layer to the sensor,
wherein the protection layer comprises:
a first protection layer having a first refractive index; and
a second protection layer disposed below and in direct contact with the first protection layer and having a second refractive index greater than the first refractive index,
wherein the protection layer further comprises:
a lens that overlaps the transmission hole.
