Abstract

A display device includes 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, and a sensor. A refractive index of the protection layer is greater than a refractive index of the window. A distance from the optical layer to the window is less than a distance from the optical layer to the sensor.
