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.
Claims18
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 first protection layer and the second protection layer are in continuous direct contact with each other in an area below the optical layer and overlapping the at least one transmission hole, and in an area below the optical layer and between the at least one transmission hole and an adjacent transmission hole defined in the optical layer.
