1. A display device, comprising:
a fingerprint sensor layer that receives light reflected by an external object;
a substrate disposed on the fingerprint sensor layer;
an optical pattern layer disposed on the substrate and that includes a light blocking portion and a light transmitting portion that passes through the light blocking portion in one direction;
a light emitting element layer disposed on the optical pattern layer;
a first lens layer having a first refractive index and that is disposed in one of an area between the optical pattern layer and the light emitting element layer or an area between the optical pattern layer and the substrate; and
a planarization layer disposed on the first lens layer and that has a second refractive index less than the first refractive index,
wherein the first lens layer includes a first inclined surface,
the first lens layer includes a flat upper surface and a flat lower surface parallel to the upper surface,
the first inclined surface is a flat surface that is disposed between the upper surface and the lower surface,
the flat lower surface is disposed between the flat upper surface and the fingerprint sensor layer, and
a first length of the flat upper surface is shorter than a second length of the flat lower surface in a direction in which a plane where the substrate is disposed extends.
