Abstract

A display device includes: a display module configured to display an image; and a detection sensor disposed on the display module, wherein the detection sensor includes a base layer, a biometric sensing layer, an optical pattern layer, and a sensing dielectric layer, wherein the biometric sensing layer is disposed on the base layer, wherein the optical pattern layer is disposed on the biometric sensing layer, and the sensing dielectric layer is disposed on the optical pattern layer. The optical pattern layer includes: a plurality of transmission parts that provide the biometric sensing layer with light that is externally incident through the display module; and a light-shield part that at least partially surrounds the plurality of transmission parts. The light-shield part includes a plurality of light-shield patterns that are recessed in a direction toward the base layer.
