摘要：
A fingerprint sensor includes: a substrate; a circuit element layer on a first surface of the substrate and including a plurality of conductive layers; a light emitting element layer on the circuit element layer and including light emitting elements and a light shielding layer; and a light sensor layer on a second surface of the substrate and including light sensors, wherein the light shielding layer includes contact holes exposing first electrodes of the light emitting elements, and first opening portions exposing a portion of the circuit element layer, and the circuit element layer includes second opening portions formed in the plurality of conductive layers and includes a light transmission hole of which at least a portion overlaps the first opening portions.
