Abstract: An optical fingerprint identification system includes a base, a photo sensor, a light emitting layer and a cover. The photo sensor is disposed on the base. The light emitting layer is disposed above the photo sensor, and the light emitting layer includes a light emitting element. The cover is disposed above the light emitting layer. The optical fingerprint identification system further includes a light path adjusting element between the photo sensor and the cover. The light emitting element is disposed away from the light path adjusting element and the photo sensor in a sideway direction that is different from a stack direction of the optical fingerprint identification system.
