Abstract
The fingerprint sensor may include: a light transmitting hole array layer including a plurality of light blocking patterns having a plurality of light transmitting holes to form light transmitting paths of light rays; a sensor layer including a plurality of photo sensors configured to sense light rays that pass through the light transmitting holes and are incident on the sensor layer; and metal patterns configured to apply electrical signals to pixels or the light blocking patterns. A gap between the light blocking patterns may overlap with at least some of the metal patterns.
