Abstract
Provided is an electronic device including: a biometric information sensing layer including a sensor; an optical pattern layer disposed on the biometric information sensing layer, and including a plurality of transmission parts and a light shielding part; and a display layer disposed on the optical pattern layer. When a fill factor (FF) of the sensor, which is a ratio of the amount of light received by the sensor to the total amount of light incident onto the sensor, is about 10% to about 70%, a field of view (FOV) of light incident onto the sensor is about 15° to about 30°.
