Electronic device and method for obtaining biometric information thereof

An electronic device comprising:

• a display including a polarization layer;
• a biometric sensor positioned to at least partially overlap the display;
• and
• an optical member comprising a light condenser positioned between the display and the biometric sensor,
• wherein the biometric sensor includes a light receiving unit comprising light receiving circuitry configured to receive light emitted from the display and reflected by an external object,
• wherein a length of the light receiving unit in a first direction, is the first direction being a polarization axis direction of the polarization layer, is greater than a length of the light receiving unit in a second direction crossing the first direction,
• wherein the optical member includes a plurality of lenses, and
• wherein a location of a principal plane of the optical member in the first direction is different from a location of principal plane of the optical member in the second direction.
