According to an embodiment, an electronic device may include: a display including a polarization layer, a biometric sensor positioned to at least partially overlap the display, and an optical member including a light condenser positioned between the display and the biometric sensor. The biometric sensor may include a light receiving unit comprising light receiving circuitry configured to receive light emitted from the display and reflected by an external object. A length of the light receiving unit in a first direction, which is 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.
