• and
• a sensor housing configured to at least partially form a space to include the biometric sensor and comprising a surface in which an opening is formed, and
• wherein the biometric sensor is configured to receive, through the opening, external light passed through the display panel.

An electronic device, comprising:

• a transparent layer;
• a display panel disposed under at least the transparent layer and including pixels;
• a sensor housing disposed under at least the display panel, the sensor housing including at least one side wall and an upper wall in which a first opening is formed;
• a metal inclusive layer disposed between at least the display panel and the upper wall of the sensor housing, wherein a second opening at least partially aligned with the first opening is formed in the metal inclusive layer;
• a biometric sensor mounted on a printed circuit board (PCB), wherein the sensor housing is mounted on the PCB such that the biometric sensor is disposed inside the sensor housing as viewed from above;
• an optical filter disposed inside the sensor housing as viewed from above and attached to a portion of the sensor housing corresponding to the first opening such that the optical filter is disposed apart from both the biometric sensor and the display panel, wherein an air gap is formed between the optical filter and the biometric sensor;
• a circuit element mounted on the PCB and disposed inside the sensor housing as viewed from above, the circuit element electrically connected to the biometric sensor;
• and
• wherein the biometric sensor is configured to receive light emitted from the pixels and reflected from an object positioned on the transparent layer and passing through each of:
• the display panel, the second opening of the metal layer, the first opening of the sensor housing, and the optical filter, and
• wherein, when viewed from above, the first opening defined in the upper wall of the sensor housing has a cross-sectional area which is smaller than a top surface area of the biometric sensor.
