Electronic device having fingerprint sensor

An electronic device comprising:

• a window configured to form a first surface of the electronic device facing a first direction, wherein at least a part of the first surface is a display area, and at least a part of the display area is a fingerprint sensing area;
• a display panel disposed under the display area in a space between the first surface and a second surface of the electronic device facing a second direction opposite the first direction and configured to output an image through the display area;
• a touch sensor disposed under the display area in the space and configured to output a signal in response to contact of a conductive object on the display area;
• and
• a fingerprint sensor disposed under the fingerprint sensing area in the space and configured to output a signal in response to contact of a fingerprint on the fingerprint sensing area,
• wherein the fingerprint sensor is disposed on part of a bottom surface of the window,
• wherein the part of the bottom surface of the window is a region located under the fingerprint sensing area,
• wherein the bottom surface of the window faces a direction opposite the display area,
• wherein the part of the bottom surface of the window is lower than another part of the bottom surface of the window when viewed from the second surface, and
• wherein a substrate on which the fingerprint sensor is disposed is attached to the part of the bottom surface of the window.
