Electronic device including optical coating layer disposed on cover

An electronic device comprising:

• a cover, forming at least a portion of an exterior of the electronic device, including a transparent portion;
• an optical module including:
• a light-emitting portion, spaced apart from the cover, configured to transmit first light to outside through the transparent portion,
• at least one light-receiving portion, spaced apart from the light-emitting portion, configured to receive second light through the transparent portion, and surrounding an outer periphery of the light-emitting portion, and
• a partition wall disposed between the light-emitting portion and the at least one light-receiving portion;
• a first optical coating disposed on a surface of the transparent portion facing the light-emitting portion;
• a second optical coating, spaced apart from the first optical coating, disposed on the surface of the transparent portion facing the at least one light-receiving portion;
• and
• a light-blocking material disposed between the first optical coating and the second optical coating,
• wherein the first optical coating includes:
• a first pattern,
• a second pattern, spaced apart from an outer periphery of the first pattern by a first distance, surrounding an edge of the first pattern, and having a first width, and
• a third pattern, spaced apart from an outer periphery of the second pattern by a second distance, surrounding an edge of the second pattern, and having a second width.
