1. An electronic device comprising:
a display panel including red-light emitting elements, green-light emitting elements, blue-light emitting elements, and light receiving elements that are spaced from each other, wherein the blue-light emitting elements emit blue light in a biometric information measurement mode of the electronic device, wherein the light receiving elements receive at least one of red light and green light in the biometric information measurement mode of the electronic device after the blue-light emitting elements have emitted the blue light, and wherein the light receiving elements generate electrical signals in response to the at least one of the red light and the green light; and
a biometric information measurement module electrically connected to the display panel and configured to generate biometric information about a skin of a user based on the electrical signals,
wherein the display panel comprises a display area including a first area and a second area, a non-display area surrounding the display area,
wherein the first area includes first red-light emitting elements, first green-light emitting elements, first blue-light emitting elements and a first light receiving element, and the second area includes a plurality of second blue-light emitting elements and a second light receiving element,
wherein the plurality of the second blue-light emitting elements includes a first-second blue-light emitting element, a second-second blue-light emitting element, a third-second blue-light emitting element and a fourth-second blue-light emitting element,
wherein the second light receiving element is interposed between the first-second blue-light emitting element and the second-second blue-light emitting element along a first direction, and is interposed between the third-second blue-light emitting element and the fourth-second blue-light emitting element along a second direction perpendicular to the first direction, and
wherein the second area does not include red-light emitting elements and green-light emitting elements.
