1. An arm-worn electronic device comprising:
a structure body comprising a curved portion;
a display portion with a curved shape in both first and second states of the arm-worn electronic device; and
a secondary battery with a curved shape in both the first and second states of the arm-worn electronic device,
wherein the secondary battery and the display portion overlap each other with the curved portion of the structure body therebetween,
wherein the arm-worn electronic device further comprises a first region where the secondary battery and the display portion overlap each other and a second region where the secondary battery and the display portion does not overlap each other,
wherein each of the first region and the second region has different curvature radiuses between the first state and the second state of the arm-worn electronic device, and
wherein the second region has a larger difference of curvature radiuses between the first state and the second state of the arm-worn electronic device than the first region.
