Foldable Assembly and Foldable Electronic Device

A foldable electronic device, comprising:

• a first body;
• a second body;
• a display screen comprising a bendable part comprising an end part and a first end surface, wherein the end part extends from the first end surface by a first distance in a first direction;
• and
• a rotating shaft comprising a substrate disposed between the first body and the second body,
• wherein the substrate comprises a first surface and a second end surface,
• wherein the first surface is a side surface of the substrate facing the bendable part,
• wherein the first surface comprises a support part and a recessed part,
• wherein the recessed part corresponds to the end part,
• wherein the recessed part comprises a first end facing the second end surface,
• wherein there is a second distance between the first end and the second end surface,
• wherein in a second direction there is a first gap between the bendable part and the recessed part and there is a second gap between the bendable part and the support part,
• wherein the first gap is greater than the second gap,
• wherein the first direction is an axial direction of the substrate, and
• wherein the second direction is a thickness direction of the substrate.
