Wearable device

A wearable device comprising:

• a body including a plurality of segment members that are connected sequentially to be rotatable, wherein the body transforms between an annularly bent state and a flat state;
• a flexible display device supported on the body;
• a bistable spring that provides elasticity in a direction of bending into the annularly bent state and retentivity to maintain the flat state;
• and
• slots provided in the plurality of segment members to pass the bitable spring therethrough, wherein the slots comprise a top supporting portion and a bottom supporting portion, each of which supports a top surface and a bottom surface of the bistable spring;
• wherein a gap between the top supporting portion of the slot and the bottom supporting portion of the slot is greater at both ends than a center portion in an alignment direction of the plurality of segment members.
