Elastic member and display device comprising same

An elastic member foldable with respect to a folding axis, the elastic member comprising:

• a first region and a second region,
• wherein a first direction is defined as a width direction of the elastic member and is a same direction as a direction in which the folding axis extends and a second direction is defined as a longitudinal direction of the elastic member and is a direction perpendicular to the direction in which the folding axis extends and the first direction,
• wherein the first region is defined as a folding region that is folded with the first direction as the folding axis, and the second region is defined as an unfolding region,
• wherein the elastic member includes a first layer, a second layer disposed on the first layer, and a third layer disposed between the first layer and the second layer,
• wherein the first layer includes a metal,
• wherein the second layer includes a base material and fibers disposed inside the base material,
• wherein the fibers provided in the second layer are disposed in the second layer to extend in the second direction, which is a direction perpendicular to the direction in which the folding axis extends and the first direction,
• wherein the third layer is an adhesive layer disposed between the first layer and the second layer,
• wherein the first layer includes a first void disposed in the first region of the first layer, and
• wherein the third layer includes a second void disposed in the first region of the third layer.
