Abstract: A display device reduces or minimizes a stress applied to a display panel in a folded state. The display device includes a display panel including a bendable area; and a panel support portion combined to the display panel and including a multi-joint member to support the bendable area, and the multi-joint member includes: a plurality of hard material portions sequentially arranged in a first direction, mutually combined to be rotated with respect to one another, and including a first surface arranged toward the bendable area; and a soft material portion contacting the first surface and fixed to the plurality of hard material portions.

Abstract: A foldable display device includes a display panel and a panel supporting unit. The display panel has a first surface in which a display unit is positioned and a second surface opposite to the first surface and including a bendable region. A panel supporting unit faces the second surface and is coupled to the display panel. The panel supporting unit includes a plurality of link members arranged in parallel along a first direction by corresponding to the bendable region of the display panel in an unfolded state, each of the plurality of link members respectively having a first supporting surface facing the display panel and coupled to be rotated about two rotational axes in a folded state. The two rotational axes of each of the plurality of link members are separated from the first supporting surface in a direction from the second surface toward the first surface.
