    Abstract: A bending test apparatus includes a jig including first to third supporting members arranged in a first direction; a shaft member including a first shaft, a second shaft, and a third shaft extending in a second direction intersecting the first direction and respectively connected to the first to third supporting members; a driving member connected to the first shaft and providing a rotation force to the first shaft; a sliding member including a first slider and a second slider respectively connected to the second shaft and the third shaft; and a rail member extending in the first direction and guiding movements of the first slider and the second slider. When the first shaft rotates the first supporting member in a first rotation direction, the second and third supporting members rotate in a second rotation direction opposite to the first rotation direction.

    Abstract: A display device includes a display panel including a bending area that is bendable along an axis extending in a first direction, and a panel support portion that supports the display panel in the bending area. The panel support portion includes a plurality of joint members, a plurality of rotational angle limiting members, and a plurality of connecting members. The joint members are sequentially arranged and support the display panel. Each joint member is rotatable about two rotation axes. The rotational angle limiting members are coupled to the joint members and limit rotational angles of the joint members. Each connecting member is coupled to a pair of the rotational angle limiting members disposed at a pair of adjacent joint members. The rotational angle limiting members included in the pair of rotational angle limiting members contact each other and are fixed to an inner portion of the corresponding connecting member.
