Abstract: A jig for testing a flexible panel includes first and second flat panel frames, and a first hinge part between the first flat panel frame and the second flat panel frame to allow the first flat panel frame and the second flat panel frame to be subjected to folding. The first hinge part includes a first gear arm, a second gear arm engaged with the first gear arm, and a first gear housing covering at least a portion of the first gear arm and at least a portion of the second gear arm. A panel exposing area concavely bent toward the inside of the first gear housing may be defined in the first gear housing, and in case that the first flat panel frame and the second flat panel frame are folded, the panel exposing area of the first gear housing exposes a side of the display member.

Abstract: A display device includes a display panel that is foldable based on a folding line extending in a first direction. A support member is on a first surface of the display panel and includes first and second non-folding parts, a folding part disposed therebetween which is stretched when the display panel is folded and a groove disposed on the folding part. The folding part includes slits and bars disposed between the slits. The support member includes fiber yarns extending in the first direction and fiber yarns extending in a second direction crossing the first direction. The fiber yarns extending in the first direction and the fiber yarns extending in the second direction are alternately stacked along a thickness direction of the support member. The slits and the fiber yarns on an upper surface of the folding part exposed by the groove have a same extension direction as each other.

Abstract: A display device includes a first plate, a second plate disposed on the first plate, and a display module disposed on the second plate. The display module includes a first non-folding area, a second non-folding area, a first folding area disposed between the first non-folding area and the second non-folding area, and a second folding area disposed between the first non-folding area and the second non-folding area. The first folding area is configured to fold so as to bring the first non-folding area and the second non-folding area to face one another in a first use form. The second folding area is configured to fold so as to bring the first non-folding area and the second non-folding area to face away one another in a second use form.
