Abstract

A foldable display device includes a flexible display panel, a case supporting the flexible display panel, a bonding member fixing the flexible display panel to the case. The case includes a hinge portion, and supports respectively coupled to the hinge portion at opposing sides of the hinge portion. The flexible display panel includes a bendable area corresponding to the hinge portion, and planar areas respectively at opposing sides of the bendable area and corresponding to the supports of the case. The bonding member is between a support of the case and the corresponding planar area of the flexible display panel, and is displaceable with respect to the support along one of a thickness direction and a width direction of the flexible display panel when the flexible display panel is folded.

a bendable area corresponding to the hinge portion,
a first planar area and a second planar area respectively at opposing to sides of the bendable area and respectively corresponding to the first support and the second support;
a first bonding member disposed overlapping both the first support and the first planar area along a thickness direction of the flexible display panel, and
a second bonding member disposed overlapping both the second support and the second planar area along the thickness direction of the flexible display panel,
wherein the first bonding member has a first bonding force,
wherein the second bonding member has a second bonding force,
wherein the first bonding force is different from the second bonding force,
wherein at least one of a first distance between the first planar area and the first support, and a second distance between the second planar area and the second support has a different value before and after the flexible display panel is folded, and
wherein the first distance and the second distance are defined in a direction perpendicular to the flexible display panel.
