Abstract: A flexible display device includes a flexible substrate including a display area and a non-display area, an organic light emitting element disposed on the flexible substrate, and a cover member disposed on the organic light emitting element and including a plurality of thin glass plates and an adhesive layer between the plurality of thin glass plates, wherein each of the plurality of thin glass plates has a thickness of 0.1 mm or less. According to an aspect of the present disclosure, it is possible to provide a flexible display device that simultaneously satisfies folding characteristics and impact resistance while maintaining high surface characteristics of glass itself by using a cover member in which the plurality of thin glass plates are stacked.
