FLEXIBLE DISPLAY DEVICE

摘要

A flexible display device including a plurality of panels bonded to each other by bonding layers is disclosed. A plurality of panels include a display panel that displays an image; and a protective panel that includes a transparent substrate, and an outer hard coating layer and an inner hard coating layer formed on an outer surface and an inner surface of the transparent substrate and having a hardness higher than that of the transparent substrate, and that is situated outside the display panel. The thickness of the outer hard coating layer is larger than the thickness of the inner hard coating layer, and a stress neutral surface of the flexible display device is determined such that a compression stress is applied to the inner hard coating layer when the flexible display device is bent. The present invention provides a flexible display device that may reduce distortion of an image while having stable folding characteristics.
