Abstract

A plurality of panels include: a display panel; and a protective panel that is disposed outside the display panel, and includes a transparent substrate and an outer hard coating layer and an inner hard coating layer that are respectively formed on an outer surface and an inner surface of the transparent substrate, and each have a hardness greater than a hardness of the transparent substrate. A thickness of the outer hard coating layer is greater than a thickness of the inner hard coating layer, and a stress neutral surface of the flexible display device is configured so that a compressive stress is applied to the inner hard coating layer when the flexible display device is bent.

Description

technical field [0001] Methods and apparatuses according to example embodiments relate to a flexible display device that may be flexibly bent. Background technique [0002] Portable and foldable devices (eg, mobile devices), such as communication terminals, game consoles, multimedia devices, portable computers, or photographing devices, may include a display device that displays image information and an input unit such as a keyboard. To improve portability, mobile devices may have a foldable structure that can be folded into a smaller size. In a foldable mobile device, two bodies are connected to each other via a foldable structure. Since conventional displays cannot be folded, conventional display devices can only be located on one of the two bodies. Therefore, it is difficult to apply a large display device to a mobile device having a foldable structure. [0003] Flexible displays have been applied to mobile devices with foldable structures. Since the flexible display ...
