Abstract

The plurality of panels includes a display panel and a protective panel, wherein the protective panel is arranged outside the display panel and includes a transparent substrate, and an outer hard coat layer and an inner hard coat layer; the outer hard coat layer and the inner hard coat layer are respectively formed on on the outer and inner surfaces of the transparent substrate, and each has a hardness greater than that of the transparent substrate. The thickness of the outer hard coat layer is greater than the thickness of the inner hard coat layer, and the stress-neutral surface of the flexible display device is configured such that a compressive stress is applied to the inner hard coat layer in response to bending of the flexible display device.

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 ...
