The present invention relates to a bending mechanism and a display device, and more particularly to a bending mechanism and a flexible screen display device applied to a flexible display screen.

Existing manufacturers of portable display devices such as smart phones and tablet computers have increased the display area of the display screen in order to provide consumers with a better experience. Since the existing smart phone uses a non-bendable display, when the size of the display reaches 4 吋 to 6 吋 or more, the size of the smart phone becomes larger, making it impossible for the user to utilize one hand. It is extremely inconvenient to hold the operation and carry it. To this end, some manufacturers have begun to develop a portable display device using a flexible display screen, and its development concept is to fix the flexible display screen in the folding mechanism, and the user can utilize the flexible display screen when the user does not need to view the flexible display screen. The folding mechanism folds the portable display device into a relatively small volume type; and when the user spreads the folding mechanism, the flexible display screen can be flattened into a large-sized display surface. However, there are many problems with this development component, the biggest problem of which is that if the flexible display screen is directly attached to the folding mechanism, the flexible display screen may be crushed by the folding mechanism.
