More particularly, the present invention relates to a flexible display device capable of stably maintaining a shape of a display device when the display device is installed upright, .

With the development of technology, utilization of portable terminals such as digital camera mobile phones, digital cameras and camcorders has been increasing, researches have been actively carried out to combine various functions such as communication functions and MP3 functions in various portable terminals in order to meet various demands of consumers have.

Of these, the beam projector can project a large image of usually 8 to 50 inches. The beam projector has the advantage of being able to utilize all the surrounding environment on the screen without using the screen (display device) and the advantage that the image can be seen largely, but the character recognition is not fully recognized.

In order to solve the above problems, a beam projector having a touch screen has been developed.

The beam projector uses a touch screen instead of a conventional screen to project an image of the beam projector onto a torch screen and touches the projected touch screen and detects it. The beam projector having the touch screen has already been disclosed in Japanese Patent Application Laid-Open No. 2004-212488 (July 29, 2004).

However, the conventional beam projector having a touch screen mainly uses a large touch screen or has a fixed size of the touch screen, which makes it difficult to carry the touch screen.

In addition, the fixed-size touch screen has been widely used in various fields, and has been limited in its size in a portable beam projector for simplicity of portability. Therefore, in order to overcome this point, a flexible screen technology capable of providing a variety of simplicity of portability and size has been developed.

However, since the conventional flexible touch screen is folded like paper, there is a disadvantage that the folded portion of the flexible touch screen is damaged, the power line and the communication line are damaged, and when folded, it is difficult to maintain the folded form .

Therefore, there is a high need for a flexible screen that is easy to carry without folding the flexible screen while solving such conventional problems.
