Recently, as the penetration rate of portable wireless terminals increases, additional functions that are suitable for the user's taste are required for the portable terminal, as well as simple functions of wireless communication.

In response to these demands, portable terminals have evolved from a general bar type to a flip type, a flip up type, a folder type, and the like. To achieve.

This is because the folder type terminal has enough space for adopting the wide LCD module as the display device, and because the portable terminal is folded in half, the portability is superior to other terminals.

On the other hand, it is possible to have a display device having a wide LCD module of a similar size as a folder type terminal, and at the same time, a slide type terminal capable of contributing to the miniaturization of the terminal is known.
