With the spread of DA devices, a large number of portable information processing devices have been circulating. And while these portable information processing devices are being reduced in size and weight, they are required to have higher functionality and color display. For this reason, conflicting demands for a liquid crystal display device such as a reduction in size and weight and an increase in density and a large screen have been made.

Conventionally, a liquid crystal display device is composed of a single liquid crystal panel. Therefore, when a high-density large-screen display is performed, the outer shape of the liquid crystal display device is inevitably increased in size.

In addition, a driving IC is provided between two liquid crystal panels.
When C is connected, there is a disadvantage that the interval between the two liquid crystal display devices is widened and a continuous image is difficult to see.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art, reduce the number of driving ICs, and narrow the interval between two liquid crystal display devices to obtain a display that is easy to see even in continuous display. It is another object of the present invention to provide a liquid crystal display device that can be folded to reduce its outer shape when it is carried, and can be expanded to display a large screen when used.
