Description of the Related Art Conventionally, electronic devices such as personal computers and word processors with improved portability have a structure in which a main body and a lid are connected by a hinge or the like. When the electronic device is not in use, the lid is closed, and only when the electronic device is in use, the lid is raised to an angle where the display device can be viewed easily. Here, a general configuration of these electronic devices is shown in FIG. 91 is the main body, 9
2 is a lid portion. A display device is installed in the lid part 91, and 1 is a display panel of the display device. The main body 91 is equipped with a circuit board (not shown) equipped with a large number of integrated circuits, a keyboard, and a removable storage element (hereinafter referred to as external memory) such as a memory card or magnetic disk. A magnetic connection device was installed. Here, a case is shown in which a memory card is used as the external memory, and 8 is the memory card, and the state in which it is installed is shown. 61 is a button for ejecting the memory card 8 attached to the connecting device.

[Problems to be Solved by the Invention] However, in the structure of the electronic device of the above-mentioned prior art, a circuit board equipped with a large number of integrated circuits, a keyboard, etc. are installed in the main body, and an external memory is also connected. It was difficult to reduce the thickness of the main body because of the need to install several connecting devices. Furthermore, when the main body is placed on a desk, etc., the thinner the main body becomes, the smaller the gap between the memory card 8 and the desk, etc., becomes, making it difficult to insert the fingers of the hand when inserting or removing the memory card 8, making it easier to operate. There was also the issue of deterioration. The present invention has been made in view of this problem, and by installing a connecting device for connecting an external memory in the gap that occurs in the structure of the display device, the main body of the electronic device can be expanded without increasing the thickness of the lid of the electronic device. This is intended to prevent deterioration in operability by easily reducing the thickness and allowing external memory to be attached and removed at the lid. The purpose of the present invention is to provide a display device that can reduce the thickness of an electronic device that uses a display device and an external memory, and improve the operability of the external memory, and to provide a display device that can reduce the thickness and improve the operability of the external memory by using this display device. The objective is to provide electronic devices with improved performance.

[Example 1] The configuration of a display device of the present invention will be explained using an example. Note that a liquid crystal display device is used as an example of the display device. FIG. 1 is a diagram showing the configuration of a liquid crystal display device according to this embodiment. 4A is a side view of the structure of the liquid crystal display device, and FIG. 1B is a view from below. In the figure, 1 is a liquid crystal panel. Reference numeral 2 denotes an integrated circuit comprising a signal electrode drive circuit for driving signal electrodes (not shown) of the liquid crystal panel 1, mounted on a flexible circuit board. A plurality of X drivers 2 (hereinafter referred to as X drivers) are usually arranged as shown in the figure. 3 is a bus board that supplies predetermined signals and power to the X driver 2; (hereinafter referred to as X-PCB) 4 is a scanning electrode (

It is connected to 4. Here, X driver 2 and Y driver 4
The angle when connecting one end to LCD panel 1 is not necessarily 1.
The angle does not have to be 80 degrees, and may be 90 degrees, for example. The above configuration is exactly the same as that of the prior art. and,
6 is a connection device for connecting the memory card to. (Hereafter referred to as socket) Socket 6 is X driver 2,
The X-PCB 3, the Y-driver 4, and the Y-PCB 5 are arranged approximately at the center of the back surface of the liquid crystal panel 1 where the X-PCB 3, Y-driver 4, and Y-PCB 5 are not arranged. Here, 61 is the memory card eject button, 6

It doesn't matter if it is connected to The above is the configuration.

[0007] Here, the X driver 2 and the Y driver 3
The thickness of the X-PC is approximately 1 mm to 1.5 mm.
The thickness of B3 and Y-PCB is 1.6 mm. Therefore,
Maximum total thickness of X driver 2 and X-PCB3, Y driver 4
Therefore, the maximum total thickness of the Y-PCB 5 is approximately 3 mm. Here, the thickness of the memory card is approximately 3.2 mm, and the thickness of the socket 6 is a little less than 4 mm, which means that the thickness of the memory card is approximately 3.2 mm, and the thickness of the socket 6 is approximately 4 mm.

In this embodiment, a liquid crystal display device is used as an example of a display device, but a plasma display device, an electroluminescence display device, etc. can also have similar effects. Furthermore, although a memory card is used as an example of the external memory, a magnetic disk read/write device may also be used. In the case of this read/write device, the thickness is larger than the total thickness of the mechanical parts of the display device due to the driving parts, so the total thickness of the display device is slightly thicker, but the thickness increases by the total thickness of the mechanical parts of the display device. It can be prevented. Also, in this case, the angle when connecting one end of the driver 2 and Y driver 4 to the liquid crystal panel 1 is 90°.
By doing so, it is possible to arrange the read/write device in almost the entire width of the liquid crystal panel 1.

This is the Mori card eject button 61. Reference numeral 8 indicates a memory card inserted into the memory socket 6 (not shown).

[0010] Because of the above configuration, the main body part 71
There is no need to install a device to connect an external memory to the device, and the device can be made thinner. Further, although a device for connecting an external memory is installed on the lid portion 72, even if a device for connecting an external memory is installed as explained in the first embodiment, the lid portion 72
There is no need to increase the thickness. Therefore, the entire electronic device 7
