DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an LCD (liquid crystal display), and more particularly to a combination arrangement of an LCD cell and a circuit board.

[0002]

2. Description of the Related Art CRTs have been used as broadcast televisions, computers or various monitor outputs. In recent years, various flat displays have been used for these displays, contributing to miniaturization and thinning of devices. doing.
In particular, such a flat display is indispensable for making a computer portable and compact, and various types of liquid crystal displays, plasma displays, fluorescent display panels, and the like have been proposed. However, in general, a liquid crystal display, that is, a liquid crystal display device which has a small power consumption and obtains a stable display operation is widely used. Good computer is obtained.

FIG. 6 shows a conventional general liquid crystal display device, in which a well-known LCD cell 10 is connected to a display circuit board 1.
2 and fixed.

The LCD cell 10 itself has a structure in which a liquid crystal is sealed between two glass plates forming a common electrode and a segment electrode, and a polarizing plate is usually provided on the outer surfaces of both glass plates.

A predetermined display circuit element is mounted on the back side of the circuit board 12 so as to supply a predetermined drive voltage to the common electrode and the segment electrode of the LCD cell 10. A desired driving voltage is supplied to the LCD cell by connecting the pins with a pin or by using a conductive rubber or the like, and an arbitrary display operation is achieved.

Conventionally, an I cell is directly connected to an LCD cell.
It has been proposed to reduce the size of the device by mounting a C circuit. For example, as a COG (chip-on-glass) method, an IC is directly mounted on the glass surface of an LCD cell to reduce the size and thickness.

Another conventional method is TAB.
It has been proposed to integrate an LCD cell and an IC circuit mounted on an FPC by a method.

[0008]

However, in such a conventional liquid crystal display device, as is apparent from FIG. 6, the LCD cell 10 and the display circuit board 12 are superimposed as a whole, so that the size and thickness of the liquid crystal display device are reduced. However, there is still a problem that the thickness of a portable computer which is strictly required is large.

[0009] Therefore, it has been the actual situation that the thickness of the display has not yet been reduced to a satisfactory level as a display incorporated in the lid of the above-mentioned computer which is carried in an attache case or the like.

[0010] In the conventional COG method described above, I
In order to reduce the input resistance of C, a metal film is required not only for the ITO of the LCD cell but also for the input pattern to the IC, and as a result, there is a problem that the cost of the LCD cell increases. In addition, in this COG method, if even a part of the IC mounted on the LCD cell becomes defective, the LCD cell itself must be discarded, and a defect is found after mounting the IC including such a defective part. in case of,
There is a problem that the production yield is remarkably reduced, and further, such an integrated cell requires a substrate for input.

Also, in the conventional TAB system which is another conventional system, it is necessary to form bumps for connecting the LCD cells, which increases the FPC cost and requires an input substrate. .

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide an improved liquid crystal display device which does not deteriorate the characteristics of the display device while further reducing the thickness of the liquid crystal display device. is there.

The pressing directly LCD cell from the display front, and supports against the apparatus housing.

By supporting the LCD cell so that the upper receiving plate member does not cover a polarizing plate having a predetermined thickness,
The thickness of the liquid crystal display device can be reduced accordingly. In particular, if the thickness of the upper receiving plate member is substantially equal to that of the polarizing plate, the contribution to the reduction in the thickness of the device is increased. Further, since the area of the LCD cell not covered by the polarizing plate is a non-display area that does not contribute to normal display, even if such a non-display area is pressed by the upper receiving plate member, the effective display area is not affected. Without this, it is also possible to prevent the light from the light source arranged behind the LCD cell from leaking to the display surface side (display front side) due to the absence of the polarizing plate. In addition, the LCD cell
The device is made thinner by directly holding it with a plate member.

A further feature of the present invention is that a cushion for supporting the cell end region of the LCD cell from the display back side of the device is arranged in a gap between the device housing and the LCD cell. is there.

For example, when at least a part of the circuit board is overlapped with the LCD cell in the vicinity of the cell edge region of the LCD cell, the cushion member is placed in the vicinity of the overlapped region. It is arranged in a gap between the device housing and the LCD cell. The cushion member is, for example, rubber.

When the circuit board is disposed on the display back side of the LCD cell, a circuit board superposed on the LCD cell is interposed between the LCD cell and the cushion member.

The LCD cell, which is held down from the front side of the display by the upper receiving plate member and pressed against the display housing, is supported by the cushion member from the rear side thereof, so that the LCD cell formed using a glass substrate or the like can be used. Damage can be prevented. In particular, when the circuit board and the LCD cell are superposed and arranged in the cell edge region, these regions are supported from the back side by using a cushion member, so that the LCD cell is supported.
Damage to both the cell and the circuit board can be prevented. In addition, the stress applied to the housing of the liquid crystal display device can be absorbed by the cushion member, which contributes to the improvement of the reliability of the device.

Still another feature of the present invention is a liquid crystal display device in which an LCD cell formed by enclosing liquid crystal between two substrates is housed in a device housing, and a support is provided in the device housing.

Pressing from the front side, this circuit board is to support against the LCD cell in the device housing.

[0026] With this configuration, without separately providing a special member it is possible to support the LCD cell against the device housing.

Further, the LCD cell is supported from the display back side in the gap between the device housing and the LCD cell near the cell end region where the LCD cell and the circuit board are overlapped and arranged. If you place a cushion member,
The LCD cell and the circuit board can be prevented from being damaged, and the stress resistance of the device can be increased.

Further, if a display circuit element is mounted on the display back side of the circuit board and a shield member is disposed on the display front side of the circuit board, the display circuit element generating electromagnetic noise can be shielded. It can be easily shielded by a member (for example, a shield metal plate).
