Then, as shown in FIG. 4, it is sandwiched between the front cabinet 4 and the rear cabinet 5 of the desktop computer.

Conventionally, the bezels 1, 3 are attached to the cabinets 4, 5 by bending the corners of the front bezel 1 to form a step 6 as shown in FIG. 5, and forming a circular hole 7 in the step 6. It was opened, a screw member was passed through the circular hole 7, and it was attached to the cabinets 4 and 5.

[0004]

Generally, information devices such as notebook type word processors and personal computers are required to be thin as a recent trend.
Along with this reduction in thickness, the thickness of the cabinets 4 and 5 is reduced, so that the strength of the cabinets 4 and 5 is insufficient, and the cabinets 4 and 5 are easily bent during use or in the assembly process. Then, the bezels 1 and 3 are bent as they are, and the module of the liquid crystal display device is directly loaded, and the film carrier (Tape Carrier Package:
(Hereinafter, abbreviated as TCP), which is a cause of disconnection and panel cracking.

On the contrary, in order to maintain the strength of the module of the liquid crystal display device, if it is protected by a thick metal plate or the like, the weight is increased, and the thickness of the module is increased.

In view of the above problems, it is an object of the present invention to provide a liquid crystal display device which can reduce the bending load of the liquid crystal display device while suppressing the weight and reducing the thickness.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, the liquid crystal display device of this embodiment includes a liquid crystal display panel 11, an illuminating device (not shown) for illuminating the liquid crystal display panel 11 from the rear, the liquid crystal display panel 11 and the illumination. A front bezel 13 for pressing the device from the front and a rear bezel 14 for pressing the device from the rear are provided.
At least one of the rear bezel 14 and the rear bezel 14 is provided with fixing means 15 for fixing to the cabinet of the information equipment body.

The liquid crystal display panel 11 is a general thin liquid crystal panel in which a front and rear of a liquid crystal layer are sandwiched by an alignment film and a transparent electrode film, and a transparent plate and a polarizing plate are further laminated.

In order to realize the thinning of the lighting device,
This is a light guide type in which a light source such as a thin cold cathode fluorescent tube (CCFT) is arranged at an end portion, and light from the light source is guided by a thin light guide plate arranged in parallel with the liquid crystal display plate 11.

Each of the bezels 13 and 14 is formed by cutting a metal plate into a frame shape and bending the side portions. The metal plates used for the bezels 13 and 14 are made of, for example, soft aluminum, which can be elastically deformed and has high durability against deformation. The front bezel 13
As shown in FIG. 2, a step portion 16 for providing the fixing means 15 is bent and formed at a corner portion of the.

The fixing means 15 includes the front bezel 13
A circular hole 17 formed in the step portion 16 and a screw 18 screwed into the circular hole 17.

In the vicinity of the fixing means 15, there is provided a relaxing means for relaxing the transmission of the flexure of the cabinet of the information equipment body to the front bezel 13 or the rear bezel 14.

The mitigating means is the periphery of the fixing means 15,
That is, the deformation assisting notch 19 is formed in the vicinity of the circular hole 17 of the step portion 16 of the front bezel 13. The deformation assist notch 1
Reference numeral 9 considers the use of a soft metal plate as the front bezel 13 so that the portion in the vicinity of the circular hole 17 can be elastically deformed so that the flexure is not transmitted to the front bezel 13 even if the cabinet is flexed. I have to. Therefore, the deformation assist notch 19 is formed in an arc shape centering on the circular hole 17. Further, the deformation assist notch 19 and the circular hole 17 are simultaneously formed in the same mold.

When the liquid crystal display device having the above structure is assembled to the information equipment main body, a screw 18 is screwed into a circular hole 17 formed in the step portion 16 of the front bezel 13 and fixed to the cabinet of the information equipment main body.

Here, if the cabinet of the information equipment main body is made thin in response to the market demand, the cabinet and the like are easily bent as a whole. That is, the load applied to the cabinet is transmitted to the circular hole 17 through the screw 18. Then, a load is applied to the peripheral portions of the circular holes 17 of the bezels 13 and 14, and the bezels tend to bend in either direction.

At this time, the deformation assisting notch 19 as a relaxation means blocks the bending of the peripheral portion of the circular hole 17,
It is possible to prevent the load from being transmitted to the portions of the bezels 13 and 14 beyond the deformation assisting notches 19. That is, the bezels 13, 1
Therefore, it is possible to prevent the liquid crystal display panel 11 and the like from bending as a whole, and to prevent the liquid crystal display panel 11 and the like from bending. Therefore, it is possible to prevent disconnection of TCP, panel breakage, and the like.

The present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention.

For example, although the fixing means is attached to the front bezel in the above embodiment, it may be attached to the rear bezel.

In the above embodiment, the light guide type using the light guide plate has been described, but a type not using the light guide plate may be used.

[0024]

As is apparent from the above description, according to the present invention, since the relaxation means including the deformation assisting notch is provided in the vicinity of the fixing means for fixing the bezel to the cabinet of the information equipment body, the cabinet is thin. If any load is applied to the cabinet and the load is transmitted to the circular hole through screws, the deformation-aiding notch as the mitigating means can block the bending of the peripheral portion of the circular hole. . Then, it is possible to prevent the load from being transmitted to the portion beyond the deformation assisting notch of the bezel.

Therefore, the module of the liquid crystal display device can be attached to the cabinet of the information equipment body without applying unnecessary stress. Also,
Even during use, it is possible to relieve external stress that causes trouble to the module and maintain the quality of the module.

As a result, it is not necessary to improve the strength of the module, and the module can be made thinner and lighter.

Further, since it is only necessary to form a deformation assisting notch having a simple shape, it is possible to simultaneously process in the process of punching a circular hole due to the mold structure, so that the manufacturing cost can be suppressed without increasing the mold process. It has an excellent effect that it can be done.
