[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device, and more particularly to a liquid crystal display element mounting structure applied when mounting a liquid crystal display element in a cabinet.

[0002]

2. Description of the Related Art Conventionally, when mounting a liquid crystal display element in a cabinet whose mounting position does not match, several kinds of mounting holes are formed in the liquid crystal display element or the mounting position on the cabinet side is changed. It was

Therefore, a conventional method of installing a liquid crystal display device in a cabinet will be specifically described with reference to FIGS.

Generally, a method of mounting a liquid crystal display device in a cabinet is as shown in FIG. Liquid crystal panel 22
The liquid crystal display element 21 including the liquid crystal panel frame 23 and
As shown in FIG. 3A, mounting holes 24 for fixing to a cabinet 25 described later are formed at four corners of the liquid crystal panel frame 23.

On the other hand, as shown in FIG. 3B, a boss 26 is formed in the box-shaped cabinet 25. The bosses 26 are each formed in a portion that matches the mounting hole 24 of the liquid crystal display element 21. Further, a mounting hole 27 is formed in the boss 26 so as to match the mounting hole 24.

The liquid crystal display element 21 has the mounting hole 24.
Align the position of the mounting hole 27 with the position of
It is fixed to the cabinet 25 by.

However, when the outer size of the liquid crystal display element 21 is reduced, the mounting hole 24 of the liquid crystal display element 21 is used.
The position of the boss 26 of the cabinet 25 does not match, and it becomes impossible to fix the liquid crystal display element 21 to the cabinet 25.

Therefore, conventionally, as shown in FIG. 4, the position of the boss 36 is shifted so as to match the position of the mounting hole 34 of the liquid crystal display element 31 whose size is reduced. Thereby, the position of the mounting hole 34 and the position of the mounting hole 37 are aligned, and the liquid crystal display element 31 is fixed to the cabinet 35 with the screw 38.

Further, as shown in FIG. 5, a size-reduced liquid crystal display element 41 is provided with a mounting hole 44 formed to fit a new cabinet for the liquid crystal display element 41.
A conventional method has also been used in which a mounting hole 45 formed so as to fit in a conventional cabinet 46 is provided together, and the liquid crystal display element 41 is fixed to the cabinet 46 by the mounting hole 45.

A strong market demand for today's liquid crystal display devices is the slimming of products, that is, the reduction in size and weight. In order to meet such market demands, the product cycle of liquid crystal display devices has become extremely short.

Therefore, in order to reduce the external size of the liquid crystal display device, recently, a so-called side mount system in which a cabinet mounting portion is formed on a side surface of the liquid crystal display element body has become widespread. Due to the reduction in the size of the liquid crystal display element body or the change to the side mount method as described above, there is a problem that the existing cabinet cannot maintain the mounting compatibility with the newly developed liquid crystal display element.

That is, since the mounting position or mounting method between the newly developed liquid crystal display device and the existing cabinet does not match, it is necessary to create a new cabinet or change the mounting position of the cabinet. Each time the system is changed, the cost of making or modifying the cabinet is incurred.

As a means for solving the above problems,
There is a method in which a newly developed liquid crystal display element is provided with a mounting hole at the same position as a cabinet mounting hole of an existing liquid crystal display element. However, such a method has a problem that the merit due to the reduction of the outer size of the liquid crystal display element is impaired.

The present invention has been made in view of the above problems, and it is an object of the present invention to suppress the manufacturing cost of a liquid crystal display device by using existing cabinets for liquid crystal display elements having different sizes and mounting methods. To do.
