Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a structure for holding a liquid crystal display element.

Conventional technology For example, in a transmissive liquid crystal display element 1, as shown in FIG. 9, a driving side signal line 3 and a common side signal line 4 are formed on mutually opposing surfaces of transparent glass substrates 2a and 2b. is,
A liquid crystal is interposed between each signal line 3.4 in a sealed state. Each signal line 34 has a TAB (Tape\utos+ated Bondin) on which a semiconductor chip is mounted.
g) The board 5 and the mounted circuit boards 6, 7.8 on which electronic components such as capacitors are mounted are connected. The liquid crystal display element 1 thus constructed is held between bezels 9 and 10, which are holding means shown in FIGS. 10 and 11, respectively. That is, bolt insertion holes 11 and 12 are formed in each of the bezels 9 and 10 at positions corresponding to each other, and nuts are screwed onto the bolts inserted into each of the bolt insertion holes 11 and 12, and these bezels are assembled. The liquid crystal display element 1 is held by 910. These bezels 9 and 10 are made of metal, for example.

Problems to be Solved by the Invention In such prior art, as described above, the bezel 91
The shape of 0 corresponds to the shape of the liquid crystal display element 1, as shown by reference marks 13a to 13C in FIGS. 12(1) to 12(3), respectively, and the pixels of this liquid crystal display element 1. The numbers are 640 horizontal x 200 vertical dots (Figure 12 (1)), 640 horizontal x 400 vertical dots (Figure 12 (2)), and 640 horizontal x 480 vertical dots (Figure 12 (3)). If they are different, bezels having different lengths in the vertical direction (vertical direction in FIG. 12) and the same length in the horizontal direction (horizontal direction in FIG. 12) are used on the front and back sides of the liquid crystal display element 1, respectively. 3
These frame-shaped bezels, which must be manufactured in different types, are formed by, for example, punching, and there is a limit to the ability to punch out panels in sequence from larger panels to smaller ones. Furthermore, when the configurations are completely different, such as reflective liquid crystal display devices and transmissive liquid crystal display elements that use thin electroluminescence as a backlight, there are not only differences in length in the vertical direction as described above, but also differences in shape. Therefore, the problem arises that the number of types of bezels increases unnecessarily.

Accordingly, an object of the present invention is to provide a holding structure for a liquid crystal display element that can reduce the number of types of holding means such as bezels as much as possible to improve productivity.
