いて説明する。2. Description of the Related Art In recent years, demands for thinner and lighter display devices for use in television displays and computer terminals have been increasing. Since liquid crystal display devices can be made much thinner and lighter than conventional display devices, they have been actively developed and put into practical use. Hereinafter, a conventional liquid crystal display device will be described with reference to FIG.

ている。In general, a liquid crystal display device has a structure in which a plurality of flat internal members are stacked, and the internal members are fixed by sandwiching and fixing the holding members such as clips. The internal member is formed by laminating a cell 16, a circuit board 18, and an illuminating portion such as a backlight if necessary, and a spacer 15 is provided around the periphery for positioning these.

First, the end of the clip 14 is opened to a thickness equal to or larger than the thickness of the internal member fixed using a special jig, and the internal member positioned by the spacer is inserted into the clip 14. And then remove the jig,
The internal member is fixed using the restoring force of the clip.

ため、生産効率の低下が懸念されている。However, there has been a problem that the clip 14 is suddenly restored due to the momentum from which the jig is removed, and the internal member is damaged. For this reason, clip 1
It became necessary to adjust the opening width of 4 so as not to give an impact to the internal member, and the production efficiency was significantly reduced. Further, since such adjustment needs to be performed for each of the internal members having different thicknesses, the working efficiency is further remarkably reduced. Particularly, as described above, internal members such as a glass substrate used for the cell 16 are fragile because they have been reduced in thickness and weight in response to demands for liquid crystal display devices in recent years. There is a concern about the decline.

る。These components are positioned by a frame 2 made of, for example, plastic. An internal member is composed of the above components. An appropriate position around the internal member is fixed using a holding member 1 made of, for example, stainless steel as shown in FIG. Since the side end thickness 9 of the fixing portion is smaller than the opening width 11 of the holding member 1, there is no need to use a special tool when inserting the internal member into the holding member 1, and as the internal member is inserted, The opening width of the holding member 1 is automatically optimized. Therefore, there is no danger of giving an impact to the internal member unlike the conventional display device. For this reason,
The production efficiency is dramatically improved as compared with the conventional display device.

手段である。By using a holding member as shown in FIG. 3 as the holding member, the entire side surface of the internal member can be protected. The fixing portion 30 is not limited to both ends of the holding member, and may be formed, for example, in the present embodiment so as to correspond to a gap between the TAB-ICs. Further, as shown in FIG. 4, the bottom of the display device can be protected by forming the cross section of the portion indicated by A of the holding member 1 into a U-shape. In particular, the TAB-IC
In the case where is used, since the TAB-IC is extremely fragile, protecting with the holding member in this way is an extremely effective means.
