Description of the Related Art As shown in FIG. 6, a liquid crystal panel 6 and a printed circuit board 7 in a liquid crystal display device are formed by a TAB (Tape Automated) on which a liquid crystal driving circuit such as an LSI (Large Scale Integrated Circuit) or an IC is mounted. Bonding: tab) connected by a film 5. For this connection,
One side 5a of the TAB film 5 is thermocompression-bonded to the edge 6a of the liquid crystal panel 6 via the anisotropic conductive adhesive layer, while the other side 5b is connected to the printed wiring board 7 by cream solder. However, since the TAB film 5 is usually used after being rolled and rolled, the curl (warpage deformation) remains on the other side edge 5b of the TAB film 5. For this reason, there is a problem that the TAB film 5 rises or warps from above the printed wiring board 7 and the other side edge 5b of the TAB film 5 cannot be completely and satisfactorily soldered to a predetermined position of the printed wiring board 7.

を与えない。In the assembling process of the liquid crystal display device, one side edge of the liquid crystal panel and the TAB film are thermocompression-bonded, and the adhesive fixing surface of the temporary fixing tape peeled from the release paper near the cream soldering position of the printed wiring board. And then peeling off the backing of the temporary fixing tape to expose the adhesive. Next, the other side edge of the TAB film is temporarily fixed on the printed circuit board by overlapping and bonding the other side edge of the TAB film to the adhesive on the printed circuit board. At this time, since the adhesive of the temporary fixing tape is applied on the backing paper with a corresponding interval between the wiring patterns on the printed wiring board, the adhesive can be securely attached between the wiring patterns, There is no danger of the adhesive coming into contact with the wiring pattern. The adhesive remains between the two even after the TAB film is soldered to the printed wiring board, but does not adversely affect the product because the adhesive itself is a thin film.

のであれば足りる。柔軟薄紙では作業がし難い。FIG. 1 is a plan view of a temporary fixing tape A used in the present invention. The temporary fixing tape A is formed by applying adhesives 1 on one surface of a thin and narrow mount 2 at predetermined intervals in a thin film form. The distance between the adhesives 1 is set to a distance corresponding to the distance between the wiring patterns 8 of the printed wiring board 7, that is, a distance that can avoid the wiring pattern 8.
The adhesive 1 is a double-sided adhesive and its material is not limited, but is usually a conventionally known commercially available synthetic resin adhesive. The adhesive 1 is extremely thin so that its thickness does not adversely affect the TAB film or the printed wiring board when assembling a liquid crystal display device requiring precision. 3 easily adheres to the printed wiring board and the TAB film. The length and width of the mount 2 are determined by the size of the liquid crystal panel, and are usually about 2 mm to 10 mm. The paper quality and thickness of the backing sheet 2 are not particularly limited, but are relatively hard.
Anything that is convenient for mounting on the printed wiring board during the assembly process is sufficient. It is difficult to work with flexible thin paper.
