開昭５４−１３２２８７号公報）。In conventional liquid crystal display devices, the liquid crystal element and the printed circuit board on which the circuit for driving the liquid crystal element is mounted are fixed using a conductive rubber connector and a metal frame. Public bulletin).
上記従来例では、組立工数の点について配慮がされてお
らず、組立に時間がかがるという問題があった。In the above conventional example, no consideration was given to the number of assembly steps, and there was a problem in that assembly took time.
本発明の目的は、組立工数を軽減し、しがも高信頼性の
液晶表示装置を開発することにある。An object of the present invention is to reduce the number of assembly steps and to develop a highly reliable liquid crystal display device.

ールド４で液晶索子１とプリント基板２を仮止めする。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 shows an exploded perspective view of a liquid crystal display device according to the present invention, and is a printed circuit board on which a liquid crystal element 1, which is formed by sandwiching a liquid crystal between a pair of substrates having electrodes on their inner surfaces, and a drive circuit for driving the liquid crystal element 1 is mounted. 2 are connected by a heat seal 3 (manufactured by Nippon Graphite. Printed wiring is formed on an insulating sheet, and electrical connection can be made by heat adhesion). Next, the liquid crystal cable 1 and the printed circuit board 2 are temporarily fixed with a mold 4. .

切り取る。At this time, the cushioning material 5 is inserted between the liquid crystal element 1 and the mold 4, and between the printed circuit board 2 and the mold 4, respectively. This improves the connection strength of the heat seal 3 and prevents scratches on the liquid crystal element. The entire display device assembled in this way is first wrapped in a heat shrink tube 6, and then hot air is applied to shrink the heat shrink tube 6 to back the entire device as shown in FIG. This allows each component to be securely fixed by contraction of the tube. Finally, a portion of the heat shrink tube 6 corresponding to the display area 7 of the liquid crystal display element 1 is cut off.
